Cq vs CRAG
Which one should you ship with? Here is the side-by-side panel verdict, pricing read, reviewer split, and community vote comparison.

Cq
Stack Overflow for AI coding agents, by Mozilla AI

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.
Developer Tools
CRAG
One governance file, compiled into every AI coding tool's format

CRAG is a governance compiler for AI-assisted codebases. The premise is simple but genuinely useful: you write one canonical `governance.md` file describing your project's coding standards, security requirements, and AI behavior rules — then CRAG compiles it into 12 target formats simultaneously: GitHub Actions workflows, pre-commit hooks, Cursor rules, GitHub Copilot instructions, Cline configs, Windsurf rules, Amazon Q Developer settings, and more. As development teams adopt multiple AI coding assistants — which is nearly universal now — maintaining separate rule sets for each tool becomes a synchronization nightmare. A security policy you update in your Cursor rules doesn't automatically propagate to your Copilot instructions or your CI checks. CRAG treats governance as a single source of truth and the tool-specific configs as build artifacts. The compiler is zero-dependency, deterministic, and SHA-verifies each output for auditability. It's early — 8 stars at the time of posting — but the problem it addresses is real and growing in proportion to how many AI coding tools a team runs simultaneously.
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.”
“Maintaining separate .cursorrules, copilot instructions, and CI configs is already a real headache on teams using 3+ AI tools. The single-source-of-truth approach is architecturally correct and the zero-dependency design keeps it lightweight. Early, but the concept is solid — I'd pilot this on a team project immediately.”
“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 governance tooling is nascent but will be critical infrastructure within 2 years. The pattern of 'define once, compile everywhere' is how we handle configuration drift in infrastructure (Terraform, Ansible) — applying it to AI behavior rules makes sense. CRAG is an early prototype of what will eventually be a standard enterprise workflow.”
“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?”
“Each AI coding tool has subtly different semantics for what rules actually do — what a Cursor rule enforces versus what a Copilot instruction suggests are meaningfully different. Compiling from a single source risks giving false confidence that all tools are behaving consistently when they're not. The abstraction may leak badly in practice.”
“As a solo creator I only use one or two AI coding tools at a time, so the multi-tool synchronization problem doesn't hit me hard enough to add another tool to my workflow. This feels aimed squarely at engineering teams rather than individuals.”
