Bulletproof Dash apps.
Handoff-ready for your AI.

A callback-aware Playwright harness for your Plotly Dash dashboards. It waits for the dynamic loads instead of guessing, asserts the numbers, and returns a clean release receipt on every pull request. Built to be run and extended by your team and your coding agents, without you.

Every pull request, proven before it merges.

Pick a dashboard and run the check. The harness waits for the callbacks to settle instead of sleeping on a timer, asserts the rendered numbers against a golden dataset, and hands back a receipt your team and your agents can read at a glance.
