V2.0 of Open SaaS, a free, open-source SaaS boilerplate starter is here
I launched Open SaaS about a year and a half ago and surprisingly it’s become one of the most popular free SaaS boilerplate starters on github (https://github.com/wasp/open-saas). After 2 years of work total, I’m pleased to launch what I’m calling “Open SaaS v2.0”. Here’s a breakdown of all the features and updates I’ve made to it over time: * New Big, Shiny Things for v2.0 * - Complete redesign with Shadcn UI for a modern and consistent look (themeability coming soon...). - Script that autogenerates an LLM-friendly version of the documentation…
In plain words
Open SaaS v2.0 is a free, open-source SaaS boilerplate starter built with modern tools like Shadcn UI and Wasp. It provides developers with a complete foundation for building SaaS applications, including built-in authentication without third-party dependencies, payment integration with Stripe, Zod validation, and documentation. The project includes an autogenerated LLM-friendly documentation version and prioritizes open-source tools throughout. It is designed for developers looking to launch SaaS products without building infrastructure from scratch.

In the maker’s words, at launch
I launched Open SaaS about a year and a half ago and surprisingly it’s become one of the most popular free SaaS boilerplate starters on github (https://github.com/wasp/open-saas). After 2 years of work total, I’m pleased to launch what I’m calling “Open SaaS v2.0”. Here’s a breakdown of all the features and updates I’ve made to it over time: * New Big, Shiny Things for v2.0 * - Complete redesign with Shadcn UI for a modern and consistent look (themeability coming soon...). - Script that autogenerates an LLM-friendly version of the documentation https://docs.opensaas.sh/llms-full.txt. - Added Zod validation for webhook payloads. * Main Features * - 100% open-source repo w/ a focus on open-source tools when possible. - Auth that you own (no 3rd party services): email, google, github, discord... - Full Payments Integration: easily swap out Stripe for Lemon Squeezy or Polar (coming soon!). - Full-stack typesafety on top of React, NodeJS, Prisma. - Admin dashboard w/ revenue and site analytics (Google or Plausible) - OpenAI API & AWS S3 integrations. * New Features* - Added Lemon Squeezy as payment provider option (Polar and Paddle in the works!). - Enhanced file uploads with progress bars and validation. - Added a generic cookie consent banner (if you need one). - Integrated Playwright for end-to-end testing. - Added a 404 page. * Fixes & Improvements* - Upgraded Wasp (React/NodeJS/Postgres) framework to v0.17.0. - Upgraded AWS and OpenAI SDKs to their newest-ish versions. - Tightened S3 CORS configuration for better security. - Improved payment webhook logic. - Made UI components more consistent (e.g., controlled switches). - Fixed various styling issues, including dark mode inconsistencies. - Improved error handling and validation across the app. * Refactoring & Code Organization* - Major "vertical reorganization" of the codebase for improved modularity (auth, payments, users, file-upload). - Significant refactoring of user management pages and queries. - Refactored to use prisma transactions for safer DB mutations. - Cleaned up and simplified various parts of the codebase. * Docs & Content* - Updated documentation for deployment, installation, and new features. - Added a customization checklist. There have been a slew of paid SaaS boilerplate starters popping up since we started, but Open SaaS will stay free and open-source forever. So if you’re interested in becoming a contributor, or just wanna add a suggestion to the roadmap, feel free to create an issue https://github.com/wasp-lang/open-saas/issues.

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

I built the world's most impractical 1000-pixel display and anyone in the world can draw on it. It draws a single pixel at a time and takes 30-60 minutes to complete a single image. Anyone can participate in the project by voting for the next image to be drawn, and submitting images. https://kilopx.com/

Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…

I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!

For HTML Day 2025 [1], I made a web service that displays the current sky at your approximate location as a CSS gradient. Colours are simulated on-demand using atmospheric absorption and scattering coefficients. Updates every minute, without the use of client-side JavaScript.
