JetBot

Browser-based AI Coding Assistant — Zero Install. Zero Deploy. Zero Config.

中文文档

JetBot is a fully browser-based AI coding assistant. No backend server, no deployment pipeline, no installation required — just open the page and start working. All code executes client-side via JavaScript; LLM calls go directly from the browser's fetch() to your chosen API provider.

Features

Agentic Loop

An autonomous tool-calling loop where the LLM selects tools, executes actions, and analyzes results until the task is complete. Supports up to 100 iterations with circuit breaker protection (3 consecutive failures) and automatic duplicate-error detection.
