Local workbench for coding agents and git workspaces

Helmor runs coding agents in isolated git workspaces so you can prompt one agent, review its diff, and ship from the same place. It combines a desktop app, a CLI, and an MCP server, so you can use it from the app or drive it from the terminal and other tools.

Who it's for

Builders who want their agents to work in parallel inside local git worktrees.

What it delivers

You can manage agent-led tasks, review changes, and create PRs without juggling separate tools.

What it does

Isolated workspaces

Creates one git worktree and branch per task so agents do not overwrite each other.

Bring your own agents

Works with Claude Code, Codex, Cursor, OpenCode, and Kimi Code using your own logins, API keys, and providers.

Side-by-side review

Shows diffs, a Monaco editor, and terminals next to the agent conversation.

One-button shipping

Creates PRs or MRs, merges changes, fixes CI, resolves conflicts, and handles stacked PRs for GitHub and GitLab.

Terminal mode

Runs prompts in the agent’s native TUI or resumes a GUI chat from the terminal.

Quick panel

Opens a floating window so you can start a workspace and chat from anywhere.

Scriptable CLI and MCP server

Lets your terminal or another agent drive Helmor through `helmor` commands or MCP over stdio.

Skills support

Installs skills from onboarding or Settings → Helmor Components and lets you browse them with `/` in the composer.

How to get it

  1. 1Install from Settings → Experimental → Command Line Tool. Works against the same local…
    helmor repo add /path/to/repo
    helmor workspace new --repo myapp
    helmor workspace list
    helmor send --workspace myapp/feature-x "Add a test for the parser edge case."
    helmor workspace status myapp/feature-x
    helmor workspace run-action myapp/feature-x   # create PR, merge, fix CI, …
    helmor mcp                                    # MCP server over stdio
  2. 2Example — an agent ships a fix
    helmor workspace new --repo myapp --name fix-auth
    helmor send --workspace myapp/fix-auth "Add tests for the token refresh path."
    helmor workspace status myapp/fix-auth
    helmor workspace run-action myapp/fix-auth

Helmor

The local-first workbench for orchestrating coding agents.

AI made coding faster.

Helmor is about finishing the rest of the loop — orchestrating, reviewing, testing, merging, and actually shipping software.

Helmor runs many coding agents in parallel, each in its own isolated git workspace — conversation, diffs, editor, terminals, and one-click PR actions in one window. Everything lives locally under ~/helmor/.

Features

  • Isolated workspaces — one git worktree and branch per task; agents never step on each other.
  • Bring your own agents — Claude Code, Codex, Cursor, OpenCode, and Kimi Code; your logins, API keys, and custom providers.
  • Review without leaving — diffs, Monaco editor, and terminals beside the conversation.
  • Ship from one button — create PR/MR, merge, fix CI, resolve conflicts, stacked PRs; GitHub and GitLab.
  • Terminal Mode — run prompts in the agent's native TUI, or resume a GUI chat in the terminal.
  • Quick panel — ⇧⌥Space opens a floating window to start a workspace and chat from anywhere.
  • Scriptablehelmor CLI and MCP server; your terminal or another agent can drive Helmor.
  • Skills — install from onboarding or Settings → Helmor Components; browse with / in the composer.
  • Mobile companion (experimental) — Cloudflare tunnel to your desktop; start tasks from your phone's browser.

More on the way — Slack & GitHub context, plan mode, and agent-driven orchestration.

How it works

flowchart LR
  A[Add a repository] --> B[Create a workspace]
  B --> C[Prompt an agent]
  C --> D[Review and ship]
  D -.->|repeat in parallel| B
  1. Add a repository — link a local clone, or clone from a URL.
  2. Create a workspace — fresh git worktree and branch under ~/helmor/workspaces/.
  3. Prompt an agent — describe the task and move on while it runs.
  4. Review and ship — read the diff, run tests, create and merge the PR.

Get started

Download Helmor →

macOS (Apple Silicon & Intel) · Windows (x64)

Read the docs →

On first launch, connect GitHub or GitLab and sign in to your first agent. Agent CLIs are bundled — nothing else to install.

CLI

Install from Settings → Experimental → Command Line Tool. Works against the same local database as the app — even while it is running.

helmor repo add /path/to/repo
helmor workspace new --repo myapp
helmor workspace list
helmor send --workspace myapp/feature-x "Add a test for the parser edge case."
helmor workspace status myapp/feature-x
helmor workspace run-action myapp/feature-x   # create PR, merge, fix CI, …
helmor mcp                                    # MCP server over stdio

Workspaces use repo-name/directory-name shorthand. Every command supports --json. Run helmor --help for the full reference.

Example — an agent ships a fix:

helmor workspace new --repo myapp --name fix-auth
helmor send --workspace myapp/fix-auth "Add tests for the token refresh path."
helmor workspace status myapp/fix-auth
helmor workspace run-action myapp/fix-auth

Contributing

Architecture, commands, and test layout live in AGENTS.md. To get started locally: bun install && bun run dev.

Or —

Open Helmor, Import Helmor, Ask Helmor:

"How do I contribute to Helmor?"

That's the guide.

Community

  • Discord — questions, feedback, release chat
  • GitHub Issues — bugs and feature requests
  • Or use the feedback button at the bottom of Helmor's sidebar
