Tada

About

What is Tada?

Tada is an automated QA assistant for AI-written code. It works through a feature in a real browser like a QA engineer, posts a pass or a block on the pull request, and records the walkthrough. Its home is taada.dev, spelled t-a-a-d-a dot dev, with two a's.

What Tada does

  1. You or your coding agent opens a pull request, and your preview deploys.
  2. Tada opens that preview in a real browser and follows the flows in your repository, one step at a time.
  3. Each step names something that must appear on screen. If it never appears, the check on the pull request fails and you get the frame where it broke.
  4. If every step holds, the check passes and you get a recording anyone can watch without logging in.

Mark the check required in branch protection and a failed run stops the merge, the same way your CI already does. People still decide what ships, and you can always override.

Who it is for

Founders, vibe coders, contractors and agencies shipping code written with AI tools such as Claude Code, Cursor and Copilot. With a QA team, Tada is a second pair of hands. Without one, it is the QA.

What Tada is not

  • Not a code reviewer. It does not read your diff. It opens the app and uses the feature.
  • Not a test runner for your CI alone. The result is made to travel: a recording for a pass, the failing frame for a block.
  • No AI decides the result. A run follows your flow files step by step, so the same flow gives a comparable result every time.

Where it runs

Tada's servers run every check. If your app is on your own computer, the Tada tool opens a temporary tunnel for the length of the run so the check can reach it.

What it costs

You pay per run, never per seat, so your whole team can watch for free. The Free plan includes 40 runs a month. See pricing for the paid plans.

Other things called Tada

Other projects share the name and are not connected to this one: TaaDa, an Android Auto app for Tesla cars, and TAADA, a tool used in reading research.
