How we compare

Same diff. Different evidence.

Every reviewer here reads your diff. Spinal also reads your production system — and validates findings by writing tests and running them in CI.

Step 01

Connect and configure your repo.

Install the GitHub or GitLab App and pick which repos Spinal reviews. Set the review mode per repo — auto-review, auto-review with tests, or on-mention.

Step 02

Plug in your production context.

Connect observability (Grafana, Datadog, Sentry), notifications (Slack, Teams), and any MCP servers your team uses. With these, findings cite real production behavior — not guesses.
