+## Community & ecosystem tools
+
+Open-source tools built by the community around OKF:
+
+**Editors**
+- [OWOX Model Canvas](https://github.com/OWOX/owox-model-canvas) — visual canvas / ERD editor; imports & exports OKF v0.1 and opens the GA4, Stack Overflow and Bitcoin samples. Apache-2.0, free live demo.
+- [OnyxWriter](https://github.com/activetwist/OnyxWriter) — local-first desktop editor (Tauri) for OKF bundles: visual and raw editing, encrypted bundles, and MCP/CLI support.
+
+**Agent skills & toolkits**
+- [okf-knowledge](https://github.com/sniperunder123/okf-knowledge) — a portable `/okf` Claude Code skill to create, read, maintain and visualize bundles.
+- [okf-skills](https://github.com/scaccogatto/okf-skills) — a Claude Code toolkit to author, maintain, validate and visualize OKF bundles.
+- [okf-frontmatter](https://github.com/longsizhuo/okf-frontmatter) — a pure-Python agent skill that keeps repo docs under OKF with fast doc/schema lookup.
+
+**Validation & linting**
+- [okf-conformance](https://github.com/Sudhakaran88/okf-conformance) — a conformance criteria document plus an executable validator for OKF bundles.
+- [okf-lint](https://github.com/thisismydesign/okf-lint) — a linter for OKF bundles that catches conformance violations.
+
+**CLI**
+- [openknowledge](https://github.com/openknowledge-sh/openknowledge) — a Go CLI to create, inspect and publish OKF bundles (implements v0.1).
+
+**Generation & publishing**
+- [kiso](https://github.com/oak-invest/kiso) — a publishing engine that turns OKF bundles into static sites (with llms.txt and sitemap).
+- [KnowHub](https://github.com/smgam29/knowhub) — a model-agnostic pipeline that turns implementation documents (guides, PDFs, decks) into OKF bundles via cross-model extraction.
+- [OKFy](https://github.com/0dust/OKFy) — converts docs sites and local Markdown folders into OKF bundles, with validation, inspection, and an MCP server for agents.
