HumanLayer

HumanLayer is a multiplayer coding agent IDE that coordinates team collaboration by bringing agent sessions, plan artifacts, and code diffs into one unified workspace.

HumanLayer provides a collaborative workspace for teams to orchestrate AI coding agents and manage development workflows. It synchronizes agent sessions, plan artifacts, and code diffs, allowing developers to review design docs and implementation steps alongside agents. The platform supports integration with various AI models like Claude Code, Codex, and Copilot through bring-your-own-key (BYOK) setups, enabling users to run agents on local workstations or in the cloud. It features a structured six-phase workflow that facilitates comment-driven refinement, ensuring human oversight during research, planning, and implementation. By connecting design documentation directly to the codebase, the environment prevents disconnected workflows and ensures that human feedback feeds back into agent execution. It is designed for software teams that need to maintain context and control over large codebases while utilizing autonomous coding agents.
