The best way to get AI coding agents to solve hard problems in complex codebases.
HumanLayer is an open-source project centered on CodeLayer, a keyboard-first IDE built on top of Claude Code that lets developers orchestrate multiple AI coding agents simultaneously. Its headline feature, called MULTICLAUDE, runs parallel Claude Code sessions using Git worktrees or remote cloud workers, allowing teams to tackle several workstreams at once rather than waiting on a single agent. The project also includes a legacy HumanLayer SDK focused on human-in-the-loop approval workflows for agentic tasks. Context engineering is a core design philosophy here, drawing on the team's prior work including the "12 Factor Agents" framework, which applies principles similar to the original 12-Factor App methodology to LLM-based systems. CodeLayer targets individual developers and engineering teams who want structured, repeatable workflows around Claude Code rather than ad-hoc prompting, and a team-tier offering pairs organizations with HumanLayer engineers for custom integrations. The project is licensed under Apache 2 and is currently in waitlist access.
