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.

Cypress provides fast, reliable E2E testing with time travel debugging and real-time reloading. Chromium-only for a long time but now supports Firefox and WebKit.
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.”
“Playwright has surpassed Cypress in capabilities. Multi-browser, auto-waiting, and trace viewer are all better in Playwright.”
“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.”
“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?”
“Was the best E2E framework but Playwright has taken the lead. The cloud pricing for CI is expensive.”
“The test runner UI and time-travel debugging are the most intuitive of any testing tool.”
