Open source coding agent that works in VS Code, JetBrains IDEs, the terminal and a kanban board, with any model you choose.
Cline reads a project's structure, works out how files relate to each other and makes coordinated changes across a codebase. It watches linter and compiler output while it works, catching missing imports, type mismatches and syntax errors before you see them.
One engine sits behind every client: the VS Code extension, the JetBrains plugin, the CLI, the kanban board and a Node SDK for building your own. In the editors, each change appears as a reviewable diff, and checkpoints let you undo the agent's work wholesale.
The pieces that decide how much rope the agent gets are yours to set.
- Plan and Act: explore and agree a strategy first, then switch to execution, approving each edit or letting it run unattended.
- Bash commands: runs commands and reads output live, staying with dev servers to react to crashes and test failures.
- Rules and skills: clinerules files carry coding standards and conventions, picked up by every client automatically.
- Kanban board: many agents in parallel, each card getting its own worktree, auto-commit and dependency chains.
- Model choice: Anthropic, OpenAI, Google, Bedrock, Vertex, OpenRouter, Groq, Ollama, LM Studio or any OpenAI-compatible endpoint.
- Plugins and MCP: register tools and lifecycle hooks through the SDK for logging, auditing or policy enforcement.
The CLI and kanban board install from npm and the extensions from their marketplaces. The JetBrains client is not open source, though the agent core it talks to is.
A desktop app for running several AI coding agents in parallel, each in its own Git worktree, for developers juggling multiple tasks.
Running more than one coding agent usually means juggling terminals and hoping none of them collide. Emdash gives every task its own Git worktree and branch, so several fixes or features can be explored at once and the diffs reviewed before anything is merged.
It is a desktop application that works against local projects and against remote machines over SSH and SFTP, with agent, key and password authentication and credentials held in the operating system keychain. Provider command-line tools already installed on the machine are detected automatically.
The workflow around the agents lives in the same window.
- Agent support: Claude Code, Codex, Cursor, OpenCode, Amp, Devin, Qwen Code, Droid and GitHub Copilot among others.
- Issue import: tickets from Linear, GitHub, Jira, GitLab, Asana, Featurebase, Monday.com, Forgejo or Plain go straight into an agent.
- Review and merge: diffs, pull request creation, CI checks and merges all happen in one place.
- Lifecycle hooks: marker-tagged entries in an agent's own config track status, notifications and resumable sessions, and stay inert outside Emdash.
- Local-first state: application state sits in a local SQLite database, and no code or chat reaches Emdash servers.
Apache-2.0 licensed builds cover macOS through Homebrew or a disk image, Windows as an installer or portable binary, and Linux as AppImage, DEB or RPM on x64 and ARM64. Telemetry is optional and switches off in settings or through an environment variable. The agent tools themselves still send prompts and context to their own providers, so their data handling is what applies to your code.
