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.
Reviewer scorecard
“Free tier with no restrictions is remarkable. Completion quality rivals Copilot for most languages.”
“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.”
“Hard to argue with free. The enterprise features and Windsurf IDE show they have a real business model beyond the free tier.”
“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?”
“Giving away code completion to win IDE market share with Windsurf is a smart long-term play.”
“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.”
