(TYAN) is, who it's built for, and how it helps you verify that critical application journeys work in production. TYAN is an automated flow verification platform that confirms your application's most important user journeys are working end-to-end in production — not in a sandbox, not against mocks, and not by eyeballing a staging environment. Unit tests tell you that individual functions behave correctly. Visual checks tell you that a page renders. TYAN tells you that a real user can actually complete the journey from start to finish, right now, in under five minutes. ## What is TYAN? Most testing tools stop at the code level or the visual layer. TYAN goes further by executing complete user journeys — sign up, log in, submit a form, complete a checkout — against your live production environment using a real browser. Every run produces a pass/fail result with step-by-step evidence, so you always know exactly where a journey breaks and why. You define flows once using the no-code and low-code flow builder, then run them manually, on a schedule, or triggered from your CI/CD pipeline. When a flow fails, you get an immediate alert with screenshots and a full step trace so you can diagnose and fix the problem before it costs you users or revenue. ## Who is TYAN for? TYAN is built for the people who own outcomes, not just code: * **CTOs** who need confidence that the product works before a release goes out and visibility when something breaks in production * **Solo founders** who can't afford to spend hours manually clicking through their app after every deployment * **Indie hackers** who want automated safety nets around their most revenue-critical flows without hiring a QA team * **Engineers** who want fast, repeatable acceptance gates they can tie directly to requirements and run on every merge ## Core use cases ### Ship verification Before you push a release, run your critical flows to confirm they still work. TYAN gives you a definitive green or red signal in five minutes, so you ship with confidence instead of crossed fingers. No manual retesting required after every change. ### Pipeline monitoring Your marketing funnel only works if every step of the prospect journey — from landing page to lead capture or booking — is actually functioning. TYAN continuously verifies that the complete path is healthy and alerts you the moment a broken step starts costing you pipeline. ### Acceptance testing Turn written requirements into repeatable, shareable acceptance flows. Instead of handing a spec to QA and waiting days for results, define the acceptance criteria as a TYAN flow and use it as a gate throughout development. When the flow passes, the feature is done. ### Delivery verification When a development team ships a project, independently verify that the delivered software does what was agreed. Run the acceptance flows against the production deployment and get an objective, evidence-backed report — no ambiguity, no back-and-forth. Build and run your first flow in under five minutes. Understand the architecture behind flow execution and monitoring.
