2. Show HN: Ldump – serialize any Lua data
URL: https://github.com/girvel/ldump
Author: girvel
Description: Some time ago, I was implementing saves for my LOVE2D game. I wanted to do a full dump of the game state -- which included closures (AI), complex graphs, sets with tables as keys and also fundamentally non-serializable data (coroutines and userdata), that require user-defined serialization/deserialization logic. I went through every Lua serialization library -- none covered all data types/cases. So I wrote my own.
It is a polished version, thoroughly annotated, tested and documented. It is made to be as functional and customizable as possible (or at least I did everything I could think of). I would be happy to hear suggestions/corrections for both code and documentation -- even nitpicky ones.

4. Show HN: Simple to build MCP servers that easily connect with custom LLM calls
URL: https://mirascope.com/learn/mcp/server/
Author: wbakst
Description: Hi!
After learning about MCP, I'm really excited about the future of provider-agnostic, re-usable tooling.
Unfortunately I've found that while it's easy to implement an MCP server for use with tools that support it (such as Claude Desktop), it's not as easy to implement your own support (such as integrating an MCP server into your own LLM application).
We implemented a thin MCP wrapper that easily integrates with Mirascope calls so that you can hook up an MCP server and client super easily to any supported LLM provider.
Excited to see what people build with this!

6. Show HN: Tclint – chip design inspired dev tools for Tcl
URL: https://github.com/nmoroze/tclint
Author: nmoroze
Description: I used to work at a small semiconductor startup that wrote chip design automation infrastructure in Tcl. One of our engineers wanted modern dev tooling for Tcl but couldn't find any - so I decided to build it.
Since then, I've been working on tclint in my spare time. It now includes:
- A linter (with plugins to support non-standard commands)
- A formatter
- A language server + VS Code extension
tclint is already being used at my former employer and elsewhere. I have lots of ideas for improvements, such as more linter checks, better extensibility, deeper support for chip design formats (e.g., SDC-specific linter checks), and expanding the language server.
If you write Tcl, give tclint a try! I’d love to hear if you find it useful, and I’d especially love suggestions on what would make it even better.

7. Show HN: Interview Cheating Is on the Rise--Here’s How We’re Stopping It
URL: https://www.shivonai.com/
Author: Vraj911
Description: Hi HN,
We’re a small team of engineers from Shivon AI building Lyra, an AI-powered hiring tool that helps companies identify truly qualified candidates while detecting interview cheating.
The hiring process today is frustrating—companies spend hours screening candidates, only to realize later that some weren’t the right fit. This problem has become worse with AI tools making it easier for candidates to cheat in interviews, leaving hiring teams unsure if they’re getting the right person.
We saw how much time companies waste on screening and how AI-assisted cheating is distorting the hiring landscape. We wanted to build something that ensures companies focus on the right candidates—without relying on outdated screening methods.
Lyra monitors candidates’ audio, video, and screen activities during the screening round to detect any suspicious behavior or AI-assisted cheating. It then flags inconsistencies in responses, giving recruiters valuable insights to make more informed decisions. Our goal is to bring transparency to the hiring process while saving companies time.
We’re still in beta and would love feedback from the community. If you’re interested, we’re offering limited beta seats for free—just let us know! You can check out more details <https://shivonai.com/> or review the demo <https://youtu.be/ZpvlJYDiRLk>.
Would love to hear your thoughts, suggestions, or any experiences you’ve had with this problem!

URL: https://blog.val.town/blog/projects/
Author: stevekrouse
Description: Hello! We at Val Town have spent the last couple months redesigning our product around a new core primitive: Val Town Projects.
Why: Our prior core primitive, a "val", was too small. A val is just a single hosted JavaScript file. Users kept bumping up against rough edges managing lots of disparate vals.
What: A Val Town Project is a group of vals, files, and folders, versioned collectively. They support branches, forks, and merges.
How: We made the sacrilegious decision to not build on git. We instead built a simplified system that works directly in our postgres database.
Our dream is that Val Town Projects will unlock a new kind of collaboration, and we hope you all make amazing things with it!

12. Show HN: Interactive jq, but it's a bash script using fzf
URL: https://gist.github.com/Thomascountz/5ae98a738abb9246b9f7749f53cdddcf
Author: thomascountz
Description: I was searching for an interactive jq editor when I came across this repo [1], which had an intriguing suggestion for a CLI using only fzf:
echo '' | fzf --print-query --preview "cat *.json | jq {q}"
This sent me down a rabbit hole, and I discovered just how incredibly configurable fzf is.
For instance:
- --bind=ctrl-y:execute-silent(jq {q} $tempfile | pbcopy): You can bind custom keys to execute non-default behaviors, like copying the current selection or echo-ing.
- --query=".": Start fzf with an initial query (e.g., . for jq queries) to streamline the experience.
- --preview-window=top:90%:wrap: You can configure fzf into different layouts, behaviors, and ANSI colors.
- --header=$'ctrl+y : copy JSON\nctrl+f : copy filter\nenter : output\nesc : exit' \: fzf supports multi-line header to provide instructions or context for the user right in the interface.

Apple Podcasts: https://podcasts.apple.com/us/podcast/the-exploit-podcast-cv...
Spotify: https://open.spotify.com/show/6d4yfU1geTLIKtaY7lQJvm?si=YCrh...
We have tried to make it automated so that the creation of podcast is not a burden to us. To help in this, we built CVEingest[1], a tool that:
1. Crawls GitHub Advisory and CVE.org, along with referenced sources.
2. Fetches code diffs (if patch is present)
3. Generates a SSML script where host and guest are talking which can be used to create audio.
4. Creates an audio podcast via Microsoft Speech (or lets you download CVE data in JSON).
This podcast will help you stay ahead of emerging threats.

17. Show HN: Ros2_utils_tool, a powerful GUI toolset for ROS2-based utilities
URL: https://github.com/MaxFleur/ros2_utils_tool
Author: bakefish
Description: Hi Hackernews,
over the past few weeks, I've been tirelessly working on a GUI toolset for all sorts of ROS2-based utilites to simplify my tasks with ROS at work. Now I want to present to you the ros2_utils_tool.
This tool can do many ROS2-based utilites, for example editing a ROS bag file to remove, rename or crop topics, extracting a video or image sequence out of a ROS bag, creating dummy bag files or just publishing a video as a ROS topic.
While being developed to be as simple and lightweight as possible, the toolset supports many advanced options, for example different video and image formats, custom fps values, switching colorspaces and more. I've also heavily optimized the tool to support multithreading or in some cases even hardware-acceleration to run as fast as possible.
The tool offers full graphical user interface support for all features, while I've also added additional command line interface support for most of them.
As of now, the ros2_utils_tool supports ROS2 humble and jazzy.
The application is still in an alpha phase, which means I want to add many more features in the future, for example GUI-based ROS bag merging or republishing of topics under different names, or some more advanced options such as selecting messages for video or image generation.
The ros2_utils_tool requires an installed ROS2 distribution, as well as Qt6 or Qt5 for the user interface, the cv_bridge for transforming images to ROS and vice versa, and finally catch2_ROS for unit testing.
You can install all dependencies (except for the ROS2 distribution itself) with the following command:
sudo apt install libopencv-dev ros-humble-cv-bridge qt6-base-dev ros-humble-catch-ros2
sudo apt install libopencv-dev ros-jazzy-cv-bridge qt6-base-dev ros-jazzy-catch-
cd path/to/your/workspace/src
git clone https://gitlab.com/nct_tso_public/mediassist4/ros2_utils_tool.git
cd path/to/your/workspace/

22. Show HN: LLPlayer – The media player for language learning, with AI subtitles
URL: https://github.com/umlx5h/LLPlayer
Author: umlx
Description: Hello HN!
I've been developing a video player in C# and WPF for the last 8 months, and now that it reached a certain quality, I'd like to publish it.
github (source, release build) http://github.com/umlx5h/LLPlayer
website https://llplayer.com
LLPlayer is not a normal media player like mpv or VLC, but a media player specialized for language learning. I originally created it for my own English learning, but I have made it more versatile by adding various features.
It is completely free OSS under GPL license.
The main feature is automatic AI subtitle generation using OpenAI Whisper. (Recently, VLC has been in the news for doing the same thing, It doesn't appear to be public yet.)
Subtitles can be generated in real-time from any position in a video in 100 languages. It is fast because it supports CUDA and Vulkan. In addition, by linking with yt-dlp, subtitles can be generated in real time from any online videos. (By the way, Whisper is far more accurate than Youtube's subtitle generation.)
Other unique features include a subtitle sidebar, OCR subtitles, dual subtitles, real-time translation, word translation, and more.
I plan to add more language-specific features in the future, such as Japanese for anime fans.
I have prepared a demo video on GitHub, and I would be very happy if you could take a look at it if you are interested.
Currently, It only supports Windows, but I want to make it cross-platform in the future using Avalonia.
Note that I did not make the core video player from scratch in C#.
I used a .NET library called Flyleaf and modified it, which is a simple yet very high quality library. https://github.com/SuRGeoNix/Flyleaf
It would take a tremendous amount of effort to create a video player in scratch by just one person.
Without this library, LLPlayer would never have existed. Thanks for publishing it as OSS!
Feedback and questions are welcome. Thanks for reading!

URL: https://automata.iimaginary.com/
Author: iimaginary
Description: Last month, I stumbled upon an article about 1D reversible automata.
https://richiejp.com/1d-reversible-automata
I was struck by how simple mathematical rules could create patterns that look remarkably like microscope images of living cells. I had to explore this further, so I built Automata - an interactive visualiser where you can play with these patterns yourself.
(Tip: Start with Rule 75 in reversible mode - you'll see what I mean about cell-like patterns)
Excited to hear what you discover.
Thanks to @richiejp whose article sparked this project. I see he's built a very good explorer since I read the article but mine has a couple of different features so I think it's still worth sharing.

26. Show HN: cfnlite - a simple and sensible CloudFormation generator
URL: https://github.com/a777m/cfnlite/blob/main/examples.md
Author: arm93
Description: TL;DR cfnlite is yet another YAML based config file format, but its the last one, I promise. <insert-relevant-xkcd> I wanted to create a CloudFormation generator with a simple interface and better devUX.
Longer version: So I've recently found myself in a somewhat low code team which is pretty adamant on using CloudFormation for all IaC (we're all in on AWS). My background is mostly in building on-prem data centres and realtime video, so I'd never worked on "the cloud" before now. So, I spent the first two weeks speed running AWS basics and then another two weeks looking into IaC, mostly writing CFN.
Very quickly I realised that working with raw CloudFormation is an PITA. I tried everything to create sensible, reusable, modularised templates - you know the kind of ideals most of our other code is built on - but it just become a pile of parameterised garbage.
Anyways, I then discovered all the options for imperative IaC (CDK, troposphere etc), and had a mess about with those. Heres a hot take: I actually think YAML is better than most of the imperative stuff for at-a-glance debugging/understanding. Regardless, I knew for sure the team was never going to agree with using any of that (they said so lol).
So I decided to build a little library for myself so that I could at least generate CFN for my own work. One thing lead to the other and I decided I could make some kind of CLI tool that takes a small config file and generates the CFN. That way, I wouldn't even need to write custom CDK code for each new CFN template I wanted to make.
And thus the beginnings of cfnlite was born. It kind of started with a series of "What if..." type questions:
- What if I could generate CFN from a small config, what would that config look like?
- What if I didn't have to actually remember what CFN calls each type of resource?
- What if it gave me all the required fields with some defaults?
- What if I could validate types without needing to run the template?
- what if the library could resolve dependecies and do all the !Ref/DependsOn stuff?
- What if it had loops and simple ternary conditions? (haven't answered this one yet)
After a while I realised I could create something in a language agnostic interface, an interface that the team already knew but would also hugely simplify mine - and hopefully my teams lives. I'm also a compiler nerd so I was never going to let the chance to write a code generator pass-up.
I recognise to most I've just recreated a shoddy terraform (although this tool is heavily inspired by Ansible, my fav YAML based IaC) that nobody else will probably ever use but within my constraints, it solved a real problem and more importantly, has been super fun to work on.
How it works
Its basically a wrapper around troposphere:
- yaml config comes in, it gets parsed
- cfnlite builds a dependancy tree based on ref's and DependsOn
- maps user input to troposphere objects for each resource (most of the logic is here)
- spits out the template to stdout or a file

Author: mukundala
Description: What does this app do?
If you are preparing for exams and have a whole set of questions, you can organize your questions as per a simple structure, load them into the app and start revising.
Why this app?
I recently started preparing for AWS certifications. For revising the topics I used AI and AWS documentation to generate a huge set of questions. But then I didn't find any tool/app into which I could load these questions easily. Even the one that I found was a little complicated and not serving my purpose (sorry I forgot that app's name). So I quickly put together this app using plotly dash.
What was my requirement based on which this app is designed?
I wanted a simple interface where the app
1. shows the question with choices 2. I make a choice 3. The app shows the correct answer 4. Along with the correct answer, explanation and reference url are provided.
That's it. Simple process to memorize and master some topics.
I'm going to be using this extensively to prepare for my exams. I also plan to publish my question sets once my preparation is complete for each certificate. Hope someone finds this useful.
Initially I had plans to have score, analytics and such. But then I didn't want to spend too much time on this app. Maybe in future I will add those as well when I'm relatively free.

32. Show HN: TemplateDocs – An API for generating PDF documents from DOCX templates
Author: alonbar
Description: Hey HN,
I built TemplateDocs (https://templatedocs.io), a service that lets you generate documents from Microsoft Word templates using a simple API or web interface.
I previously created easy-template-x (https://github.com/alonrbar/easy-template-x), an open source library for generating Word documents (~30K downloads/month). After leaving my job at a big tech company, I decided to turn my experience with document generation into a proper SaaS product.
TemplateDocs lets you:
- Use regular .docx files as templates with a simple {{variable}} syntax
- Generate documents via REST API or web interface
- Keep all your Word formatting (fonts, styles, tables) intact
- Handle loops for dynamic content like invoice line items
- Get output in DOCX or PDF format
The web editor lets non-technical users generate documents without coding, while developers can integrate it into their workflows using the API.
There's a small free tier (20 docs) and pricing starts at $9 for 500 documents (one-time payment) up to $99/month for 25,000 documents.
Would love to hear your feedback! Next things I thought of working on:
- Zapier, Make.com and n8n integrations.
- Adding template features like inserting images and links.

36. Show HN: Pause – Unbreakable Focus Timer
URL: #
Author: Hahahadrien
Description: Hey HN,
I built Pause, a radical anti-distraction app that helps you stay focused by blocking all apps with a timer you can’t bypass.
Like many, I often found myself mindlessly scrolling on my phone when I should be working, reading, or just enjoying a break.
App blockers exist, but most can be disabled too easily. Pause is different: there is no way around it – it blocks all your apps, and you have to wait until the timer ends. Simple and effective – no extra fluff, just deep focus. It’s perfect for work, study, reading, or reducing phone addiction.
If you’ve ever felt the urge to "just check something real quick" and lost 30 minutes instead, Pause is for you.
Would love your feedback! Download, try it, and let me know what you think.

38. Show HN: LightCombatManager 3.0 – A simple combat manager for d20-based RPGs
URL: https://github.com/MaxFleur/LightCombatManager
Author: bakefish
Description: Hi HN,
almost two years ago, I presented LightCombatManager (or LCM) to you [0]. Since then, I've added countless new features and other improvements.
In short, LCM is a tool to manage combats for all sorts of d20-based role playing games. Via a simple and intuitive dialog, characters can be easily created and added to a combat table. The combat table can then be edited in all sorts of ways - dragging and dropping rows if characters move their initiative, deleting entries for killed characters or enemies, apply status effects... many convenience features such as undoing changes, shortcuts and context menu entries are also supported.
LCM supports many different d20-based RPG systems, for example DnD 3.0E/3.5E/5E or the Pathfinder games. It runs on all major desktop platforms, which are Linux, Windows and MacOS.
Since my first post, I've added many more use- and powerful features, such as an enhanced status effects display, storing characters as templates so they can be added into a combat even faster, the ability to add multiple characters (for example minions) at once, a nice new toolbar and logging widget showing the most recent actions done, custom icons and many more things.
I've also did tons of work for the infrastructure behind the code. LCM now supports MacOS, Qt6 and a few C++20-based features. Additional CI was also added for all three major platforms.
For the future, even more features are planned, such as storing custom status effects.
If you want to tryout LCM, check the most recent releases under [1]. If you want to build it yourself, you need Qt6 or Qt5, Catch2 and CMake. On Ubuntu, the following command will install all dependencies at once:
sudo apt install qt6-base-dev libqt6svg6 libqt6svg6-dev catch2 uncrustify cmake
1. Clone the repository [2].
2. Open a terminal and cd into the repository dir.
3. Hit
mkdir build
cd build
cmake ..
make

39. Show HN: Test automation that doesn't suck
URL: https://app.magnitude.run/demo
Author: thrgreenwald
Description: Hey HN. We’re two devs building Magnitude (magnitude.run), a software testing platform to eliminate brittle and high-maintenance testing. It uses LLM-powered web agents to execute natural language test cases while identifying specific bugs along the way.
There’s plenty of buzz around web agents and new approaches to automated testing, so what makes our product different? Our approach is web-native, provides dynamic yet consistent behavior, and is packaged in an all-in-one solution so that you can forget about maintaining internal tools for testing.
With Magnitude, you’re able to create test cases in natural language that just work based on what you intend, rather than relying on a particular webpage structure. Instead of brittle test failures becoming white noise, you’ll know that when a test fails, it means real users could be impacted.
If you’d like to give this a try, check out our preview. We’d love to hear what you think about it.

43. Show HN: Word Dynasty
URL: https://pingtype.github.io/wordDynasty/index.html
Author: peterburkimsher
Description: Word Dynasty is like Bejeweled, but for letters.
• It draws lines for each word, and lists them at the bottom of the page.
• Click any two tiles in sequence to swap the letters.
• I suppose the goal is to find as many words as possible, or one word per line.
Known issues:
• The grid sometimes looks wider than the page on mobile.
• It needs a Readme and icon.
• Overlapping lines just look like one long line.
• Sometimes the lines get drawn wrong and they get offset left by a few pixels. Not sure why.
• It doesn't handle diagonals yet, just horizontal and vertical.

44. Show HN: I made a local, private AI friend
URL: https://heyamy.ai/
Author: qualitywithin
Description: As children, we had imaginary friends. When LLMs came about, I thought we could finally bring imagination into reality - a physical embodiment that may even be helpful to children’s growth.
I made Amy as a fun side project.
Some things that I thought were important:
- Conversations and data had to stay local and private. They shouldn’t go to an API somewhere, and I shouldn’t have to pay more to talk to Amy more
- Amy should be cheap. A chip like Nvidia’s Jetson Orin Nano costs ~$250 alone, so this in particular was tricky
- Amy doesn’t and shouldn’t need to be everywhere - on your phone, tablet, etc. There’s beauty in a simple physical embodiment
This is a prototype and I'd appreciate any feedback, but I'll make more if there's interest!

URL: https://github.com/ahrm/voil
Author: hexomancer
Description: I wrote a vscode extension which allows you to create/rename/move/delete files by editing a text buffer. If you are familiar with oil.nvim, this is similar. In my opinion this is vastly superior to the built-in file manager because it allows you to utilize your existing text-editing muscle memory into file manipulation skills, as opposed to the built-in file explorer which requires mouse or at least memorizing new keyboard shortcuts. There is a video demo on the github page.

48. Show HN: Anki Deck Builder
URL: https://github.com/pushpankar/anki-deck-builder
Author: pushpankar
Description: Hi HN, I built an automatic deck builder for anki. As a non-native english speaker but avid reader, I find that I don't know many words while reading a book. While I can approximate the meaning, it slows me down and many times I move on with ambiguity. Sometimes the words are critical in the context but I don't like to pause and lookup in dictionary. Even if I do, I tend to forget them soon.
Also, Anki is the best tool for long term retention but building a deck is cumbersome. So, I built this tool to extract the words from the book I am reading and add those to my anki deck.
It is free, give it a try and share your feedback or features you would like to see.
Thanks, Pushpankar

Author: ainarsklavins
Description: Hey HN,
My mother does not read English, but there are many great books about health, longevity, and other important topics that are only in English. I am not ready to wait years for them to be translated. So, I created this booktranslator.ai so anyone could translate books and read them in their native language.
The first users of my product also shared that they sometimes translate this book because it is easier for them to read in another language than when the book is released.
A side story - I just learned to code and switched to Cursor to speed things up, so this is the first project I have created from scratch to launch. Here is the power of the Cursor. AMA.
Maybe you can also find a use for such a tool.

51. Show HN: CommitGenius – AI-Powered Commit Messages with Zero Setup
URL: https://github.com/bannawandoor27/Commitgenius
Author: bannawandoor27
Description: Hey HN,
I built CommitGenius, a CLI tool that generates commit messages based on your code changes—completely offline using local LLMs (via [Ollama](https://ollama.ai)).
### Why?
I got frustrated while writing commit messages during a coding session. Instead of wasting time, I took a quick 20-minute break, fired up Windsurfer IDE, and built this tool. Sometimes, the best solutions come from just scratching your own itch!
### What It Does
- Analyzes your staged code changes to understand what you've done
- Generates clean, conventional commit messages that actually make sense
- Works 100% offline—no cloud dependencies, no context switching
- Minimal setup—just install and run
### Quick Start
cargo install commitgenius
git add .
cmgenius
Example output:feat(auth): improve JWT token validation and error handling
Would love to hear your thoughts—any feedback or ideas to improve it? Also, what’s the most useful tool you’ve built in a single coding session?

57. Show HN: Automate the Creation of CI/CD Pipeline from Hours to Minutes
URL: https://github.com/ARAldhafeeri/Blaze-cicd
Author: araldhafeeri
Description: Blaze CI/CD is a Command Line Interface (CLI) tool designed to automate the creation of production-ready CI/CD pipelines. The tool integrates with Kubernetes, Docker, DockerHub, GitHub, GitHub Actions, and ArgoCD to provide a seamless setup experience. Users provide essential details such as project name, API keys, and application configurations, and the tool handles the creation of namespaces, repositories, and CI/CD pipelines.
Automated Pipeline Creation: Automates the setup of CI/CD pipelines using Kubernetes (kubectl), Docker, GitHub, and ArgoCD. YAML Configuration: Users provide project and application details via a YAML configuration file that will be used to construct the entire CI/CD pipeline with a single command. Multi-Service Integration: Integrates with DockerHub, GitHub, and ArgoCD to create repositories, projects, and applications. Can handle pipelines for multiple services. CLI Interface: Simple command-line interface with init and build commands. Minimal Setup: Other than configuring kubectl, Python, installing the package, and providing API keys, there are no additional steps other than filling out the config.yaml. Graceful Degradation: Blaze CI/CD ensures robust pipeline creation by verifying the existence of resources at each step. If a resource (e.g., repository, project, or application) already exists, Blaze skips its creation to avoid redundancy. If a resource is missing, it creates it automatically.
