Open Source Screen Recorder
A screen recorder captures whatever happens to be on display - an API token in a terminal, a customer's record in a bug report, an unreleased interface - so the question of where the file lands after you stop recording matters as much as the resolution. Cloud recorders answer that question by uploading first and asking later. The open source tools here can write straight to local disk in standard formats with no account and no upload in the middle, so the only copy of a sensitive capture is the one you decide to share. Several also self-host the whole share-and-review workflow when you do want links, on infrastructure you control.

Our picks
Match the recorder to your platform and to whether you need a local capture or a shareable link.
Best for high-quality recording and streaming: OBS Studio OBS Studio captures, composites, encodes, records, and streams from one application, with scenes that mix windows, displays, cameras, and capture cards plus per-source filters. It records locally with H264/AAC and streams to Twitch and YouTube, and studio mode previews scenes before they go live. It is the most capable option here for multi-source layouts.
Best self-hosted Loom alternative: Cap Cap records screen, camera, and microphone, then shares a link, exports a video, or keeps recordings local. It can run on Cap Cloud, your own S3-compatible storage, or full self-hosting with Docker Compose, so a team can own the whole share-and-review workflow, including comments, transcripts, and analytics.
Best Windows capture-and-share tool: ShareX ShareX captures or records any region of the screen with one key press, then runs annotation and effects before sending the result to a destination you choose. It adds scrolling screenshots, OCR, GIF recording, and custom uploaders that target any HTTP service, with command-line and hotkey control for repeatable capture-and-upload workflows on Windows.
Best simple recorder for Linux: Kooha Kooha is a distraction-free Linux recorder built for starting a capture without much setup. It records microphone or desktop audio, captures a monitor or region, and exports WebM, MP4, GIF, or Matroska. Built on GTK4 with PipeWire and xdg-desktop-portal, it handles modern Wayland sessions cleanly and ships as a sandboxed Flatpak.
Choosing a screen recorder for your platform and workflow
Two things narrow the field before any feature comparison: your operating system and what you actually do with the recording. Several strong tools are Windows-only, including ShareX and ScreenToGif, while Kooha is built specifically for modern Linux and vokoscreenNG spans Windows and Linux. On Linux the deeper question is your display server: capture behaves differently under Wayland and X11, so a recorder that leans on desktop portals, as Kooha does through PipeWire and xdg-desktop-portal, will work where an older X11-style grabber shows a black screen.
After platform, split the job into local capture versus share-and-review. For quick tutorials, bug reports, and GIFs, a local-first tool is enough: OBS Studio is the heavyweight for high-quality recording and streaming with scene compositing, ShareX pairs capture with annotation and upload automation on Windows, and ScreenToGif specializes in short GIF, APNG, and video clips. If your team wants Loom-style links, comments, and viewer analytics, Cap and Screenity provide that, and both can run privacy-first: Cap self-hosts the whole workflow with Docker and your own S3 storage, and Screenity runs local-only as a browser extension.
Treat audio and the exit path as their own checks. Confirm the recorder lets you pick microphone, system audio, or both, and that sync holds over a long capture, since privacy often means muting an app or excluding notification sounds. Then verify what happens after you stop: standard container formats, predictable file naming, clean recovery from an interrupted session, and hotkey or command-line control. The raw recordings stay useful outside the app only if they were written in a format anything can open.

Frequently asked questions
Which of these recorders runs on my operating system?+
Platform narrows the list fast. ShareX and ScreenToGif are Windows-only; Kooha targets modern Linux; vokoscreenNG covers Windows and Linux. OBS Studio runs natively on Windows, macOS, and Linux, Cap covers macOS and Windows with a web dashboard, and Screenity runs anywhere Chrome does as a browser extension. Decide the platform first, because a tool built for another desktop stack will not simply port over.
Does it matter whether my Linux desktop uses Wayland or X11?+
It matters a lot. Under Wayland, screen capture goes through desktop portals and permissions rather than direct grabbing, so an older X11-style recorder may show a black screen, miss windows, or drop the cursor. Kooha is built around PipeWire and xdg-desktop-portal specifically for this, and vokoscreenNG needs PipeWire and the GStreamer portal plugin for Wayland. If you switch compositors, test both session types rather than assuming.
Which tool replaces a Loom-style share-and-review workflow?+
Cap and Screenity both aim at that use. Cap records screen, camera, and microphone, then shares a link, and adds comments, transcripts, and viewer analytics; it can run on Cap Cloud, your own S3 storage, or full self-hosting with Docker. Screenity records and edits in the browser and can save to Google Drive. If owning the whole pipeline matters, Cap's self-hosting is the more complete answer.
Can these tools capture system audio and microphone at once?+
Many can, but the details vary by platform and audio stack. Kooha records microphone, desktop audio, or both; Screenity captures microphone or internal audio with push-to-talk; and vokoscreenNG takes audio from multiple sources. Look for separate source selection and per-source control, and if system audio needs a virtual device, test it before relying on it for a call or webinar. Check whether the final file keeps tracks separate.
What is the best way to record a quick GIF or bug report?+
For short, silent UI loops, ScreenToGif is purpose-built: it records a region, webcam, or sketchboard and edits frames before saving as GIF, APNG, video, or PNG. On Windows, ShareX also records GIFs and pairs capture with annotation and one-key upload. GIFs produce larger files and carry no audio, so for anything longer, a standard video container plays more reliably and stays smaller.
How do I keep sensitive recordings from leaving my machine?+
Favor a recorder that saves locally by default and makes any network feature explicit. Screenity can run in a local-only mode with no API calls or sign-in, and Cap can be fully self-hosted so recordings never touch a third party. Check where temporary files are written and whether any upload needs an account. Because captures often show passwords or customer data in the background, hotkeys to pause and region capture are practical controls.
Is OBS Studio too much for simple screen recording?+
It can be. OBS Studio is a streaming and compositing powerhouse built around scenes, multiple sources, filters, and efficient real-time encoding, which is more than a quick tutorial needs. If you just want to start a capture with minimal setup, Kooha on Linux or ShareX on Windows is faster to reach for. Choose OBS when you need multi-source scenes, high-quality encoding, or to stream and record at once.
