Tiden

Tiden is a verification tool for engineering teams that ship code written by AI coding agents such as Claude Code, Cursor, Copilot and Codex. It reads a codebase, writes down each behaviour the product is meant to have as a versioned spec kept beside the code, and marks the specs that no test yet proves. When an agent starts work on a change, Tiden turns the request into a list of promises, generates tests for them and will not let the session close while a promise is still open. Each pull request then shows what was promised and which tests prove it, while code review stays with the team's own reviewer. Errors in production are traced back to the release that caused them. The product comes from Qase, Inc., the company behind the Qase test-management platform, and was launched on Product Hunt on 14 October 2026. Its pricing page lists a Starter plan at $49 a month for one product, up to three repositories and 25 verified changes, a Team plan at $199 per product per month with SAML single sign-on, and custom Enterprise terms that include a self-hosted option. Both paid plans start with a 14-day free trial.

Not yet independently verified: The launch date rests on the maker's Product Hunt launch of 14 October 2026, which its own site links to. Capabilities and prices come from the maker's own pages and were not independently checked. We will update this when it can be confirmed, and remove this note.
