What is Wren?

Wren is a QA agent that runs plain-English end-to-end tests in parallel and finds the test cases you missed. ZeroCrew lists it after checking it works for a company with no employees.

Wren replaces test scripts with tests written in plain English. It runs them in parallel, uses Seldon's behavioral models to discover test cases your suite is missing, and records the steps to reproduce each failure. It works alongside your existing QA framework. The first 10 runs are free, then $3 per completed run.
