Review first — review before installing

Open the source and read safety notes before installing.

Safety notes

  • CodeLayer orchestrates AI coding agents that edit files and run commands in your repositories, so it inherits the execution risks of the underlying Claude Code agent.
  • MultiClaude runs multiple Claude Code sessions in parallel across git worktrees; review changes per worktree before merging to avoid conflicting or unreviewed edits.
  • Remote cloud workers can run agent sessions on external infrastructure; understand where code executes before enabling them.
  • Scaling agent workflows to a whole team increases the blast radius of automated edits, so keep human review and branch protections in place.

Privacy notes

  • Because it builds on Claude Code, repository code and context are sent to Anthropic's API to power the agent.
  • Remote cloud workers process your code and context on external infrastructure; review the provider's terms before sending private code.
  • Any API keys or credentials used by Claude Code and CodeLayer should be stored as secrets, not committed to source control.
  • Team and context-engineering features can share prompts, context, and workflow data across collaborators, so avoid placing secrets in shared context.

Prerequisites

  • Claude Code, since CodeLayer is built on top of it and orchestrates Claude Code sessions.
  • An Anthropic account or API access for the underlying Claude Code agent.
  • A recent CodeLayer build from the project's GitHub releases or the waitlist for early access.
  • Git, since parallel-session workflows rely on worktrees.

## Overview

HumanLayer is the open-source project behind CodeLayer, an IDE for orchestrating
AI coding agents. It is built on Claude Code and aims to help builders and teams
get AI coding agents to solve hard problems in large, complex codebases — from a
single laptop up to an entire team.

The project is released under Apache-2.0. CodeLayer focuses on keyboard-first
workflows, context engineering for scaling AI-first development across a team,
and running Claude Code sessions in parallel.

## Features

- Keyboard-first workflows designed for speed and control.
- Context engineering to scale AI-first development across a team.
- MultiClaude: run multiple Claude Code sessions in parallel, including across
  git worktrees and remote cloud workers.
- Built on Claude Code, so it reuses the underlying agent and its tooling.
- Open-source under Apache-2.0, with team and consulting services available.

## Use Cases

- Drive several Claude Code sessions at once across isolated worktrees.
- Standardize AI-assisted development context and workflows across a team.
- Tackle large-codebase tasks that need orchestration beyond a single session.
- Offload agent sessions to remote cloud workers when local resources are tight.
