comber

codecomber.io — every-click AI QA. comber walks every interactive state of your web app or API surface like a relentless user, and reports what's broken — on every preview deploy, before your users find it.

bash

npx comber check https://your-preview-url.example

That's the whole setup for a first run. With an Anthropic or OpenAI key, comber adds AI judgment on top of the crawl; without one, it runs in heuristic mode.

Ways to run it

CLI — npm i -g comber · package
CI Action — action.yml in this repo: crawl a preview deploy, upload the report, post a non-blocking PR comment, optionally gate on fail-severity findings. Works from GitHub Actions, GitLab CI, or any runner.
MCP server — comber-mcp: run QA checks from any MCP client (Claude, Cursor, and friends).
Hosted — app.codecomber.io: the managed dashboard — runs, history, connectors, and team billing. No infrastructure on your side.

Configuration

Start from comber.config.example.json. Connector setup (GitHub, GitLab, Slack, Jira, Linear, and more): docs/CONNECTORS.md.

Data handling

comber necessarily observes the surfaces it tests. What it captures, what it does with it, and what you control: docs/DATA_HANDLING.md.

Pricing

Self-hosting with your own AI key is free. The hosted dashboard and managed runs are usage-priced — codecomber.io.
