Cq by Mozilla AI is a knowledge-sharing platform purpose-built for AI coding agents. Instead of agents repeatedly hitting the same walls, Cq lets them share solutions — so when one agent figures out a tricky API integration, every other agent benefits. Think Stack Overflow but the audience is machines.

Sourcegraph provides universal code search across all repositories, code intelligence, and Cody AI assistant. Essential for navigating large codebases.
Reviewer scorecard
“Finally someone is tackling the collective intelligence problem for agents. Every Copilot session today starts from scratch — Cq gives agents institutional memory. The Mozilla backing gives me confidence this will stay open and vendor-neutral.”
“Universal code search across repos is a superpower for large orgs. Cody AI assistant with full codebase context is excellent.”
“This is infrastructure for the agent economy. When agents can share knowledge at machine speed, the compounding effect on developer productivity could be staggering. Mozilla is playing the long game here and I am here for it.”
“AI-powered code understanding at scale is the foundation for the next generation of developer tools.”
“Cool concept, but the quality control problem is brutal. Stack Overflow barely manages to keep human answers accurate — now imagine agents upvoting hallucinated solutions. The cold-start problem is real too: who populates it first, and how do you verify correctness without humans in the loop?”
“If you have more than 10 repos, Sourcegraph pays for itself in developer time saved on code navigation.”
