Weffe review
A focused Linux command-line tool for adding overlays and blur to a virtual-camera feed.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Weffe is an open-source command-line webcam effects tool for Linux, aimed at solo users and small teams who want a customized feed in video calls. It processes webcam video with ffmpeg and v4l2loopback, then sends the result to a virtual camera. That makes it a focused option for people who want effects in compatible calling apps rather than a broad webcam management suite.
Its feature set centers on changing what appears in the feed: users can blur the outer area with selectable focus shapes, overlay images, add configurable top and bottom text, rotate the stream continuously or according to a time-based function, and loop a video file. The virtual camera is listed for use with Zoom, Webex, and Google Meet. Weffe does not include recording or camera controls, so it is better suited to preparing a live call feed than capturing or managing camera hardware.
The project is described as open source and self-hosted, with a free plan. Installation instructions cover Arch-based and other Linux distributions, while a beta option can monitor whether an application is using the virtual camera and run on demand. That option may appeal to users who want Weffe active only when a call app needs the feed, though its beta status makes it a less settled part of the offering. Choose Weffe for lightweight Linux overlays and virtual-camera output; look elsewhere if you need a graphical workflow, recording, or support beyond Linux.
