1. Show HN: Bag of Tricks to 8x Faster Inference with ONNX+TensorRT
URL: https://dicksonneoh.com/portfolio/supercharge_your_pytorch_image_models/
Author: dnth
Description: In this post, I show how to speed up inference for PyTorch image classification models (from TIMM) using ONNX Runtime and TensorRT optimizations.
Key techniques covered:
- Converting PyTorch models to ONNX format
- Running inference with ONNX Runtime on CPU and GPU
- Leveraging TensorRT for maximum GPU performance
- Baking preprocessing into the ONNX model to eliminate overhead
The tutorial uses Hugging Face TIMM models as an example but can be applied to other PyTorch vision models as well. I’ve included code examples and benchmarks.

5. Show HN: Offline macOS app to convert Markdown documents
URL: https://docflex.app/
Author: dbvit
Description: Hi HN,
I’ve just launched DocFlex, an offline macOS app that converts Markdown documents into over 30 formats like PDF, HTML, EPUB, LaTeX, and more.
Why I built it:
As someone who frequently works with Markdown, I found it cumbersome to convert documents into different formats, especially when dealing with multiple files. Online converters weren’t ideal due to privacy concerns and the need for an internet connection. So, I created DocFlex to make the process seamless and entirely offline.
Key Features:
100% Offline: All conversions happen locally on your machine. Your documents are never sent to any servers. Batch Conversion: Convert multiple Markdown documents at once. 30+ Formats Supported: Export to PDF, HTML, EPUB, LaTeX, JSON, and many more. Native macOS App: Lightweight and focused solely on conversion without any unnecessary bloat (only installs basicTeX and pandoc). Download:
You can download it here: https://docflex.app/
I’d love to get your feedback and answer any questions you might have!

7. Show HN: I made a site to aid starting entrepreneurs manage their gigs
URL: https://myfounderskit.com/
Author: AnnaNBJ
Description: During our years managing a software house we have encountered many of the needs most of you have probably faced as well, such as:
- Understanding what financial metrics we need to constantly keep an eye on,
- Tracking the progress of profit, incomes and expenses,
- Managing our customer data and customer pipeline,
- Keeping track of inventory items and remembering to restock early on,
- Handling invoicing.
And there are many great tools out there to help with each and every one of these steps. But during our journey we felt that most of them are focused on really big business and extremely experienced managers, having a not so affordable price and a steep learning curve. That’s why we decided to create FoundersKit!
Please share any thoughts or feedbacks you may have :D

10. Show HN: Presidential polling with instant electoral results
Author: jkarneges
Description: Hi HN!
This is an experiment with low-friction, “fearless”, Internet-based polling. There is no authentication, only a captcha and restriction to US IP addresses. Congressional district is detected automatically. Selections can be changed at any time until the poll closes, kind of like a presidential caucus. Just tap to select. Tap again to change.
I built this after pondering about how polling (or even voting) could be improved through technology. Yes, digital voting is a tough space with trust issues. Maybe there are practical, partial solutions.
This is my third post. Earlier submissions didn’t perform well, probably because politics is a sensitive subject. However, this project is not political. It is about tech and process. I believe it’s an appropriate submission for HN and it ought to be interesting no matter your political leaning. Hopefully with this better framing there can be better discussion.
Another way of looking at it: if the poll results bother you, think about how improving polling/voting generally might help your cause.
Here are some topics to guide constructive discussion:
* Internet-based polling. Can we make this a routine thing? Would it be worthwhile? Abuse prevention?
* Internet-based voting. About time or never gonna happen?
* Augmenting the voting experience. We don’t have ranked choice voting, but maybe it could be simulated in advance of an election. Maybe an organization could act as a delivery agent for mail-in votes.
* The tech stack. This project uses a combination of boring (Django+Postgres) and shiny (Fastly edge pub/sub, captcha, etc). The database ought to be able to handle a few million participants. To get to a few hundred million I’d probably add more PG nodes and shard. Curious what others think about the database options for accurate+fast counting.
* Have fun with it! This isn’t a real election. If you want to VPN to an empty state to claim a bunch of electoral votes, go for it. I hope with enough participants the results would be mostly representative, though.
The poll will run every Monday afternoon/evening until Election Day. It’s designed to withstand a good bit of traffic so feel free to share it.

Description: I originally built a QR code generator as a resume project using Rust and I realized a web interface would make customization way easier.
This still generates the “data” using that rust library via wasm, but the rendering is all editable javascript to make an SVG or paint on an HTML canvas.
I was especially inspired by https://qrbtf.com which had some unique style options I had never seen before, which I ended up copying, and then I made some more.

13. Show HN: An app to improve touch typing by typing out whole books
Author: heydathan
Description: Hey everyone, Ive built an app where you can practive touch typing by typing out whole books.
I am a developer who recently learnt touch typing, I needed to practice typing to improve my muscle memory. Used monkeytype and keybr for a while and I got fed up by typing random words.
So i looked for platforms where I can type out books, because I am anyways typing, might as well read something meaningful while I am at it. I found some platforms, but i didnt like the experience, as since I am a backend web developer myself, I decided to build one which I can use and polish my frontend skills.
Please do try it out, ive spent months building it, any feedback on how to improve the app is really appreciated, and I hope you enjoy the app :)

14. Show HN: LANCommander v1.0.0 – Self-host your digital game library
URL: https://github.com/LANCommander/LANCommander/releases/tag/v1.0.0
Author: pathartl
Description: Last week I launched LANCommander v1.0.0 after about two years of development.
LANCommander is an open source digital game distribution platform. In essence, it’s a ways to self-host your own game library ala Steam, GOG, Epic, etc.
It originally started as a project to automate the distribution of games at a LAN party I co-host. We have about 24 peak players each session and there came a point where trying to get games to work ate more time than we actually spent playing games. The natural conclustion was to write my own launcher and server to distribute files across the network.
v1.0.0 represents the first version where the base features feel complete. Features include game installing, “cloud” saves, key allocation, and dedicated server management. I’ve been eating my own dog food along the way and really feel like I’ve been able to (mostly) take back control of my game library.
For more information about the project, you can check out the official documentation site at: https://docs.lancommander.app/

20. Show HN: PurePlates – A Recipe Scraping iOS App
URL: https://apps.apple.com/ca/app/pureplates/id6621180161
Author: CZubrecki
Description: Hey Everyone!
This is my first post on Hacker News, and I wanted to share my project with you! From a young age, I dreamed of becoming a chef, but life took me down the path of software engineering instead. Nevertheless, my passion for creating delicious meals has always remained close to my heart. This journey led me to seek out recipes to enhance my cooking skills, but I often found myself frustrated by the websites I encountered—ads everywhere, walls of text, and recipes that were difficult to follow.
That’s where PurePlates comes in. PurePlates allows users to share a recipe through their mobile browser or simply copy and paste the URL directly into the app. In an instant, you receive a scraped recipe that includes instructions, ingredients, and any available nutrition information. You can easily start cooking and follow along step by step, making the process much more enjoyable. Plus, if you find a recipe you love, you can add it to your favorites for quick access later!
As this is just an MVP, there’s still plenty of room for improvement, and I’m actively working on enhancing the extraction rate for recipes.
Thanks for reading, and keep hacking! Connor

Description: I wanted a better looking and better functioning mobile experience for Hacker News, so I created my own.
The two main improvements are:
- Larger touch targets for minimizing comments (faster reading)
- Dark mode (automatic)
I’m an app developer expanding to iOS, so I also built this in order to test using App Store Connect. The name is a play on Y Combinator and also doubles as a joke about some people’s opinions regarding redesigns. I figured that since I use this every day, someone else might find it useful! Open to feedback in the comments and I’ll naturally be building this out as I use it daily.

25. Show HN: Podverse – AI Superpowers for Podcasters
URL: #
Author: mdwelsh
Description: Hey HN, I’m excited to show off a project I have been building the last few months called Podverse — it automatically generates transcripts, summaries, and a chatbot from a podcast’s RSS feed, and makes it easy to embed AI features onto any website.
You can check it out at https://podverse.ai.
See it in action on an example podcast here: https://www.podverse.ai/podcast/omnibus
I’m a former engineer at Google and Apple, former CS prof at Harvard, and was a co-founder at Fixie.ai. I truly feel that LLMs are a revolution in our field, and I wanted to bring something to life that bridged between two deep interests of mine — AI and podcasts.
I’ve been listening a ton of podcasts lately, but it’s frustrating to find relevant episodes, or even content that I had listened to previously. I also know that podcasters want to take advantage of the latest AI tech to connect with and expand their audience, but they’re not usually equipped to bring all the pieces together. I wanted to build a complete, end-to-end solution for podcasters that is easy to use.
All you have to do is provide your RSS feed URL, and Podverse does the rest — automatically ingesting new episodes as you release them, generating transcripts and summaries, identifying speakers, and populating a custom chatbot that knows about all of the content of your podcast.
I built the site from scratch over the last few months (in my copious spare time!). It’s built entirely using Next.js deployed on Vercel — no backend servers beyond Vercel’s server components and API handlers. For running background tasks, like podcast ingestion and transcription, I used Inngest, which fills a big gap in the Next.js stack. Deepgram is used for ASR, which is fast, affordable, and very high quality. Supabase handles the storage, including the vector database (using pgvector). Auth is done with Clerk, which was super easy to integrate. Happy to answer any questions about the stack.
I’d love to get your feedback, and especially hear from podcasters to learn more about what features you’d like to see. Thanks!

27. Show HN: Jikken – open-source API testing supporting source control and CI/CD
URL: https://github.com/jikkenio/jikken
Author: jikkenio
Description: Greetings,
What is Jikken? Jikken is an open source CLI tool for automated API testing, built in Rust!
The tool was originally developed to help validate complex data APIs used for analytics dashboards while integrating well with source control and CI/CD platforms. When troubleshooting API endpoints, I found my team either messing with gluing cURL/JQ/Diff together, or writing JavaScript in tools like Postman to accomplish essentially the same thing. My goal was a CLI tool which read small test definitions and could execute them seamlessly from both a local machine or in a CI/CD pipeline.
Jikken supports things like automatic comparing of different API endpoints (across release versions or environments), JSON filtering and variable extraction (passing variables from one call to the next), injecting data files, input data generation (fuzz testing with primitive types like ints/strings or higher level types like email addresses or names), or validating against heuristics instead of exact values (expect response values to contain these things, or have numbers within a certain range, etc).
Jikken also supports global variables and secrets, has built in mechanisms such as cookie support mimicking browser functionality, automatic test generation from openapi specs, junit test output for integrating into other tools/platforms, etc.
Originally, the tool was for me and my team to use at work. Since then I’ve open sourced it, and brought on some cofounders to launch Jikken as a B2B SaaS. Our goal is to maintain the tool, expand the capabilities, and to build a platform which is useful for companies.
While there are many Postman-like competitors out there, our intention is to have a happy path for both open source and paid customers. Tests are files that you own/control. The test runner tooling is entirely free and open source (written in Rust). We don’t require you to make an account, nor do we collect any data or telemetry from you. You can use the tooling locally, on servers, or even with CI/CD for free.
What Jikken provides as a bootstrapped SaaS company, is a platform for metrics, monitoring, and alerts of test execution across projects and environments. If, and only if, you configure an API key in the tool, you can stream telemetry back to our platform. This allows you to view real-time dashboards of all your test runs across environments and projects, metrics around performance characteristics of your API endpoints, and setup alerts to notify you in slack/teams/etc based on criteria you define. Customers can also choose to execute tests from our platform instead of running them on their own infrastructure.
As we know not all users are comfortable with a CLI, we are working to expand our free and open source tooling to provide a GUI client that is tailored for working with our files, which runs on the same engine as the CLI tool. This will also be completely free and open source, not require making an account or streaming any telemetry to us. Privacy matters.
We are aware that there are many other tools out there and we hope to have our tools be worth the effort for people to switch. We’re actively working on expanding the documentation and examples on our site. As always we’d love any feedback you can provide. Thank you!

Description: Hello everyone,
I’ve built a simple macOS app for chatting with models downloaded by Ollama - https://github.com/sheshbabu/Chital
It’s written in Swift, consumes less memory and loads fast.
It has these features:
* Support for multiple chat threads
* Switch between different models
* Markdown support
* Automatic chat thread title summarization
It’s my first time working with Swift and Xcode, and it has been an interesting journey. The performance of the application is a big plus when building native apps, but I wonder if I’ll be able to add features like document processing, RAG and other capabilities that are easy to implement using Python.
Give it a try and let me know what you think :)

URL: #
Author: tankots42
Description: Hey HN! We’re Tanay and Sahaj from the Wispr Flow team (https://flowvoice.ai). Today, we’re officially launching Flow: a Mac dictation app that lets you speak naturally and writes in your style, in every application — with auto-edits, command mode, and over 100 languages.
Watch a quick 90 second demo here (feat. Steve Wozniak): https://www.loom.com/share/2fd33f10407947b08c6d688398d8679e
PS: Last week, Rahul Vohra from Superhuman called it “the best AI product I’ve used since ChatGPT ”, and hearing it honestly made my day.
[The founding story]
Ever since I watched the first Ironman movie in 2008 at age 10, I’ve wanted to build Jarvis. It drove me to pull my first all-nighter and teach myself code.
16 years later, we’ve found a way to make a voice experience delightful for all-day use. And there’s no one else I’d build this with than my college roommate and closest friend, Sahaj.
Our vision is to make voice interfaces useful (so you trust them) and ubiquitous (so you can use them everywhere). This is how we can move from screen-first to voice-first technologies and build a future where we aren’t stuck looking at our phones all day.
[Using Flow is super simple]
- Download Flow for Mac (Apple Silicon only - others coming soon)
- Press and hold [Fn] to start speaking in any app
- Release [Fn] to enter text
[What users love Flow for]
- Developers using Cursor / Claude / ChatGPT: Speak with AI assistants faster than typing.
- Professionals breezing through their inbox: Flow accurately captures names and formats your emails and Slack messages.
- Students chatting with AI and finishing assignments even faster: We have a special student discount.
- Product Managers drafting PRDs and sharing thoughts: Flow turns your rambles into clear ideas.
- Parents with busy lives: Time is precious. Every second you save writing is an extra second you have for family.
- Tech-lovers who want to use voice with every AI tool
What makes Flow different is we designed our models for zero-edit messages - the metric that users really care about, instead of ‘word error rates’. For comparison, Apple / Google dictation is <5% zero-edit messages (i.e., 95% of the messages, you have to correct at least one word). Flow today is 50-70% of the messages being zero-edit, based on the use case.
After six months of sleepless nights with our team, we had our first set of users who organically started using Flow more than their keyboards. Today, that’s a large fraction of our users. Still, we have a long way to go, and we’re just getting started.
Would love for you to try it out at https://flowvoice.ai (web playground and desktop app). You can keep using the free version (2000 word / week limit) or upgrade to the Pro version starting at $12 / mo (annually). For the HN community, use the HNLAUNCH promo to get 33% off (or 4 months free on the annual plan)
PS: A massive shoutout to our thousands of beta users who’ve showered us with love and feedback over the last few months. We wouldn’t be here without you.
Our dream is to create a world where interacting with technology feels as natural as interacting with people. I’d love your help to make this a reality. We’d love to hear your ideas and comments with voice intelligence! Bonus points if you write your comment with Flow ;)

40. Show HN: A macOS app to prevent sound quality degradation on AirPods
URL: https://apps.apple.com/us/app/crystalclear-sound/id6695723746?mt=12
Author: mrtksn
Description: Right, here’s the thing: If you are using AirPods(or any Bluetooth headphones with a mic in fact) on Mac and something activates the mic(i.e. you Shazam a song), the sound will be interrupted momentarily and will return in very low quality. This is happening because Bluetooth can’t handle both way high quality streaming and the bandwidth is decreased to make it work.
It’s a known issue and here’s what Apple recommends to fix it: https://support.apple.com/en-hk/102217
Most of the time(unless you are on a Mac Mini/Studio/Pro), you have much higher quality microphones built in, so in most use cases, you want to hear from your AirPods but be heard from your internal microphone, which means if every time you connect your AirPods and go into the settings and set the default input device as the internal mic, you won’t have sound quality degradation on mic activation, and if you use your mic to talk to people or record something, you will have better sound quality too.
Based on this observation, first I tried to create a script or some automation that can do it for me but found out that it can be clunky or needlessly complex.
Here’s someone who used this approach to fix this issue: https://www.dermitch.de/post/macos-force-microphone-when-usi…
Anyway, I decided to take the “build your app for that” route and created this app and called it CrystalClear Audio which doesn’t involve any technical setup to use. Making it was also not as easy I hoped, I was expecting this to be a half an hour project but ended up filing bug reports with Apple because some API wasn’t behaving as expected or mysterious things were happening when using it(like phantom device changes).
After spending that much time with all this, I decided to publish it on Mac AppStore and after too many rejections(all my mistakes) I got it published: https://apps.apple.com/us/app/crystalclear-sound/id669572374…
The app is not free but comes with a free trial. I decided to go with a very cheap subscription model because I suspect further development might be needed as bugs emerge or API behavior changes. I know its a hated business model but IMHO it’s better than ads or tracking of any sort to justify the work done. It’s not free because supporting a free app is just as hard as supporting a paid one and it’s not one time payment because I don’t know what would the right price be for supporting an app for years to come and still have people willing to pay for it.
I hope other people find this useful and if you do, you can support by upvoting on Producthunt so even more people can find it sueful: https://www.producthunt.com/posts/crystalclear-sound
PS: the app is also useful for quickly switching between giving the sound out of the laptop speakers and the headphones, I ended up using that quite often.

42. Show HN: Secure.py – Simplify HTTP Security Headers for Python Web Apps
URL: https://github.com/TypeError/secure
Author: cak
Description: Hi HN,
I’m excited to share a major update to secure.py, a Python library designed to make adding essential HTTP security headers to web apps easier than ever. This release is a complete rewrite, leveraging modern Python 3.10+ features to enhance usability and performance.
Why secure.py?
Adding headers like Content Security Policy (CSP), HSTS, and X-Frame-Options is crucial for protecting web applications from attacks like XSS and clickjacking. However, managing these headers across different frameworks and ensuring adherence to best practices can be cumbersome. secure.py removes that friction by providing:
- Out-of-the-Box Security Presets: Apply BASIC or STRICT security configurations with a single line of code.
- Full Customization: Take control over headers like CSP, HSTS, X-Frame-Options, Referrer-Policy, and more to tailor security to your app’s needs.
- Multi-Framework Support: Works with popular frameworks including Flask, Django, FastAPI, Starlette, and more—both synchronous and asynchronous.
- Modern Pythonic Design: Utilizes Python 3.10+ features like structural pattern matching and improved type hinting for cleaner and more efficient code.
- No External Dependencies: Lightweight and easy to include in any project.
- Best Practice Compliance: Follows recommendations from the OWASP Secure Headers Project and MDN Web Docs for robust security.
Requirements:
- Python 3.10 or higher
If you’re tired of manually adding security headers and worrying about consistency, give secure.py a try. It’s open source and designed to help developers add the kind of security that every app should have by default.

43. Show HN: Real-time Network IN/OUT and Syscall monitoring using eBPF
URL: https://github.com/nullswan/bpfsnitch
Author: swanYC
Description: Hi HN,
I just released bpfsnitch, an open-source, real-time monitoring tool for Linux systems and Kubernetes clusters. Inspired by the need for deeper security insights without adding unnecessary layers, bpfsnitch leverages eBPF technology to monitor system calls and network activities at the kernel level.
The aim is to make security more accessible by providing a tool that’s easy to deploy and offers immediate value. Whether you’re a DevOps engineer, a security professional, or someone interested in learning more about eBPF and kernel-level observability, I believe bpfsnitch can be a valuable resource.
Feel free to check out the repository, give it a star if you find it useful, and join the discussion. I will be here to answer any questions and would love your feedback!
Looking forward to your thoughts and contributions!
