Amazon has released Kiro Crew as an open-source system for coordinating multiple Kiro coding agents across sessions, tools, and tasks. Developers can assign asynchronous work such as incident investigations, ticket triage, migrations, and pull-request monitoring without continuous supervision.
Kiro Crew provides shared memory, reusable skills, scheduled jobs, concurrent agents, and dedicated Apps. Agents can preserve project context, continue working while developers are away, delegate to subagents, and connect to external services through MCP and webhooks.
The system was developed internally at Amazon under the name MeshClaw and was reportedly adopted by more than 39000 developers. It can now run locally or on infrastructure controlled by developers. Its creators said they wanted a way to start work, leave it running, review the results later, and handle multiple tasks without supervising individual prompts.
Kiro Crew coordinates agents through the Agent Client Protocol (ACP). Its Activity view provides live information about agent plans, tool calls, approval gates, and results.
Security features include an OS-level sandbox, commands denied by default, suspicious-pattern blocking, input validation, sensitive-path blocking, credential redaction, and signed audit logs covering every action.
The project can be adapted through MCP, Apps, orchestration, and reusable skills. It can also use skills created for other open, standards-based agent platforms without modification.
Early community feedback has been largely favorable, particularly regarding the reported internal adoption of 39,000 developers and 500 contributors over six months. Users have described applications including CI/CD migrations, Dependabot triage, scheduled tasks, and other long-running jobs.
Some developers have warned that Kiro Crew may consume tokens substantially faster than Kiro CLI. Others highlighted the value of background subagents for parallel work and the ability to retain context between sessions.
Kiro Crew runs on Kiro CLI and supports existing .kiro configurations, including steering files, skills, and custom agents. It is licensed under Apache 2.0 and supports macOS, Linux, and Windows, with integrations for Slack, Telegram, and WeCom.
Kiro and AWS engineers will initially maintain the project. The announcement also invites community involvement in development and roadmap planning, with external maintainers able to join as contributors as the project grows.
