OKF Index

OKF Index is a free search tool that helps developers and AI agents discover Open Knowledge Format bundles: markdown trees whose root index.md declares an okf_version. It sweeps public GitHub repositories and accepts submissions from live domains via the IndexNow protocol. Users can search by topic, subject, or host, compare bundles in tabs, and copy the raw index.md URL for an agent to follow. Filters allow narrowing by concept count, declared root type, OKF version, repository language, or license. The service is free with no account required, aimed at developers and agent builders wanting structured, machine-readable knowledge sources.
