Emdash is a provider-agnostic desktop app that lets you run multiple coding agents in parallel, each isolated in its own git worktree, either locally or over SSH on a remote machine. We call it an Agentic Development Environment (ADE).

Emdash supports 27 CLI agents, including Claude Code, Codex, OpenCode, Gemini and Amp. Users can directly pass Linear, GitHub, Jira, or Asana tickets to an agent, review diffs, test changes, create PRs, see CI/CD checks, and merge.

Develop on remote servers via SSH

Connect to remote machines via SSH/SFTP to work with remote codebases. Emdash supports SSH agent and key authentication, with secure credential storage in your OS keychain. Run agents on remote projects using the same parallel workflow as local development. Learn more

FAQ

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 Telemetry.

App data 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
Privacy Note: While Emdash itself stores data locally, when you use any coding agent (Claude Code, Codex, Qwen, etc.), your code and prompts are sent to that provider's cloud API servers for processing. Each provider has their own data handling and retention policies.

You can reset the local DB by deleting
