TabCaster Features

The screen recorder that gets out of your way

No sign-up. No cloud upload. No per-minute limits. TabCaster records your tab, captures your voice, and drops the file in Downloads — ready to share in under a minute.

Tab and desktop recording

Record any browser tab or your full screen. Switch sources before you start — no app switching, no audio routing setup.

Privacy blur built in

Click any element to blur it before recording. Auto Blur detects emails, passwords, credit cards, SSNs, API keys, and more — baked into the video, not added after.

No cloud. No account.

Recordings are processed entirely in your browser and saved straight to your Downloads folder. Nothing is sent to a server.

MP4 and WebM export

Record to MP4 (H.264) for universal compatibility or WebM (VP9) for smaller files. The extension picks the best codec your browser supports.

Microphone and tab audio

Tab audio is captured automatically. Toggle the mic to add voiceover narration — both tracks are mixed into the recording.

Pause, resume, keyboard shortcut

Pause mid-recording without losing footage. Use Cmd+Shift+U (Mac) or Ctrl+Shift+U to start and stop without touching the mouse.

Built for practical recording

From quick bug reports to polished demos

Use TabCaster when the thing you need to explain already lives in a browser tab. Open the extension, choose your audio settings, record, and save a WebM file you can send or edit.
