NYDH puts API checks, test cases, automation and release gates in one workspace. Every pass and every fail keeps its evidence, so the call to ship is never a guess.
Explore five real app screens. Select a view below, or open the image for a closer look.
Track run performance, test cases and project activity.
See coverage gaps, failed checks and open bugs together.
Filter run results and export evidence for your team.
Create Playwright steps and export tests for local or CI execution.
Review detected page elements before adding them to your test.
Interactive examples use simulated runs and AI responses. The JSON formatter works locally in this page; workspace data is created in the app.
Send a request, break it, watch the failure land in the inbox, re-run it, and see the release gate change. The three tabs are wired together.

Each step links to the one before it. When a run fails, you can follow it back to the test case and the requirement it was written for.
Write down what done means: one coupon per order.
Apply a second coupon. Expect 409 Conflict.
API Runner, a schedule or automation executes it.
Request, response, timing and screenshots stay with the run.
Gates read from real results, so ready means ready.
Explore what you can do inside NYDH, from everyday API checks to browser exports, team workflows and account controls.

Turn REQ-112, one coupon per order, into test cases.
Here are three cases for REQ-112. The third covers a race condition that is easy to miss.
NYDH AI drafts test cases from requirements, explains why a run failed, and suggests the edge case you skipped. You review everything before it is saved.
The free workspace has every module. Limits reset at the start of each UTC month. Paid billing is not switched on yet, so there is nothing to cancel.
Up to 2 projects per account, shared across your workspaces.
No card. Your data stays in your workspace.
The workspace runs in your browser. API checks and Toolbox tools are available there. Exported Playwright and Selenium tests need their dependencies installed locally or in CI.
Your workspaces, projects and results stay yours. Data is not shared between workspaces, and you can delete a project with all its cases and runs at any time.
NYDH runs saved API checks and records their evidence in Run History. Exported Playwright, Selenium, visual and accessibility suites run locally or in CI; their browser execution does not happen inside this landing page.
That project pauses execution until the next UTC month starts. Your other eligible project has its own allowance, and your saved data remains available.
Yes. Invite teammates to share projects, collections and run history, with viewer, member and admin roles.
Bring API checks, test cases, automation and release evidence into one workspace. It takes a minute and it's free.
