Lumi – AI apps and websites builder (base44/lovable alternative)
Hi HN — we’re the team behind Lumi (lumi.new). Lumi is an all-in-one platform to build and launch websites or lightweight apps simply by chatting—no code needed to write, no external services needed to integrate. We’re a 10+ person team. What’s UNIQUE: ANYWHERE: Multi-country language support out of the box (create & maintain multiple locales in one project) ANYONE: With built-in Database + Sign-In + more internal tools coming soon, anyone can achieve anything without technical stuff being barriers ANYTIME：No waiting list! Works right now to bulid CRM system, e-commerce portal, photo -…
What it does
In the maker’s words, at launch
Hi HN — we’re the team behind Lumi (lumi.new). Lumi is an all-in-one platform to build and launch websites or lightweight apps simply by chatting—no code needed to write, no external services needed to integrate. We’re a 10+ person team. What’s UNIQUE: ANYWHERE: Multi-country language support out of the box (create & maintain multiple locales in one project) ANYONE: With built-in Database + Sign-In + more internal tools coming soon, anyone can achieve anything without technical stuff being barriers ANYTIME：No waiting list! Works right now to bulid CRM system, e-commerce portal, photo - sharing platform and more In DEVELOPMENT: email sending, file storage, Stripe payments, and more! Closest analogy is Base44, but Lumi is leaning into i18n + bundled DB/auth so founders can go live in multiple markets without extra setup. And Lumi performs far better in achieving more stunning page effects and handling more complex logic. We’d love feedback on the localization workflow, DB/auth defaults, and what else would make Lumi more useful on day 0. (Disclosure: creators here, happy to answer questions!)

Hello HN! The day has finally come to stop adding features and start sharing what I've been building the last 5-6 months. It's a bit of CrewAI, OpenDevon, LangFuse/Cloud all in one, providing devs who prefer TypeScript an integrated framework thats provides a lot out of the box to start experimenting and building agents with. It started after peeking at the LangChain docs a few times and never liking the example code. I began experimenting with automating a simple Jira request from the engineering team to add an index to one of our Google Spanner databases (for context I'm the…

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.
