Regresco for writing and running browser regression tests
Regresco turns a plain-language test into a saved browser flow and runs it on a staging site. An MCP connection can give coding agents scoped access.
Regresco helps development teams check whether a change broke a workflow in a web app. It can draft test steps from plain language and run saved flows in a managed browser. The publisher also offers an MCP connection for coding agents that need to create or inspect regression tests.
Building a test flow
The product page describes a workflow in which a team connects a staging site and saves flows for actions it wants to repeat. The documentation lists several ways to make a flow: describe a test, let AI Generate propose flows, import existing Playwright tests or build the steps by hand. A developer can review and edit a generated flow before treating it as a release check.
Running and reviewing results
Regresco says its workers run flows in Chromium against the staging environment. Results can include screenshots, traces and console logs, and the product can compare a run with a baseline. The docs warn that bot protection such as a CAPTCHA can stop the cloud browser before it reaches the page. Treat a blocked run separately from a report that a workflow broke.
An MCP client can read results and, with the appropriate permission, create or edit flows and start runs. The publisher says its MCP tools cannot delete records. A team can grant read access first if its main goal is to let an agent interpret a failure.
Plans and practical limits
The Free plan includes one project and 20 runs per month. Regresco lists more projects and runs on paid plans, with a priority queue on Business. The publisher says runs started by an agent count toward the same plan limits as other runs. Start with a representative staging flow and check what the test actually asserts before depending on it in a release process.

Frequently asked questions
Can Regresco use existing Playwright tests?
Yes. The documentation lists importing Playwright tests as one way to create a flow. You can also edit a flow manually.
Official sourceCan a connected coding agent delete flows?
The publisher says nothing can be deleted through MCP. The connection can be scoped for reading, editing projects and flows, or starting runs.
Official sourceDo agent-triggered test runs use the same monthly allowance?
Yes. Regresco says runs started by an agent count toward the monthly run allowance, just like other runs.
