Fletch
The IDE for agentic engineering·fletch.sh
Fletch is a macOS app that runs multiple AI coding agents (Claude Code, Codex, Cursor, OpenCode, Pi, and others) in parallel, each in its own isolated git-clone sandbox so they never collide. It chains agents into deterministic specialist workflows — plan, build, review, test — with a gate at every step, and lets the user review live diffs and commit, push, or open a PR from one window. It orchestrates existing tools like Greptile, CI, and test suites rather than replacing them, and is local-first, meaning code stays in the user's git and Fletch's servers never see the source.
What it's for
Features 14
- Autopilot: fixes failing checks on an enrolled PR, reconciles diverged branches, works review comments
- Codegraph indexing so agents prefer the index over grep
- Deterministic specialist workflows: architect, coder, reviewer, tester with gates at each step
- Docker container sandboxing option
- Each agent works in its own full clone under a hard sandbox (real isolation)
- Forking a workspace to branch an agent's code and conversation
- GitHub connection for PRs and CI status
- Keyboard shortcuts, slash commands, and terminal view
- Live diff review before merging
- MCP (Skills and Tools) support to extend custom agents
- One-click commit, push, open PR, and merge
- Orchestrates existing tools you already use (Greptile, your CI, your test suite)
- Runs multiple AI coding agents in parallel
- Supports Claude Code, Codex, Cursor, OpenCode, Pi and other coding agent CLIs
Pricing
Fletch is free; agent CLIs (Claude Code, Codex, Cursor, etc.) are separate subscriptions the user already pays for.
Fletch itself is free; users bring their own agent subscriptions (Claude Code, Codex, Cursor, etc.). No account required.
