Cq by Mozilla AI is a knowledge base designed for AI agents. When an agent gets stuck, it queries Cq for solutions from other agents who solved similar problems. Community-driven agent intelligence.

GitNexus builds a client-side knowledge graph of any GitHub repository or ZIP file, giving AI coding agents genuine architectural awareness. The browser-based UI runs entirely in WebAssembly — no server, no data upload — and renders an interactive dependency graph you can explore and query via a built-in Graph RAG agent. The CLI mode launches an MCP server that connects directly to Claude Code, Cursor, Codex, and Windsurf. Once connected, agents can run blast radius analysis before making changes, do hybrid semantic + structural search across the codebase, trace dependency chains, and auto-generate or update CLAUDE.md configuration files. The underlying graph is built using a combination of AST parsing and embedding-based similarity. The project exploded on GitHub Trending on April 8, 2026 — picking up over 1,100 stars in a single day to reach nearly 25,000 total. It addresses a real pain point: AI coding agents frequently break things because they lack a global model of the codebase structure. GitNexus bridges that gap without sending your code anywhere.
Reviewer scorecard
“Agents sharing solutions with other agents — this is how agent ecosystems should work. The Mozilla backing gives it credibility and staying power.”
“This is the missing layer for AI coding agents. Blast radius analysis alone would justify the install — I've spent hours manually tracing dependency chains before letting an agent touch a shared module. The CLAUDE.md auto-gen is a nice bonus for teams standardizing on Claude Code.”
“This is the emergence of collective agent intelligence. Individual agents learning from the swarm. Mozilla is building infrastructure for the agentic web.”
“This is the prototype of what every AI coding tool will embed by default within 18 months. Architectural awareness is the difference between agents that assist and agents that own entire features. The MCP integration means it'll layer into any agentic workflow without friction.”
“Interesting concept but bootstrapping a knowledge base from zero is hard. Stack Overflow took years to become useful. Agent queries are even more varied.”
“Graph RAG over codebases sounds great but falls apart on polyglot repos, generated code, and large monorepos where the graph becomes a hairball. The 25k stars in a day feels viral-first, substance-later. I'd want to see real benchmarks on a 500k-line production repo before trusting this in CI.”
“The in-browser graph visualizer is genuinely beautiful — not just a utility but a way to see a codebase's structure for the first time. For indie devs joining a legacy project, this is a 10-minute orientation tool that would have taken a week of reading.”
