A screen recorder that never
asks you to trust us.

01Why MergeCam exists

Most screen recording tools want an account before you've even hit record. Some upload your clip to a server just to let you download it back. MergeCam skips all of that — it's built on the idea that recording your own screen shouldn't require handing your video to anyone.

There is no login, no upload, and no server processing your video — not because we've hidden it well, but because that infrastructure simply doesn't exist in this product.

02How it actually works

When you click Start Recording, your browser asks where to save the file before anything else happens. From there, MergeCam uses the browser's own built-in recording, camera, and audio APIs to capture your screen, mic, and webcam, merges them together, and streams the result directly to that file on your disk — a few seconds at a time, so nothing builds up in memory even on long recordings.

The webcam bubble you see while recording is composited onto the video using a background Web Worker, which keeps the actual drawing work off the main thread so your recording stays smooth even during long sessions.

03What "zero server cost" actually means

MergeCam is hosted as a static site — plain HTML, CSS, and JavaScript, with no backend, no database, and no video processing pipeline. That's not a cost-cutting compromise; it's the entire design. Because there's no server doing the work, there's no server bill that scales with usage — which is also why MergeCam can stay free without a "pro" tier waiting behind a paywall.

04What to expect

MergeCam currently works in Chrome and Edge on desktop, since it relies on browser APIs that Firefox and Safari haven't implemented yet. It's a small, focused tool — not a full editing suite — and that's intentional. It does one thing: record your screen, cleanly, without asking anything of you first.
