campfirein/cipher: Cross-Tool Memory Layer for Coding Agents — Cursor, Claude Code, Windsurf, Gemini CLI, Kiro

GitHub·medium signal

Cipher (3,609 stars) is an open-source memory layer built specifically for coding agents, capturing project context, architectural decisions, and recurring patterns across sessions. Notable for being explicitly compatible with the broadest agent toolset documented: Cursor, Codex, Claude Code, Windsurf, Cline, Claude Desktop, Gemini CLI, and AWS Kiro. Functions as infrastructure-layer memory that survives IDE switches and team handoffs.
