AI agents build, run, & deploy your next full-stack app
With Gelt, you can prompt, run, and deploy full-stack web apps in minutes - no setup or coding needed. Fully Agent-powered, production-ready, and up to 40% cheaper than competitors. Pay per message, integrate Stripe and more in one click, and deploy instantly.
👋 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! 🚀
