RFC123
The agent-native & open-source platform for RFCs .
Write RFCs like a cracked engineer
Just Markdown. The format you already write in, with no proprietary editor or special syntax.
Git for documents. Every draft, every open review, every merged decision lives in Git, via GitHub. Versioning is foundational here.
Collaborate with maximum synergy
The best interface to comment on a document. Threads attach to any line or selection, in both the rendered view and the raw Markdown editor.
A queue of your own. Review requests pinned at the top, including ones assigned to your GitHub teams. Filter by author or repo.
Never miss a thing
Your review queue, delivered to Slack. A single DM at the hour and timezone you choose.
No noise. Empty days skipped. Weekends off by default.
I think RFC123 might be the second-best addition to my professional life! I love it.
Bring your agent to the table
Connect Claude, ChatGPT, or any agent with our MCP server. One click to authorize. Your agent lists, reads, and discusses every RFC alongside you. It can draft for you too, but the MCP server won’t let it post comments or replies on your behalf, so no AI slop ever lands on your team.
Skills for digging deep. With RFC123 skills, your assistant becomes an expert in comparing proposals against codebases, synthesizing discussions, extracting action items, or suggesting reviewers.
