Mainframe-Archive/switchboard

Switchboard is an Erlang-based email management platform that acts as a JMAP-to-IMAP proxy, enabling the monitoring and processing of emails across multiple accounts. It provides a WebSocket-based API for client interactions, including mailbox watching and message retrieval, while handling IMAP connections and OAuth authentication. The system is supported by comprehensive documentation, a Jekyll-based site, and automated provisioning infrastructure.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 1 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 37b66a5326 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
