What is HumanLayer?

HumanLayer provides an open-source IDE and orchestration layer for AI coding agents, enabling developers to run Claude Code sessions and manage parallel agents across projects. It supports multiclaude workflows, worktrees, and remote cloud workers for distributed development and scalable AI-first development.

Built-in context engineering tools and 12-Factor Agents guidance help maintain reliable, reproducible LLM applications in large, complex codebases. Keyboard-first workflows and workflow templates streamline developer tasks, code navigation, and session replay for debugging and audit.

Integrations with GitHub and custom integrations enable team collaboration, CI-aligned workflows, and code review automation. Target users include individual developers, engineering teams, and platform engineers seeking scalable AI coding workflows, context management, and reproducible agent orchestration.
