Every AI conversation starts from zero. Your projects, decisions, and preferences disappear as soon as you close the chat. Second Brain fixes that. It is a self-hosted memory layer that works with Claude, ChatGPT, Cursor, and any MCP client. You can store context once and recall it by meaning instead of keywords. It includes duplicate detection, semantic search, and a web UI. Built on Cloudflare, it offers a free tier and your data remains yours. MIT licensed.

Workers runs at the edge with no cold starts, includes D1 (SQLite) and Vectorize (vector DB) natively, and the free tier is genuinely generous. I didn’t want users to need a paid plan just to run their own memory layer. No other platform bundles compute + vector search + relational DB for free.

Cloudflare Workers + D1 + Vectorize is the only stack where I can run semantic vector search, a relational DB, and an API, all on a free tier, globally distributed, with zero cold starts. Nothing else comes close for a self-hosted tool that needs to be cheap to run forever.

VS CodeMicrosoft Visual Studio Code lets you build and debug apps

I used VS Code as my main IDE. Cursor is built on top of VS Code, so the two work together. I relied on Cursor for AI-assisted coding, but the main editor, keybindings, extensions, and configuration are all from VS Code. I tried Antigravity, but it felt too early; the developer experience wasn’t there yet. I stick with VS Code because its ecosystem is unmatched: the extension library, terminal integration, and the fact that every tool I use has a VS Code integration first.
