Kerno

Kerno is an AI backend runtime QA engine for teams that use coding agents. It runs locally against the real application stack and tests critical user flows end to end, aiming to catch runtime and security bugs inside the agent loop before changes merge. It maps a codebase and its entry points, tests each flow as one journey across APIs, re-runs every flow a change touches, and updates tests as the product changes. Contract and schema validation is also listed.

A CI integration works as a merge gate that runs on every pull request and drops a report on it. The site says it works with any CI that runs a container, and lists GitHub Actions, GitLab CI, Jenkins, CircleCI, Buildkite and Azure Pipelines. The local stack shown includes Postgres, ClickHouse and Kafka. Security testing runs inside the agent's loop against live services. Tests run from what is already committed, so the same commit returns the same verdict.

Pricing is per developer. Community is $0 per dev per month with 30 test runs per month, 1 repository and 1 user. Pro is $50 per dev per month, or $37.50 per dev per month billed yearly at $450, with unlimited test runs, repositories and users. Enterprise is custom and adds SSO and SAML, self-hosting, audit logs and data controls. Qualified open source projects use Kerno free, and pre-Series A startups get 50% off.

Check a few details before buying. CI integration is listed under Pro rather than Community, and every scenario run counts as one test run against the Community limit of 30. Prices are in dollars, with no rupee pricing. Kerno is operated by FYCK Limited, a company registered in Ireland, and the terms are governed by the laws of Ireland. Enterprise buyers can ask for a custom DPA and custom invoicing and payment terms.
