Show HN: Friday – Self-hosted persistent memory for AI coding agents (MCP)

Every developer deserves a F.R.I.D.A.Y. The open-source, self-hosted persistent cognitive memory layer for AI coding agents. Cursor forgets. Claude forgets. Copilot forgets. Friday doesn't.

You're deep in a session with Cursor. You've explained your entire auth architecture. Your JWT strategy. Your database schema. Your preferred patterns.

You: "Add a refresh token endpoint using our JWT pattern." Cursor: "Sure! What JWT library are you using? And how is your auth structured?" You: 😤 (again. for the 47th time this week.) Every AI coding assistant suffers from the same critical design flaw: no persistent memory.

Each session starts at zero. Your AI gives you generic advice instead of deeply personalized, project-specific insight. You're repeating yourself constantly.

The result? You're spending up to 40% of your time just rebuilding context — instead of building product.
