State of OKF 2026
The definitive ecosystem report on the Open Knowledge Format — data-driven analysis of 829 bundles, 7068 stars, and the fastest-growing knowledge format for AI agents.
1. Executive Summary
The Open Knowledge Format (OKF), launched by Google Cloud Platform in June 2026, has seen explosive growth in its first weeks. BundleDex, the definitive OKF bundle directory, now indexes 829 bundles from 645 authors — accumulating 7068 total GitHub stars across 1122 unique tags. This report analyzes the ecosystem's composition, growth trajectory, and key trends.
2. Ecosystem Overview
The OKF ecosystem is diverse, spanning AI agent skills, documentation tooling, domain-specific knowledge bases, and reference datasets. The format's simplicity — plain markdown files with YAML frontmatter — has lowered the barrier to entry, enabling contributions from individual developers, open-source projects, and organizations alike.
The average bundle has approximately 9 stars, though the distribution is heavily skewed by a few top-performers. The median bundle is newer and smaller, reflecting rapid ecosystem expansion.
3. Category Breakdown
Bundles span 1 categories. Here is the distribution:
Example Datasets and Uncategorized make up the largest cohorts, reflecting early experimentation. Content & Publishing (50 bundles) shows strong use of OKF for documentation-as-code, while Tooling & SDKs (36 bundles) demonstrates growing infrastructure around the format.
4. Top 10 Most-Starred Bundles
The following bundles have the highest GitHub star counts in the OKF ecosystem:
Markdown memory system for you and your AI agent
Git-native persistent memory for AI coding agents. Implements Google OKF v0.2 with sub-300µs in-memory BM25 search, embedded MCP server, and progressive disclosure. Slashes token bloat by 80% with zero external databases or dependencies. Built in pure Go.
Distill videos, PDFs, transcripts, and notes into source-backed teacher Agent Skills.
AI-native engineering environment management that makes your codebase agent-ready.
Open-source memory and context for user-aware agents: scoped memory, provenance, retrieval quality, correction, boundaries, evals, and MCP/HTTP access.
Persistent memory plugin for OpenCode. Obsidian-style knowledge base that survives across sessions
Your architecture as OKF Markdown in Git, and one C4 map you can walk. Scanned from source, curated by you and your agents.
An Open Knowledge Format (OKF) bundle of Cole Medin's best AI-coding videos — mount it in any AI second brain and search it deeply. Transcript-verified.
An OKF (Open Knowledge Format) knowledge base + Karpathy-style LLM wiki synthesized from Cole Medin's entire long-form YouTube catalog. Drop it next to any project for agent-ready, cited reference. No database, no embeddings.
Persistent memory plugin for Codex. Obsidian-style knowledge base that survives across sessions
5. Fastest-Growing Bundles
These bundles gained the most stars between 2026-07-05 and 2026-10-04 (absolute growth):
1274 → 1745 stars (37% growth) — Markdown memory system for you and your AI agent
267 → 449 stars (68% growth) — Distill videos, PDFs, transcripts, and notes into source-backed teacher Agent Skills.
60 → 134 stars (123% growth) — An Open Knowledge Format (OKF) bundle of Cole Medin's best AI-coding videos — mount it in any AI second brain and search it deeply. Transcript-verified.
7 → 62 stars (786% growth) — CLI tool for managing Open Knowledge Format (OKF) bundles.
11 → 47 stars (327% growth) — Kiso is a publishing engine that turns Open Knowledge Format (OKF) bundles into static websites for humans and AI agents.
Lineage Skill leads absolute growth with +471 stars, driven by its adoption as a Claude Code skill template. Data Olympus showed the highest percentage growth at 1500%, reflecting the growing interest in OKF-curated knowledge datasets.
6. Growth Trend
The OKF ecosystem has grown rapidly since launch. BundleDex initially tracked ~250 bundles. Today, we index 829 bundles — a 232% increase in just weeks. The star count grew from 2640 to 7,068 in 91 days alone.
We expect continued acceleration as more developers discover OKF, more tools add native support, and the BundleDex discovery ecosystem (MCP server, JSON API, topic pages) makes finding the right bundle frictionless.
7. OKF Conformance
Of the 829 bundles indexed, 312 (38%) pass formal OKF conformance validation. This means they follow the exact directory structure, frontmatter schema, and cross-linking conventions defined in the OKF specification.
Non-conformant bundles may use OKF-like structures (markdown files with YAML frontmatter) but haven't been validated against the spec. We expect conformance rates to rise as validation tools like OKF Conformance and OKF Go Parser become more widely used.
8. Outlook & What's Next
The OKF ecosystem is still in its infancy. With 829 bundles and growing, we anticipate several trends:
- Enterprise adoption: As OKF matures, expect enterprises to adopt it for internal knowledge management, replacing proprietary wiki solutions.
- Specialized SDKs: More language-specific SDKs for loading and querying OKF bundles at runtime.
- Cross-agent portability: OKF bundles that work across Claude Code, Cursor, OpenCode, and custom agent frameworks interchangeably.
- Automated validation in CI: GitHub Actions and GitLab CI pipelines that validate OKF structure on every pull request.
- AI-generated bundles: Tools that automatically convert existing documentation, wikis, and codebases into OKF format.
9. Frequently Asked Questions
How is this data collected?
BundleDex scans GitHub, GitLab, and other public repositories daily, indexing any repository tagged with 'okf' or meeting OKF structural criteria. Stars and metadata are refreshed on each scan.
What qualifies as an OKF bundle?
A repository that contains an index.md file with YAML frontmatter including okf_version, a concepts directory, and follows the OKF directory structure. Some bundles are indexed before full conformance is verified.
How often is this report updated?
This report is refreshed whenever the BundleDex index is regenerated. Check the trending page for real-time ecosystem metrics.
