Serverless browser APIs hand you a page and nothing else. The playwright template gives you a full dedicated microVM — a real Chromium, a real filesystem for artifacts, and a public URL to watch the run live.
⬢
Real Chromium, baked in
The playwright template ships Chromium and the Playwright runtime pre-installed. No playwright install, no download wait, no missing system libraries.
▤
Full filesystem for artifacts
Write screenshots, PDFs, HAR files and scraped JSON anywhere on disk, then sb.download("/out","./results") pulls the whole directory back to your machine.
◉
Public preview URL
Launch a headed browser or a live viewer and open sb.url to watch the automation run in real time — handy for debugging flaky selectors. App preview guide →
◷
Trace + video capture
Playwright's tracing and video recording work out of the box. Save the trace.zip to disk, download it, and open it in the Playwright trace viewer locally.
