2. Show HN: Lightpanda, an open-source headless browser in Zig
URL: https://github.com/lightpanda-io/browser
Author: fbouvier
Description: We’re Francis and Pierre, and we're excited to share Lightpanda (https://lightpanda.io), an open-source headless browser we’ve been building for the past 2 years from scratch in Zig (not dependent on Chromium or Firefox). It’s a faster and lighter alternative for headless operations without any graphical rendering.
Why start over? We’ve worked a lot with Chrome headless at our previous company, scraping millions of web pages per day. While it’s powerful, it’s also heavy on CPU and memory usage. For scraping at scale, building AI agents, or automating websites, the overheads are high. So we asked ourselves: what if we built a browser that only did what’s absolutely necessary for headless automation?
Our browser is made of the following main components:
- an HTTP loader
- an HTML parser and DOM tree (based on Netsurf libs)
- a Javascript runtime (v8)
- partial web APIs support (currently DOM and XHR/Fetch)
- and a CDP (Chrome Debug Protocol) server to allow plug & play connection with existing scripts (Puppeteer, Playwright, etc).
The main idea is to avoid any graphical rendering and just work with data manipulation, which in our experience covers a wide range of headless use cases (excluding some, like screenshot generation).
In our current test case Lightpanda is roughly 10x faster than Chrome headless while using 10x less memory.
It's a work in progress, there are hundreds of Web APIs, and for now we just support some of them. It's a beta version, so expect most websites to fail or crash. The plan is to increase coverage over time.
We chose Zig for its seamless integration with C libs and its comptime feature that allow us to generate bi-directional Native to JS APIs (see our zig-js-runtime lib https://github.com/lightpanda-io/zig-js-runtime). And of course for its performance :)
As a company, our business model is based on a Managed Cloud, browser as a service. Currently, this is primarily powered by Chrome, but as we integrate more web APIs it will gradually transition to Lightpanda.
We would love to hear your thoughts and feedback. Where should we focus our efforts next to support your use cases?

3. Show HN: Onit – open-source ChatGPT Desktop with local mode, Claude, Gemini
URL: https://github.com/synth-inc/onit
Author: telenardo
Description: Hey Hackernews- it’s Tim Lenardo and I’m launching v1 of Onit today!
Onit is ChatGPT Desktop, but with local mode and support for other model providers (Anthropic, GoogleAI, etc). It's also like Cursor Chat, but everywhere on your computer - not just in your IDE!
Onit is open-source! You can download a pre-built version from our website: www.getonit.ai
Or build directly from the source code: https://github.com/synth-inc/onit
We built this because we believe: Universal Access: AI assistants should be accessible from anywhere on my computer, not just in the browser or in specific apps Provider Freedom: Consumers should have the choice between providers (anthropic, openAI, etc.) not be locked into a single one (ChatGPT desktop only has OpenAI models) Local first: AI is more useful with access to your data. But that doesn't count for much if you have to upload personal files to an untrusted server. Onit will always provide options for local processing. No personal data leaves your computer without approval Customizability: Onit is your assistant. You should be able to configure it to your liking Extensibility: Onit should allow the community to build and share extensions, making it more useful for everyone.
The features for V1 include: Local mode - chat with any model running locally on Ollama! No internet connection required Multi-provider support - Top models for OpenAI, Anthropic, xAI, and GoogleAI File upload - add images or files for context (bonus: Drag & drop works too!) History - revisit prior chats through the history view or with a simple up/down arrow shortcut Customizable Shortcut - you pick your hotkey to launch the chat window. (Command+zero by default)
Anticipated questions:
What data are you collecting? Onit V1 does not have a server. Local requests are handled locally, and remote requests are sent to model providers directly from the client. We collect crash reports through Firebase and a single "chat sent" event through PostHog analytics. We don't store your prompts or responses.
How to does Onit support local mode? For use local mode, run Ollama. You can get Ollama here: https://ollama.com/ Onit gets a list of your local models through Ollama’s API.
Which models do you support? For remote models, Onit V1 supports Anthropic, OpenAI, xAI and GoogleAI. Default models include (o1, o1-mini, GPT-4o, Claude3.5 Sonnet, Claude3.5 Haiku, Gemini 2.0, Grok 2, Grok 2 Vision). For local mode, Onit supports any models you can run locally on Ollama!
What license is Onit under? We’re releasing V1 available on a Creative Commons Non-Commercial license. We believe the transparency of open-source is critical. We also want to make sure individuals can customize Onit to their needs (please submit PRs!). However, we don’t want people to sell the code as their own.
Where is the monetization? We’re not monetizing V1. In the future we may add paid premium features. Local chat will- of course- always remain free. If you disagree with a monetized feature, you can always build from source!
Why not Linux or Windows? Gotta start somewhere! If the reception is positive, we’ll work hard to add further support.
Who are we? We are Synth, Inc, a small team of developers in San Francisco building at the frontier of AI progress. Other projects include Checkbin (www.checkbin.dev) and Alias (deprecated - www.alias.inc).
We’d love to hear from you! Feel free to reach out at contact@getonit dot ai.
Future roadmap includes: Autocontext - automatically pull context from computer, rather than having to repeatedly upload. Local-RAG - let users index and create context from their files without uploading anything. Local-typeahead - i.e. Cursor Tab but for everywhere Additional support - add Linux/Windows, Mistral/Deepseek etc etc. (maybe) Bundle Ollama to avoid double-download And lot’s more!

4. Show HN: I recovered one of my earliest ZX-Spectrum games from an audio cassette
URL: #
Author: codeguppy
Description: Recently, I managed to recover some of my earliest work from the ZX Spectrum era from an old audio cassette.
It is a mini-game, that I created as a teen, called "Atomix," written in BASIC with a mix of Z80 assembly — some of which I coded myself, while other parts were disassembled from existing games. I put the game in an modern emulator and recorded a screencast. See the video in my linkedin post:

7. Show HN: Snap Scope – Visualize Lens Focal Length Distribution from EXIF Data
URL: https://snap-scope.shj.rip/?lng=en
Author: kan02134
Description: Hey HN, I built this tool because I wanted to understand which focal lengths I actually use when taking photos. It's a web app that analyzes EXIF data to visualize focal length distribution patterns.
While it's admittedly niche (focused specifically on photography), I think it could be useful for photographers trying to understand their lens usage patterns or making decisions about lens purchases.
Features: Client-side EXIF data processing (no server uploads/tracking) / Handles thousands of photos at once / Clean visualization with shareable summaries
This tool supports most RAW formats, but you might occasionally encounter files where EXIF extraction fails. In such cases, converting to more common formats like JPEG usually resolves the issue.

URL: https://www.youtube.com/watch?v=yJ-ovZGp-D0
Author: firepegasus11
Description: Hi, my name is Aditya, and I’m working on teaching math through a mission-based approach. I’ve provided a video link that serves as a trailer for one of my challenges. Here’s how it works:
1. Understand the Challenge: In this mission, the goal is to design a UAV that can fly between mountains to avoid enemy radar.
2. Create Your Solution: Students create a basic design—either on paper or using Blender—while doing calculations. Topics like algebra, geometry, etc., come into play. Once ready, they upload their design.
3. AI Analysis: The AI analyzes the design, runs a simulation, and provides results in the form of expected output and points.
The aim is simple: give students a project to work on so they can practice math while also learning about aerospace and science.
I’m looking for feedback and beta users to test this approach. Any help or suggestions would be much appreciated!
About me: I’ve been working on game-based learning for the past three years. I’ve built a few games to teach topics like trigonometry and algebra, and I’m constantly trying to push the boundaries of how students engage with STEM topics.

9. Show HN: Vigilant - Blazing fast dev-friendly logs
URL: https://www.vigilant.run/home
Author: benshumaker
Description: Hey HN! We're Ben and Izak, the cofounders of Vigilant. Vigilant is a lightweight tool for managing structured logs. It lets you centralize your logs, search them, and create alerts.
We used Cloudwatch for logs on our last product, and it was quite painful. Even basic searches felt tedious. We’ve used dedicated observability tools at past jobs, but most of them have a steep learning curve and require widespread integration (and some still feel clunky). With Vigilant, we're focused on making logs feel fast and simple.
We operate at the application layer with an sdk. We're trying a unique optional feature that automatically reads stdout. It lets you capture existing console.log and print statements. And if you want custom log attributes, you can add them with middleware. This approach minimizes the impact on your codebase, and it's easy to understand. But it only gets application logs; still valuable, though we may need to expand to system logs later.
A while ago, we heard the team behind Cursor follows the guideline “Fast is fun.” It really resonates with us. We think it could extend to everything in the developer workflow, not just the IDE. So in our dashboard, we optimize for speed. The first page you open is your logs. We present logs like a spreadsheet, with rearrangeable columns. You can search without writing queries, and you can add filters with one click. Our queries themselves are pretty fast (Clickhouse under the hood). Though we still need to do better indexing to make searches even faster.
For background context, we actually pivoted to Vigilant. We were part of YC S23 and our original product was a webgl-based design tool and website builder - https://news.ycombinator.com/item?id=41436338. It’s dead now. Repaint had a master plan, a beautiful UI, awesome technology… and no users.
So honestly, we’re trying to avoid a big master plan with Vigilant. We’re just trying to listen and learn. We already have more users (big win!). And we’ve noticed that as we optimize the experience, they use it more. Seems like developers enjoy tools that don't disrupt their workflow. We're interested to see how far we can take that.
We’re still early and we’d love ideas and feedback. So if Vigilant seems helpful, please try it!

12. Show HN: Prism – An AI-Driven Generative Art System That Evolves over Time
URL: https://github.com/P-R-I-S-M-PROJECT/P.R.I.S.M
Author: Pushing_Prism
Description: Hey HN,
I’m excited to share PRISM, an open-source system we’ve been building that fuses multiple AI models (OpenAI, Anthropic, and FAL API) with Processing to create evolving geometric art and static images. The idea came from our fascination with how AI can generate new forms but often lacks a memory or evolutionary approach. PRISM aims to solve that by “remembering” past successes and failures and then adapting its creative approach over time + useful for automating batches and variations of specific styles of techniques with prompt adjusting.
Key Features:
- Multi-model AI Generation: Code and images produced by GPT-like models, Claude variants, and FAL Flux.
- Evolutionary Memory: Each pattern generation is analyzed; successful techniques become more likely in future generations.
- Processing Integration: Animations are rendered via Processing on Windows (with plans to expand cross-platform).
- Interactive Menu System: Easy to navigate, choose models, generate single/batch patterns, or run continuous mode.
- Roadmap for Growth: We plan to add a web interface, advanced pattern analysis, real-time collaboration, and more.
Tech Stack & Challenges:
- Python for the orchestration, hooking into each AI API (OpenAI, Anthropic, FAL).
- Processing 4.0+ for rendering animations.
- Evolutionary Approach: We track performance metrics (visual complexity, motion quality, aesthetic evaluation) to shape future generations.
- We had to tackle issues like ensuring code output from GPT/Claude is valid Processing code, managing timeouts, and orchestrating multiple model calls in parallel.
Why We Built This: We wanted to see if AI can become a “creative collaborator” instead of just a single-shot generator. By incorporating an evolving memory and multiple model personalities, we aim for more diverse and interesting results.
How to Try It:
- Clone the repo:
git clone <a href="https://github.com/P-R-I-S-M-PROJECT/P.R.I.S.M.git">https://github.com/P-R-I-S-M-PROJECT/P.R.I.S.M.git</a> - Install requirements (
pip install -r requirements.txt) and set your.envwith API keys. - Run
python prism.pyon Windows with Processing installed (roadmap includes broader OS support soon).Questions for HN:
- Does this “multi-model + evolutionary” approach resonate with you? How might we improve it?
- Any suggestions for better pattern analysis or new AI integrations?
- Feedback on user experience or installation process?
GitHub Link: [https://github.com/P-R-I-S-M-PROJECT/P.R.I.S.M]
Thanks for checking it out! I’ll be around to answer any questions or hear your thoughts on making this a better tool for the creative coding community.

15. Show HN: Signal.fyi – Are You Managing the Hidden Costs of Public Docker Images?
Author: kcrane3576
Description: Hey HN, I built signal.fyi to address a problem I’ve seen firsthand: managing public Docker images isn’t as “free” as it seems. From tracking vulnerabilities to ensuring compliance, the hidden costs add up—especially for small teams without the resources of larger organizations.
What signal.fyi Does:
- Daily Scans: Automatically checks your public Docker images for vulnerabilities and parent image updates.
- Enriched Pull Requests: Summarizes vulnerabilities and parent image changes right in your PRs, helping teams isolate risks and streamline reviews.
- Public Dashboards & Reports: Provides no-login-required, shareable compliance reports for stakeholders and audits.
Why It Matters: Managing public Docker images manually is time-intensive. Based on research (inspired by Chainguard’s Report: https://get.chainguard.dev/true-cost-of-vulnerability-manage...), teams can spend thousands of hours annually on CVE management and compliance prep. Signal.fyi automates these processes to:
- Improve visibility into security risks.
- Track changes to your parent Docker image—a critical yet often overlooked metric.
- Create an audit trail to align with frameworks like NIST’s Secure Software Development Framework (SSDF).
Who It’s For: Teams that manage source code via github and rely on public Docker images and want to reduce security risks. Organizations looking to simplify compliance while improving transparency.
Why Now: We’ve written about the hidden costs of managing public Docker images—are you prepared to address them? You can read more here: https://www.lftsolutions.com/are-you-managing-the-hidden-cos...
Try signal.fyi: Setup takes under 5 minutes, and you’ll get actionable insights within 24 hours: https://github.com/marketplace/www-signal-fyi
I’d love your feedback—what resonates with you, and how can signal.fyi solve your challenges better?

Previously I'd used Duolingo to learn Japanese, but failed spectacularly when I actually spoke with my roommate from Tokyo.
Now, after OpenAI improved their Realtime audio model in December and reduced pricing, I spent my entire winter break building.
So how does it work? Just choose a daily topic and converse with the AI model:
(1) Didn't catch a phrase? Double tap to reveal a transcript.
(2) Couldn't understand? Double tap for translations powered by Google.
(3) Can't recall that intricate Chinese/Japanese character? Just tap for an integrated dictionary.
(4) Then, review your saved words with spaced-repetition, just like an Anki deck.
Try it for free, and let me know your thoughts :) ありがとうございます！(Thanks!)

21. Show HN: I Built a Tool that Detects If a Voice is AI-Generated. 94% Accuracy
URL: https://github.com/zo9999/deepfake-audio-detector
Author: zuriobozuwa
Description: Hello from San Francisco!
I built this tool in 2023 that detects whether or not a voice is AI-generated.
It takes an audio clip of somebody speaking as input, and gives a binary classification ('human' or 'AI') as output.
I tested it tonight (2025) on some ElevenLabs clips and it still works!
I built it using a fairly simple Convolutional Neural Network (CNN).
Essentially, we pre-process the audio to produce a Mel Spectrogram, then we use the CNN to do image classification on the spectrogram.
The Jupyter notebook file that I wrote to train the model is in the 'model' dir, but if you wanna just use the tool, there's a python script in the root directory of the project.
I trained the model on a Paperspace (acquired by DigitalOcean) cloud server with one GPU.
Check it out!

Description: Hi HN, I'm excited to introduce LACS, a simple standard for classifying digital assets as Human-Made, AI-Assisted, or AI-Generated. With the rise of AI in creative spaces, it's becoming increasingly important to understand the origin of assets. LACS is simple, but it's a first step towards helping creators communicate this transparently. Ultimately, it's about consumers knowing what they buy - some don't want "AI generated junk" (not my words, I'm neutral).
It's easy to use – just add a tag like LACS-H to your asset file's metadata or on its listing page in asset marketplaces. I've also created badges for visual identification. Would love to hear your feedback, or your pull request with improvements!

41. Show HN: I built a way to 50-100x engagement on X
URL: https://www.veed.io:443/view/52b11b3b-f54c-4bb3-9942-a52476b75acc
Author: desleong
Description: It rewards community members for engaging with your X's posts. Gives them coins which they can use to redeem stuff in the store (eg. free subscriptions, discounts, merch, etc).
Did it for youtube, LinkedIn, FB and IG too. Surprisingly, youtube API is the most restrictive to work with. X is the easiest - you just need to pay them (no surprises).
Added a penalty system that deducts a multiplier of the coins awarded if someone tries to game the system (eg. remove a like).
Might be interesting to see how people use this to actually use their community to grow their socials. Sometimes i look at discord communities (esp web 3) and feel that they feel kinda wall-ed up within discord - like you can't use it much to power much of your businesses. Heck you don't even know who signed up beyond their username.
Oh and yeah this is actually built on a community building platform that is like discord + slack, but with a focus on businesses use cases (eg. white-labelling, APIs, LLMs, etc).

46. Show HN: Travel Easy – A Simple Tool for Planning Road Trips
URL: https://www.hibernation.dev/
Author: ositowang
Description: Hi everyone, Osito here!
I love road trips and take them often, but I’ve always found the initial planning stage to be a bit time-consuming—it can take hours of browsing to get everything sorted. Over the weekend, I decided to tackle this problem and built a tool called Travel Easy.
The app is currently in its MVP (Minimum Viable Product) stage. I’ve shared it with my inner circle, received some encouraging feedback, and now I want to share it with you all on Hacker News.
Travel Easy aims to simplify the planning process, saving you time and effort. I’d love for you to try it out and share your thoughts, issues and feedback.
This is just the beginning—I have plenty of ideas and features I’d like to add to make it an even more useful tool. If people find it valuable, I’d be excited to evolve Travel Easy from an MVP into a fully-fledged product.
Check it out and let me know what you think.

47. Show HN: AI-Powered eBook Reader
URL: https://apps.apple.com/ca/app/bookread-ai-reader-insights/id6737578649
Author: frankt002
Description: Hi everybody , my name is Frank, co-founder of BookRead AI
One year ago, I was reading the Genealogy of Morals by Friedrich Nietzsche, but I simply could not understand what Nietzsche was writing, until I started taking pictures of each page and using ChatGPT to explain it. I had to do this for every single page . Even though it took so much effort to do it, the value of reading alongside AI was so high that I finished the entire book this way. I even wrote a Tweet to beg Jeff Bezos to build an AI-powered Kindle so that I don't have to do that anymore . One year has passed, no one has made anything like it, so I decided to make it happen for the world.
Introducing BookRead, an AI-powered E-Reader that make reading effortless and helps you learn more from books.
Some Key features of BookRead AI: AI Explain: Highlight any phrase or sentence, and AI will explain it in simple terms, within the context of the book. You can also ask questions like chatting with ChatGPT. AI Definition: Select text, and AI detects it’s a request for a definition, providing context-based meanings, not just dictionary definitions. Reword & Translate: Reword sentences or translate them into any language you prefer for better understanding. Knowledge Retention: AI generates flashcards at the end of each chapter to help reinforce learning and improve retention, based on Andrew Huberman's self-testing method. Reading Tracking & Library: Track your reading progress, set daily goals, maintain streaks, and access a free book library to stay motivated.
We're very excited about how AI can help us read. There are many interesting AI use cases that we're building for reading, such as chatting with the whole book, generating discussions based on the context, text to speech...
Btw, we just launched on product hunt, would mean the world if you can support us here: https://www.producthunt.com/posts/bookread

48. Show HN: Vole Machine ISA Simulator

Author: faresahmed
Description: Just sharing this project [0] I've worked on a while ago, it's not that interesting but I was proud of making it. It has a CLI and a GUI that is done with Dear ImGui and includes an instruction editor, memory and registers viewer, and a canvas that is manipulated with an extra instruction made specifically for the GUI!
This is not my first attempt at a virtual machine implementation, I've done the popular LC-3 VM before [1], check it out if you're interested to see Rust code rather than C++ ;)
