Screenshots and screen recordings with blur, pixelate, and block redaction, processed in your browser.

UI testing in Testnir
Review a live page, leave the evidence where it belongs.
Open a page inside Testnir, click to leave threaded comments, and capture screenshots or recordings with sensitive details redacted before you share.
- Click-to-comment threads on a live page
- Screenshots and screen recordings with redaction
- Invite a reviewer by email and revoke access anytime
What you can do today
- Review any public URL with threaded, positioned comments
- Invite a reviewer by email, with access you can revoke
- Record your screen, window, or tab with audio and a webcam overlay
- Annotate, redact, and beautify screenshots, then attach them to a bug report
- Trim and export recordings as MP4 or WebM without uploading them
Scope
- Reviews and captures are manual workflows; scripted UI automation is not part of the product today
- Pages that block embedding can be reviewed from a snapshot instead
