Inkstone is a self-hosted Markdown notebook that runs on Cloudflare Workers. It combines a browser-based Markdown editor, folders, tags, backlinks, D1 full-text search, optional Workers AI semantic search, public shares, readable exports, WebDAV/S3 backups, PWA offline behavior, and scoped MCP access.

It is self-hosted by deploying into your own Cloudflare account rather than by running a single Docker Compose stack.
