👋 Hey everyone - I’m Etai, I’m 16, love to code, and most importantly, I’m the creator of Gelt.dev.
I’m super excited to finally share what I’ve been building over the past few months!
tl;dr: Gelt.dev is like Bolt / v0 / Lovable, but our agent is built to be truly autonomous. It doesn't just execute a pre-planned script; it actively reasons, debugs its own code, and self-corrects in real-time to build your app. This results in more complex, production-ready applications with significantly fewer errors - all while being 40% cheaper than competitors.
Here’s what makes Gelt special:
🕵️♀️ Our own AI agent - On par with Claude Code and Codex, optimized for full-stack generation.
⚙️ Zero setup - Build, test, and deploy apps instantly, all in the browser.
🧠 Powerful models - Select between Claude 4.5 Sonnet/Haiku, GPT-5 Codex, Gemini 2.5 Pro, and GLM 4.6.
💅 Production-ready results - Stunning UI and clean code, no manual edits needed.
🌐 100% in-browser - Go from prompt to deployment with no installs or configs.
💸 Up to 40% cheaper - Gelt charges by the message, not tokens.
✨ Higher output quality - Fewer model errors, smoother UX, and better results.
🧩 Maximum Accuracy on Every Turn - We never cache prompts, unlike every other major AI coding tool. This leads to a significant increase in and reliable results, especially for complex tasks.
We’ve been working hard to make AI development truly amazing - not just another vibe coding tool.
Can’t wait to see what you all build with it and hear your thoughts! 🚀

@etai_g Do you plan to include backend/DB capabilities?
@fabrizio1979 Hey Fabrizio, thanks for your support on our initial launch. Yes, if you check the site, the Supabase integration is upcoming. However, you can already try your own backend/DB by just prompting the agent. It should be able to handle it, as it can write full backends at a surprising success rate. The Supabase integration will make this as simple as one click, but I'm sure with some prompting you can get it done now too. Happy prompting :)
This is seriously impressive, Etai. Also love that you’re doing this at 16 that’s inspiring. The pay-per-message model and multi-model flexibility (Claude, GPT-5, Gemini, etc.) are smart touches too
@etai_g :)
Big congrats, Etai. An autonomous agent that reasons and self-corrects, plus pay-per-message and instant deploy, feels spot on. Love the 100% in-browser flow and no prompt caching for accuracy. How do you handle auth and long-running jobs in production?
