FAQ
- What is the best free open-source BrowserStack alternative?
- The best open-source alternative to BrowserStack is Playwright or Selenium, self-hosted on Railway. Browser tests you run. Playwright is Apache-2.0; Selenium is Apache-2.0 — BrowserStack without the parallel-session meter.
- Is it free?
- The Playwright / Selenium licenses are open source or fair-code. You still pay hosting (Railway or any VPS) and any APIs the stack calls. There is no BrowserStack seat or task bill on this path.
- Can I migrate from BrowserStack?
- Yes. Start with the workflows or data you actually use, then cut over. The Playwright / Selenium stack page has the agent prompt and the cost table; most teams rebuild the slice that matters and leave old BrowserStack links until they expire.
- How do I deploy it?
- Open the Playwright / Selenium stack, copy the agent prompt, and deploy on Railway (one service, PORT, and a volume when the app needs disk). These are CI jobs (and optionally a Selenium Grid). Playwright needs browser dependencies in the runner image. Grid is a set of nodes, not a single HTTP app. No one-click device-farm template in this repo — Start on Railway only if you also host Grid. Code quality stays on /stacks/sonarqube-lint.
- What does this replace?
