Capture - Multi-Stream Screen & Camera Recorder

What makes it different

One panel for what used to take a pile of apps and devices.

Recording a screen, a webcam, a phone, and a couple of mics normally means a separate tool for each - then wrestling the files together afterward. Capture runs every stream from a single panel, recording them at once while keeping each as its own independent track.

Multiple streams

Record everything at once - each on its own track

Webcam, laptop screen, external monitors, a single browser tab, even a connected phone. Every source is an independent video track you start, pause, and finish on its own - and microphone, external mic, and desktop audio come in as their own separate tracks too.

Screens, cameras, tabs and phones captured in parallel
Per-track start / pause / resume / finish
Desktop and mic audio kept as distinct tracks

Merge export

Mix and match audio onto video at export

Don't settle for one baked-in mix. In merge mode you assign one or more audio tracks to each video, then render - so the screencast gets the mic and desktop audio while the camera gets just the lav. Prefer it simpler? Single combines one video with all audio, and Export All writes every track on its own.

Assign any combination of audio tracks per video
Three modes: Single · Export All · Merge
Muxed locally with ffmpeg.wasm - nothing uploaded

Periodic export

Auto-save clips while you keep recording

Turn on periodic export and Capture quietly downloads a zip every few seconds - a fresh clip from each recording track since the last one - without ever stopping the recording. A safety net for long sessions, and an easy way to hand off footage as you go.

Set any interval (from 10s up)
One zip per tick, every track included
Recording never pauses or drops a frame

Time-lapse modes

Compress hours into seconds, per track

Give any track a time-lapse on export. Pick a constant speed - say compress 2 hours down to 30 seconds - or set a target length and let Capture fit the speed to it. Audio is sped to match, so a long build or stream becomes a tight, watchable clip.

Static (constant speed) or Dynamic (fit to length)
Audio time-stretched to stay in sync

Free & open source

Free, private, and yours to fork

Capture runs entirely in your browser - no install, no account, nothing uploaded. Recordings stay on your machine. It's plain HTML, CSS, and JavaScript with no build step and no framework, released open source: read it, fork it, self-host it.

Local-only - your footage never leaves the device
No sign-up, no paywall, no telemetry
Open source - clone and host it yourself

How it compares

One tool where others need a stack

Capturing several screens, cameras, and audio sources independently usually means juggling plugins, paid apps, or a cloud service. Here's where Capture lands.
