Graft was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 5 topic tags (ai-agents, anthropic, claude-code, developer-tools), so they are genuine substitutes rather than adjacent tools.
Two open source projects, one decision. Both are free and self-hostable — the differences are community size, license terms, language stack and release pace.

About ECC
ECC is an MIT licensed open source agent harness performance optimization system that gives AI coding agents a coordinated engineering workflow — plan, test, implement, review, verify, remember, improve — for developers working in Claude Code, Codex, OpenCode, Cursor, and other harnesses.
About Graft
Graft is an open source TypeScript CLI and MCP server that builds a readable, file based knowledge graph of your repository so coding agents such as Claude Code, Cursor, Codex and Gemini start each task already oriented instead of re exploring the code from scratch.
