Overview

Helmor is an open-source, local-first IDE for coding agent orchestration. It is designed as a workbench for multi-agent software development, with a focus on managing the workflow around code rather than only generating code.

The product positions itself around the full loop of planning, running, reviewing, testing, and merging. Its homepage highlights support for Claude Code and Codex side-by-side across worktrees on the user’s machine, which suggests a workflow built for coordinating multiple agents while keeping source code local.

Core features

Local orchestration workspace

Helmor is built as a local workbench for multi-agent software development, with the app centered on coordinating agent work rather than replacing an editor.

Side-by-side agent support

The product supports running Claude Code and Codex side-by-side, letting users compare outputs or divide work between agents in the same project flow.

Worktree-based execution

Helmor works across worktrees on your machine, which fits agent workflows that need isolated branches or parallel changes.

End-to-end coding loop

The homepage highlights planning, running, reviewing, testing, and merging as the surrounding loop the product is meant to manage.

Open-source distribution

The site calls Helmor open source and shows an Apache-2.0 license badge on the homepage.

Practical use cases

Local agent orchestration
Use Helmor when you want to coordinate agent work locally and keep the source tree on your own machine while you move through implementation and review steps.
Parallel model workflows
Use it to run Claude Code and Codex on the same project and compare their output or split tasks across worktrees.
Worktree-based experimentation
Use it for work that benefits from isolated branches, such as trying multiple approaches before choosing one to merge.
Review and merge workflows
Use it as a hub for the surrounding development loop when you need to review, test, and merge changes after an agent has produced code.
