AI-First In-Browser IDE for React Development
Localhost service isolation and orchestration for git worktrees
JSX Tool is a browser extension that hooks into your React project, so you can easily locate any React component and file with just a click. This gives developers the ability to articulate visual requests to LLMs that without JSX Tool, are either vague or cumbersome to communicate in English and code snippets. On top of that JSX Tool is a full featured IDE tailored specifically for React Development, so users never have to leave the context of their browser when developing React code.
A Coast (containerized host) is a local development runtime. Coasts let you run multiple isolated environments for the same project on one machine. As AI coding agents increasingly work in parallel across git worktrees, developers hit painful conflicts — clashing ports, duplicated databases, and fragile per-branch setup. Coasts solve this by giving each worktree its own fully isolated runtime, so multiple agents can build and test side by side without stepping on each other.
JSX Tool pivoted from a React-specific browser IDE to containerized local development environments for managing multiple git worktrees - completely different product solving an entirely different problem.
