In their words

PreFlight is a No-code web testing tool for anyone. Preflight is 20x faster than writing Selenium and Cypress tests. Maintaining Selenium/Cypress tests is also a big challenge. Preflight solves this problem by understanding how users understand any page and adapt to the changes and update the selectors if the test passes. It's also super easy to set up end-to-end tests that depend on each other with Preflight's Workflow feature. You can orchestrate which test should run after another. Creating API tests has never been so easy. Preflight prepopulates API tests from UI tests' network calls. So, you can set up API tests in minutes.

Is this you?

If you're behind Preflight: acceptance into a YC batch is one of the few weeks a young company gets looked up by people who matter — investors, other founders, press. FoxPlug turns the commits, deploys, and releases you're already making into that story automatically, so anyone who looks finds something current. FoxChat puts a guide on your own site so the people YC's own page just sent you don't read one line and leave.

Sourced from the company's Y Combinator directory entry.
