Skill and adoption surfaces are [MIT](./LICENSE). Engine-linked runtime is BSL-1.1 source-available, not OSI Open Source before Change Date.\n\n**MIT:** the skill, Agent SDK and initializer, the CLI, both client SDKs, contracts, provider catalog, extension shell, and the thin cavemem clients. Free like mammoth on open plain.\n\n**BSL-1.1:** Engine, Proxy, Cache Engine, rewriter, Browse, MCP server, `shrink`, cavemem Go core, and shared Go platform. New Engine-linked runtime modules default to BSL-1.1. Read it, fork it, self-host it for your own first-party traffic free, production included. Each version converts to **Apache-2.0** on the earlier of `2030-06-21` or four years after it ships. Hosting it for third parties needs a commercial license.\n\n`engine/pixel` embeds [pxpipe](https://github.com/teamchong/pxpipe) (MIT) plus glyph atlases derived from Spleen 5×8 (BSD-2-Clause) and GNU Unifont (dual OFL-1.1 / GPLv2-with-font-exception); its `NOTICE` travels with that source.\n\n\"Caveman\" and the rock logo are trademarks of Julius Brussee. \"Powered by Caveman\" is fine when true.","github_created_at":"2026-04-04T10:03:00+00:00","created_at":"2026-07-07T17:30:34.309883+00:00","updated_at":"2026-09-20T04:32:00.170692+00:00","categories":[{"slug":"ai-agents","name":"AI Agents","url":"https://www.graphcanon.com/categories/ai-agents","markdown_url":"https://www.graphcanon.com/categories/ai-agents.md","api_url":"https://www.graphcanon.com/api/graphcanon/categories/ai-agents"},{"slug":"model-training","name":"Model Training","url":"https://www.graphcanon.com/categories/model-training","markdown_url":"https://www.graphcanon.com/categories/model-training.md","api_url":"https://www.graphcanon.com/api/graphcanon/categories/model-training"}],"tags":[{"slug":"ai","name":"ai"},{"slug":"anthropic","name":"anthropic"},{"slug":"caveman","name":"caveman"},{"slug":"claude","name":"claude"},{"slug":"claude-code","name":"claude-code"},{"slug":"llm","name":"llm"},{"slug":"meme","name":"meme"},{"slug":"prompt-engineering","name":"prompt-engineering"}],"trust":{"provenance":{"is_fork":false,"github_id":1201173969,"owner_type":"User","methodology":"github_public_v1","parent_repo":null,"near_duplicate_slugs":[]},"computed_at":"2026-09-18T08:36:04.165Z","maintenance":{"label":"Very active","score":96,"methodology":"github_public_v1","releases_90d":20,"days_since_push":0,"last_release_at":"2026-09-15T04:01:16Z","stars_delta_30d":7978,"open_issues_delta_30d":-358},"security_summary":{"status":"ok","scanner":"osv@v1","low_count":0,"high_count":0,"last_scan_at":"2026-09-18T08:36:05.847Z","medium_count":0,"scan_profile":"deps","critical_count":0}},"capability_facts":{"mcp":{"source":"repo_scan","observed_at":"2026-09-18T08:36:03.036Z","server_manifest":false},"scan":{"source":"repo_scan","observed_at":"2026-09-18T08:36:03.036Z"},"deploy":{"source":"dockerfile:Dockerfile","self_host":true,"observed_at":"2026-09-18T08:36:03.036Z","managed_saas":false},"has_cli":{"value":true,"source":"package.json:bin|scripts","observed_at":"2026-09-18T08:36:03.036Z"},"languages":{"value":["go","javascript"],"source":"github.language+package.json","observed_at":"2026-09-18T08:36:03.036Z"},"has_docker":{"value":true,"source":"dockerfile:Dockerfile","observed_at":"2026-09-18T08:36:03.036Z"},"license_spdx":{"value":"Other","source":"github.license","observed_at":"2026-09-18T08:36:03.036Z"}},"decision_facts":{"hosting":null,"pricing":{"model":"freemium","summary":"The skill, Agent SDK, and initializer are free under MIT license.
