What is it?

Helmor is a desktop workbench for running several coding agents at once. Each task gets its own git worktree and branch, so agents working on different tasks do not interfere with each other. The conversation, diffs, Monaco editor and terminals sit side by side in one window, and the workspace data is stored locally under ~/helmor/.

It works with existing agent tools such as Claude Code, Codex, Cursor, OpenCode and Kimi Code, using the user's own logins, API keys and custom providers. From the same window, users can create, merge and fix pull or merge requests on GitHub and GitLab, resolve conflicts and manage stacked PRs.

Helmor also ships a `helmor` CLI and an MCP server, so a terminal or another agent can create workspaces, send prompts and trigger actions. A mobile companion mode is marked as experimental.
