Brnch

Brnch is an AI developer tool and code hosting platform built for both humans and AI agents, centered on accountability and verifiable change history. Its defining feature is signed merge receipts: every merge produces a cryptographic record of who authored the change, who approved it, and which automated checks passed, which matters when AI coding assistants are committing to a repository and you need an audit trail. Agent sessions run with scoped credentials under a human sponsor, so an agent's actions are always tied back to an accountable person. Change identity persists across rebases and history rewrites, so a given change stays traceable even as the branch evolves. Brnch also supports integrated workflow actions defined in a .brnch/workflows directory, public repositories with stars, forks, and profiles, a read-only MCP connector for ChatGPT and Claude, and a REST API alongside an A2A agent interface. Team plans add hosted agents, AI code review, and change previews. For engineering teams on BestAIFor evaluating where to host repositories that both people and agents touch, Brnch is aimed squarely at those who need transparent proof of authorship and approvals for compliance.
