I m building ProMatte, a free, GPL-licensed OBS filter for removing, blurring, or replacing webcam backgrounds locally.
I started it because existing options can require an RTX GPU, a subscription, a green screen, or cloud processing. ProMatte runs on the user s own machine with no account, telemetry, or uploaded camera frames.
I m especially interested in hearing from OBS users:
What do you currently use for background removal?
Is performance, edge quality, hardware support, or setup the biggest issue?
Do you prefer transparent backgrounds, blur, or replacement backgrounds?
ProMatte is a free, open-source filter for OBS Studio that removes, blurs or replaces your webcam background in real time. It runs entirely on your own machine: no cloud, no account, no telemetry, and camera frames are never uploaded or saved.
It was built and tuned on a 2017 dual-core laptop with a GeForce 940MX, deliberately, so that the numbers behind it come from close to the worst case rather than from a workstation. Every performance figure published names the machine it was measured on.
