Kiwifs

KiwiFS is a markdown filesystem for AI agents and teams, shipped as a single Go binary. It turns markdown files on disk into a searchable, queryable, versioned store that can be reached over REST, MCP, NFS, S3, WebDAV and FUSE. Every page is a plain markdown file with YAML frontmatter, and every write becomes a git commit, which gives history, blame, diff and rollback. Search combines BM25 full text search on SQLite FTS5 with optional vector embeddings. A SQL like query language called DQL works over frontmatter metadata. A built in web interface offers wiki links, a knowledge graph, Mermaid diagrams, editing, saved views, a canvas and a whiteboard. Optional features include draft spaces that stage agent edits in git backed branches before merge, task claims that stop two agents editing the same path at once, an audit log, webhooks and schema enforcement. Agents can use ordinary commands such as cat and grep, or connect Claude, Cursor and other AI tools through MCP. It is aimed at developers who need shared, structured memory or knowledge storage for agents and human teammates, and it runs with no configuration, with no Node or Docker requirement. KiwiFS is released under the Business Source License 1.1, which the vendor calls Fair Source, allowing self hosting and embedding, with each release converting to Apache 2.0 after four years. No pricing is published on the documentation site.
