Session Recordings

We’ve completely rebuilt session recordings from the ground up.

Instead of DOM-based replay, Browserbase now records what the browser actually renders using a CDP-based screencast. This makes replays deterministic, accurate, and trustworthy.

What’s new:

• Pixel-accurate screen recordings (no DOM reconstruction)
• Event-driven frame capture (records only when the screen changes)
• Asynchronous, constant-time video encoding using HLS
• Seamless multi-tab playback with a shared global timeline
• Secure, signed segment delivery with CDN enforcement
• Just-in-time encoding to keep costs low and playback fast

If you tried our old session replays and lost trust in them, this rebuild is for you.
