TabCaster is a Chrome extension that records your browser tab or full screen to MP4 or WebM with microphone audio. Built-in privacy blur hides sensitive data before recording starts. Recordings are saved directly to your device — no cloud uploads, no account, no tracking.

Everything You Need to Record

Screen recording built for privacy. Record your tab or desktop, blur sensitive content, and save locally — no setup required.

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.

How It Works

From install to finished recording in five steps — blur first, record second, save locally.

Frequently Asked Questions

Does TabCaster upload my recordings anywhere?
No. All recording is processed locally in your browser using the Web MediaRecorder API. The video is saved directly to your device and never sent to any server.
Do I need an account to use TabCaster?
No account is needed to record. An email is only required if you purchase Pro (via Stripe) or restore a Pro license on a new device.
What video formats can I record in?
TabCaster supports WebM (VP9 codec, default) and MP4 (H.264). The extension automatically selects the best supported codec for your browser.
What is the difference between Free and Pro?
Free includes unlimited tab and desktop recording, WebM and MP4 export, microphone audio, pause/resume, manual blur, and auto-blur for emails and passwords. Pro removes the watermark, unlocks 25 Mbps and 50 Mbps video quality, and adds advanced auto-blur for credit cards, SSNs, phone numbers, IP addresses, and API keys. Pro is a one-time $29 payment.
How does the privacy blur work?
Click the Blur button in the popup, then click any element on the page to blur it. The blur is applied using CSS before the screen capture begins, so it is baked into the recorded video. Auto Blur can also scan the page automatically for sensitive data patterns and blur them without any clicks.
Is Pro a subscription?
No. Pro is a one-time $29 payment. You pay once and keep Pro on that Chrome profile forever. Your license is tied to your email and can be restored on any device from the Settings page.
Can I record my microphone?
Yes. Toggle the microphone switch in the popup before starting. Tab audio and microphone audio are both captured and mixed into the recording.
Is there a recording time limit?
TabCaster does not impose a recording time limit. Available memory, storage, and browser behavior can affect very long recordings.

Record your tab or screen. Stays on your device.
