HumanLayer (including CodeLayer) is an open-source IDE and coding-agent platform aimed at enabling coding agents to solve hard problems in complex codebases. The project emphasizes context engineering and keyboard-first workflows, and provides tooling to run parallel Claude Code sessions, remote workers, and team-focused features.
Key features
- Agent workflows: orchestrate and run parallel Claude Code sessions, support worktrees and remote workers.
- Context engineering: promotes Advanced Context Engineering practices and the “12 Factor Agents” principles to improve agent reliability.
- Team and product features: team-oriented deployment options, integrations and premium services for organizations.
- Docs and examples: comprehensive docs, demos and example repositories to accelerate adoption.
Use cases
- Team-level AI-assisted development to improve debugging, code navigation and automated fixes in large codebases.
- Developer tools requiring parallel sessions, historical traces and remote execution.
- Research on context engineering and reproducible agent workflows.
Technical details
- Implementation: primarily TypeScript and Go, with front-end and back-end components.
- Deployment: supports local, cloud and managed deployments; repo contains contribution and development guides.
- License: Apache-2, actively developed with frequent updates and releases.
