2. Show HN: I Built Squids.Games: Track YouTube Stats with a Squid Game Twist
Author: sleepy_duck
Description: Hi HN,
I’ve launched Squids.Games, a website that tracks YouTube stats—likes, dislikes, views, and more—inspired by the life-or-death competition vibe of Squid Game. While no actual games are played here, the site serves as a fun and dramatic way to visualize how creators are battling it out for attention and engagement on YouTube.
The idea came from watching how the world of content creation has turned into its own high-stakes arena, where stats can make or break a creator's success. Squids.Games gives you a clear snapshot of who’s “winning” the game on YouTube, and who might be falling behind.
It’s a simple concept right now—just tracking numbers—but I’m exploring ways to make it more interactive and insightful.
I’d love your thoughts on:
What additional stats or features would you like to see? Does the Squid Game metaphor resonate with how you see social media today? Any ideas to take this further? Thanks for checking it out, and I look forward to your feedback!

3. Show HN: Data Connector – Chat with Your Database and APIs
URL: https://github.com/inferablehq/inferable/tree/main/data-connector
Author: johnjcsmith
Description: Hey HN!
Wanted to share a project I have been working. Data Connector is an open source tool for interacting with Databases (Postgres, MySQL, SQLite) using natural language. Prompts are handled using a ReAct[1] agent which has access to the schema and a tool for executing queries.
It also has experimental[2] support for calling APIs (OpenAPI, GraphQL) which allows for queries that can span multiple systems (Find this user's details in Clerk, etc).
We have mostly been using it for managing our local development environment, but it has configurable controls for running in other environments.
- Privacy Mode which never sends query results back to the LLM context, instead the result is returned to the user as JSON
- Approval Mode which requires manual approval of each query before it is executed
Data Connector runs within a private subnet, connects to the database and polls for new queries. There is no requirement to open traffic to the database or share credentials / connection strings.
Data Connector is built using another project we are working on Inferable (also open source) which is a runtime for building and observing LLM-based agents.
Would love your thoughts!

[2] We have been testing these with various schemas and are currently working on better handling for large OpenAPI specs, etc.

URL: https://feedhunt.app
Author: Yeeze
Description: Hey HN,
I’ve been frustrated with feedback tools like Canny for a while now. They’re packed with features I didn’t need, overly complicated, and the pricing ($359/month!) just doesn’t feel indie-friendly.
So, I spent the last few months building Feedhunt—a lightweight alternative for indie makers and small teams. It’s simple, affordable, and focused on what matters:
- Collect feedback from your users
- Let them vote and prioritize features
- Build a product users love without guesswork
- Fully customizable boards (logos and themes)
- Indie-friendly pricing: no subscriptions, just $18 for 3 months or $72 for a year
Tech stack: Nextjs, PostgreSQL. Focused on being lightweight and solving real problems.
Check it out at feedhunt.app. I’d love to hear your thoughts or feedback on what could make it better. Thanks for taking a look!

10. Show HN: Checkmate, a server and infrastructure monitoring application
URL: https://github.com/bluewave-labs/checkmate
Author: gorkemcetin
Description: We just released Checkmate 2.0 (formerly BlueWave Uptime). Originally designed as a simple uptime manager, Checkmate has evolved into an infrastructure monitoring tool.
With the addition of our lightweight Go-based server agent (Capture) it's possible to monitor key metrics like CPU, RAM, and disk usage across remote servers.
We’re now exploring new features, including enhanced notifications, advanced configuration options, DNS monitoring, and status pages (which are almost ready to launch btw). There are no plans for synthetic monitoring, APM, log management, traces etc. It'll hopefully stay as small as possible.
It's still the early days for Checkmate. The project gained some traction with 31 contributors and this version itself had 13 contributors.

URL: https://github.com/Bananymous/banan-os
Author: Bananymous
Description: This is my operating system that I've been working for the past 2 years. All of the code is written exclusively by me except from ported software. banan-os has a monolithic kernel targeting x86 (i686) and x86_64 architectures. The project consists of bootloader, kernel and userspace libraries (libc, libGUI, libFont, ...). It also uses my custom C++ standard library partly based on stdc++.
Currently I have basic TTY and GUI environment with some of the basic UNIX utilities like cp, ls and stat. I have basic support for USB (keyboard/mouse/storage), disks (NVMe, AHCI), custom networking stack with TCP and UDP support, and a UNIX-like filesystem with /dev /tmp /proc filesystems.
The whole project is written in C++ except for my BIOS bootloader that is written in 16-bit real mode assembly. I have been testing the OS mainly on virtual machines but also frequently on real hardware.

19. Show HN: Sourcetable – "Cursor for Spreadsheets"
URL: #
Author: mceoin
Description: Hi HN! I’m Eoin, founder of Sourcetable (https://sourcetable.com).
Sourcetable is a web-based spreadsheet that lets users pair with AI to do better, faster work. If you spend a lot of time in spreadsheets doing fairly repetitive grunt work, there's a good chance Sourcetable can massively increase your productivity so you can spend your time on more interesting things.
There are two ways people primarily interact with AI inside Sourcetable: the sidebar (CMD + ), which is great for document or range-based analysis, and the command bar (CMD + K), which is handy for cell-based operations. This is because spreadsheets have inline workflows and meta workflows, somewhat similar to Cursor's text editor UX.
The fastest way to use the product is to upload an XLSX or CSV file and start asking questions.
Sourcetable's AI is helpful with workflows including data cleaning, formula assist, chart generation, research, analysis, language translation, data transforms, thinking through problem solving, error handling, etc. If you can ask an AI to do it, it might just work!
The best way to get value from the Sourcetable is to remember that you are pairing with very helpful LLMs, but not (yet) an all-powerful AI. It doesn't do everything for you, but it will make curious people more productive.
One thing the HN crowd might find interesting is that we have put a lot of work in making sure answers are hallucination free wherever possible. We do this by having the LLM write code which our backend validates and executes. If you're using the AI chatbot for analysis, open the code editor and have a look!
I'm constantly surprised by the breadth of users and use cases. We have seen soil scientists, virtual assistants & EAs, MBA students, criminologists, oil refineries, telemarketers, astrologers, sales ops folk... etc, using the product. Considering we set out to build Sourcetable for operations folk, it has been a pleasant surprise to see just how useful and broadly applicable an AI native spreadsheet can be to society.
On the technical side, Llama 3.1 (via Groq) and Claude 3.5 are the work horses. LiteLLM handles load balancing to work within RPM & TPM constraints, and OpenAI models are the backup. Our spreadsheet is DuckDB based which has big speed advantages for regular spreadsheet & data work, and also for keeping our AI agents fast.
Finally, Sourcetable is free for students (freemium for everyone else), just sign up using your student email. If you have product feedback, we would love to hear from you: eoin@sourcetable.com

20. Show HN: Generate Gravity Forms with AI
URL: https://gravitybuilder.ai
Author: harness_up
Description: At my previous company we leveraged the popular Gravity Forms plugin for WordPress to build forms for clients. We built A LOT of forms. However as good as their drag & drop editor is we still had to spend hours creating most forms. We would need to make sure the form had all the correct fields, populate certain types of fields like checkboxes with choices. Then we would want to ensure the form had an optimal layout so that users could complete it easily. This required us to add section and page fields. We also would use tricks like "conditional logic" to show or hide fields based on previous inputs.
Many clients didn't know exactly what they wanted when it came to forms. A typical request might be "Give me a vehicle inspection form" without specifying what fields the form should have. This required our staff to spend additional time planning out the form before actually building it. It was slow and expensive.
This is why we build Gravity Builder AI.
Now we can generate new Gravity Forms either by entering a prompt OR uploading a document example. In seconds, we get a well designed form ready for testing.
Here are some videos of how it works:

We can even build forms in other languages!
https://www.loom.com/share/f28cd1ba556f429d90bd8ed490b0a7e5?...
Gravity Forms is one of the most popular plugins ever for WordPress. Are you using it for your site or recommending it to clients? We'd love for you to try out Gravity Builder AI. There is a FREE version available on our website: https://gravitybuilder.ai
Let me know what you think of the product. Cheers!

Today I want to celebrate and share with you, again, a game that I conceived more than 8 years ago.
I shared it last week with all its history (if you're curious) [1], but it just stayed in the "shownew" and never reached the main "show" page, hopefully this time it'll do better (:crossed_fingers:)!
What changed since last week? Today I've also published the mobile apps for both iOS and Android (last week it was just web), which are also my first mobile apps ever. So I believe it's still a worthwhile post and something to show :)
I'd love to know what you think about it. I'll try to answer to everyone during the day.

However contribution experience can very bad, if you follow the path of picking the most famous objects. Good luck contributing to Node, Rust, Shadcn and etc - they do not need your contribution, their PR queue is overloaded and they can't handle it. Plus you need to get to their internal circles first, though quite complex process.
The world is much bigger. There are so many help required from the smaller but still active projects.
Just recently I raised 3 small PRs, and they reviewed the same day!
As a my respect to all the OSS community, I have build this website, which in the nutshell shows latest "help wanted" and "good first issue" issues, from all over github in the last 24 hours.

KanthorQ - Messaging System Backed by PostgreSQL
Repo: https://github.com/kanthorlabs/kanthorq Docs: https://docs.kanthorlabs.com/kanthorq/
I designed, developed, and maintained it to address most of my use cases. Here are some key features:
- Transactional enqueuement: Helps avoid situations where you successfully enqueue a message, but your compute is lost, or the opposite scenario occurs.
- Message persistence: Messages are stored in the database indefinitely until explicitly deleted. This makes tracing, monitoring, and debugging much easier.
- Categorization by subjects: Simplifies message filtering and organization by subject.
If you're familiar with NATS.io, you'll find it easy to get started with KanthorQ. I was an avid user of NATS.io, and it inspired me greatly while designing KanthorQ.
Some example usecases
- Webhook gateway
- Batch jobs
- Notifications

28. Show HN: I built a practice planner and drill library for basketball coaches
URL: #
Author: jordanmorgan10
Description: Hi HN,
Living around a few college coaches, I discovered some common pain points around saving drills and planning+running a practice. The crossover of those pain points with youth coaches was similar.
So, I built an interactive practice planner and drill library into my indie basketball coaching app, Elite Hoops[1].
I built it around three verbs, "Plan", "Run" and "Build":
Plan Practices/Workouts/Tryouts: Use the drill library to be a source of building blocks for practices, tryouts and workouts.
Run and Share: Run practices from your phone (complete with automatic drill progression) or export plans as PDFs to share/print. Build them up from your drills, piecing them together like lego pieces.
Build Your Drill Library: I included 200+ preloaded drills, or coaches can create their own, complete with descriptions, focus areas, and videos. This was key because a lot of coaches find drills they like on Instagram, TikTok, YouTube or fill-in-the-blank, but they save them all over the place. Now, they've got one spot for all of them.
For some fun technical aspects, I wrote up some SwiftUI details[2] on my own blog. And, I have the marketing post with feature details as well[3].
Anyways, I feel like basketball software usually isn't that exciting, so I'm trying to sneak into the niche with some (sigh, I know) innovative approaches. If you’re a coach or know someone who might find this useful, let me know what you think, always open to thoughts/feedback.
Thanks for checking it out! Jordan

31. Show HN: Built a City Explorer Because My Wife and I Got Tired of Switching Apps
URL: #
Author: Bnicovski
Description: Hey HN!
You know that feeling when you're exploring a new city, and you stop in front of this stunning building or quirky statue, but have no clue about its significance? That was me and my wife last year, constantly switching between apps and guidebooks instead of actually enjoying our travels together. After one too many times of saying "I wish we knew the story behind that," I decided to build Travo. It's a city guide that lives in your pocket, born from real frustration and countless hours of getting lost in beautiful places (sometimes intentionally, often not). I've spent the past year working solo on this, turning those travel pain points into something I hope makes exploring cities more enjoyable and less about staring at multiple screens. The goal? Let you wander freely while still knowing the rich stories behind everything you're seeing. Travo transforms your smartphone into an interactive city guide that combines maps, audio narration, and local insights. It helps you discover hidden gems and cultural landmarks at your own pace. Here's what you get:
Here's what you get:
- Audio storytelling that brings local history and culture to life
- Interactive maps that let you explore at your own pace
- 7-day customizable itinerary planning with optimized routes
- Use navigation points directly in your favorite app with public transport options
- Available in 13 languages for global travelers
- AI-powered historical and cultural insights that bring cities to life
- Extensive coverage of points of interest, powered by advanced AI technology
Perfect for independent travelers who love exploring at their own pace, culture enthusiasts eager to learn the stories behind city sights, and anyone curious about the history around them. I decided to keep the business model simple and traveler-friendly: explore 8 cities with free access, and when you find a city you love, unlock it with a one-time purchase to get access to all stories within 50km/31 miles around that city. You only pay for the places you want to explore.
Special for HN readers: use code HN2024 to unlock one city of your choice!
The challenging part? As a solo developer, I've had my share of late-night debugging sessions and moments questioning my sanity. I'd love to hear from fellow developers about managing projects solo, and from travelers about what would make this more useful for you. Particularly interested in your experiences with the interactive map and generated plans.

URL: https://njyoon.github.io/jumun/
Author: njyoon
Description: I loved playing the sliding puzzle Rush Hour as a kid and love making crosswords now, so I decided to combine the two with some Wordle mechanics. I've queued up enough daily puzzles to last the rest of the year, and hope you enjoy solving!
Some fun-for-me considerations:
- In normal number/picture sliding puzzles, half the configurations are unsolvable (Numberphile has a pretty good video on why this is). But having duplicate letters means that even if you are left with a single inversion in a 5x5 sliding puzzle (which usually indicates that the puzzle is unsolvable), you can often get out of it by switching duplicate letters.
- I'm not very good at math though, so if anyone can tell me the conditions under which switching duplicate tiles reverses parity, I'd love to know! Just in case all configurations aren't solvable, I ran some code to shuffle the tiles with legal moves when I set the daily puzzles.
- I'm very new to game design (this is my first one), but I've always enjoyed games and puzzles that can scratch both sides of my brain. Hope that comes across in this one!

Author: kaizarbharmal
Description: Hi HN,
I’m Kaizar, a student and founder of Growflyer, an all-in-one platform that helps website owners better understand their users and improve engagement. After three months of launching, Growflyer has earned its first $300, and I’d like to share my journey.
What is Growflyer? Growflyer is a toolkit for websites that combines:
Marketing Analytics: Real-time insights into user behavior. Feature Flags: Test and roll out features without deploying code. Session Replay: Understand where users are getting stuck. Custom Notifications: Engage visitors with personalized pop-ups and messages.
The Journey: I launched Growflyer with a simple goal: to help websites turn visitors into engaged users. The first few months were spent building the product while juggling university and an internship.
Lessons Learned:
Start Simple: The MVP focused on analytics and notifications. Over time, I’ve added more features based on user feedback.
Marketing is Key: Launching on different SaaS submission helped Growflyer gain visibility and early adopters.
Consistency Matters: While balancing school, I ensured consistent updates and support for users.
Feedback Welcome! I’d love to hear your thoughts on Growflyer. What features do you think would help website owners the most?
Thanks for reading, and I’m happy to answer any questions!

45. Show HN: Free and open source tool to count the code lines you pushed to GitHub
URL: https://git-contributions.streamlit.app
Author: ggay
Description: GitHub contribution graph is cool but only represents commits on master branch.
I was curious about the total number of lines I've pushed this year from all my contributions across all the branches of all the repositories (even the private ones).
Spotify is sharing stats about top artists or number of streams, Strava about distance and elevation, but there's no tool for the developers.

48. Show HN: KlerkAI – Instant Idea Validation from millions on Reddit
URL: https://klerkai.com
Author: talhadar
Description: Hi HN community,
I've built klerkAI, an AI tool that searches through millions of Reddit posts to provide instant validation and feedback on business ideas. The goal is to help make informed decisions backed by data from genuine conversations on Reddit.
Backstory:
Whenever I'm starting a new project, Reddit is my go-to place for research. But manually going through threads can be time-consuming. So, I thought, why not create an AI agent that connects to the Reddit API to do the research for me? That's how klerkAI came to life.
Future Plans:
I'm planning to expand klerkAI's capabilities to:
Check brand and project sentiment Perform political analysis Manage Google Sheets via WhatsApp Act as a personal email assistant via WhatsApp I'd love for you to try it out and share your feedback.
You can check it out here: https://klerkAI.com
Looking forward to your thoughts and suggestions!

53. Show HN: QwikDocs – a documentation tool for your editor
Author: atmospherejeans
Description: Hey everyone, I’ve been working on an app that is designed to make documenting software easier and more fluent from inside your editor.
It’s basically a VSCode extension that allows you to document your code in your editor; there is a web app too where you can add/manage projects.
The main differences between this tool and other ones I’ve seen are:
* Doesn’t require access to source control/git.
* Built to make documenting second nature (with the shortcuts above code).
* You do have a document with the AI option in the editor; however, the application doesn’t rely on AI documenting all of your code.
* Sync documentation with Notion, Confluence, etc. via markdown export.
Looking forward to feedback from the HN community! Would also love to hear about your experiences while building and documenting software and any other issues you’ve had during the process.
