Many conversations at once
Each conversation is its own agent with its own model and working directory. Run several side by side, archive them, search them. Conversations live in one SQLite database. More →
Web-based, mobile-friendly, multi-conversation, multi-modal, multi-model. One binary. Open source and self-modifying.

Shelley is a mobile-friendly, web-based, multi-conversation, multi-modal, multi-model, single-user coding agent built for but not exclusive to exe.dev. It does not come with authorization or sandboxing: bring your own.
A shell, precise patch edits, a headless browser for navigating and screenshotting, subagents, one-shot calls to other models, and inline HTML for charts and diagrams. More →
Edits render as real diffs, and a side-by-side diff viewer shows everything that changed. Browse the git graph, comment on lines, and ask for a commit tour: an annotated walkthrough of a change, saved as a git note. More →
Anthropic, OpenAI, Gemini, and Fireworks keys from the environment, plus custom OpenAI-, Anthropic-, or Gemini-compatible endpoints. Switch models between turns. More →
Built-in skills plus your own (shelley skill new). Connect remote MCP servers ( shelley mcp add). Drop executable scripts in ~/.config/shelley/hooks to rewrite prompts, add slash commands, or react to turns (hooks).
Talk instead of typing, or record your voice and screen while you point at the problem; the agent gets the transcript, the video, and timestamps to match them up. Paste screenshots straight into the chat. It’s a web page; your phone works too.
Go backend, SQLite storage, the Vue UI embedded. Download it, run it, open a tab. New releases ship on every push to main that passes tests. Install →
Shelley grew out of Sketch, and unsurprisingly much of it is written by Shelley, Sketch, Claude Code, and Codex.
