Run multiple coding agents in parallel—provider-agnostic, worktree-isolated, and local-first.

Emdash lets you develop and test multiple features with multiple agents in parallel. It’s provider-agnostic (we support 10+ CLIs, such as Claude Code and Codex) and runs each agent in its own Git worktree to keep changes clean; when the environment matters, you can run a PR in its own Docker container. Hand off Linear, GitHub, or Jira tickets to an agent, review diffs side-by-side, and keep everything local.

FAQ

What telemetry do you collect and can I disable it?

We send anonymous, allow‑listed events (app start/close, feature usage names, app/platform versions) to PostHog.
We do not send code, file paths, repo names, prompts, or PII.

Disable telemetry:

• In the app: Settings → General → Privacy & Telemetry (toggle off)
• Or via env var before launch:

TELEMETRY_ENABLED=false

Full details: see docs/telemetry.md.

Where is my data stored?

Everything is local‑first. We store app state in a local SQLite database:

macOS:  ~/Library/Application Support/emdash/emdash.db
Windows: %APPDATA%/emdash/emdash.db
Linux:  ~/.config/emdash/emdash.db

You can reset by deleting the DB (quit the app first). The file is recreated on next launch.

Do I need GitHub CLI?

Only if you want GitHub features (open PRs from Emdash, fetch repo info, GitHub Issues integration).
Install & sign in:

gh auth login

If you don’t use GitHub features, you can skip installing gh.

How do I add a new provider?

Emdash is provider‑agnostic and built to add CLIs quickly.

• Open a PR following the Contributing Guide (CONTRIBUTING.md).
• Include: provider name, how it’s invoked (CLI command), auth notes, and minimal setup steps.
• We’ll add it to the Integrations matrix and wire up provider selection in the UI.

If you’re unsure where to start, open an issue with the CLI’s link and typical commands.

I hit a native‑module crash (sqlite3 / node‑pty / keytar). What’s the fast fix?

This usually happens after switching Node/Electron versions.

1. Rebuild native modules:

npm run rebuild

2. If that fails, clean and reinstall:

npm run reset

(Resets node_modules, reinstalls, and re‑builds Electron native deps.)

What permissions does Emdash need?

• Filesystem/Git: to read/write your repo and create Git worktrees for isolation.
• Network: only for provider CLIs you choose to use (e.g., Codex, Claude) and optional GitHub actions.
• Local DB: to store your app state in SQLite on your machine.

Emdash itself does not send your code or chats to our servers. Third‑party CLIs may transmit data per their policies.
