What Is Kap and What Can You Do With This Open-Source Screen Recorder?

Kap is an open-source screen recorder for macOS, built with web technology and available from getkap.co. It records your screen and exports the result as GIF, MP4, WebM, or APNG, with optional audio, click highlighting, and trimming. It fits macOS users who want a lightweight, open-source capture tool and are running macOS 12 or later; if you are on Windows, Linux, or an older Mac, Kap is not an option.

What Kap actually does

The core workflow is simple: capture the screen, optionally clean up the recording, then export in a format that suits where it will be shared.

• Recording: captures screen activity on macOS. The site describes it as "more quality, less noise," positioning it for clean, presentable output rather than raw capture.
• Audio: optional audio can be included in the export, so you can narrate or capture system sound when needed.
• Click highlighting: visual emphasis on clicks, useful for tutorials and walkthroughs where viewers need to follow the cursor.
• Trimming: cut the start and end (or unwanted sections) before exporting, so you don't have to open a separate editor for basic cleanup.
• Export formats: GIF, MP4, WebM, or APNG. GIF suits short loops and quick sharing; MP4 and WebM suit longer clips and web embedding; APNG is an animated PNG alternative to GIF.

Who it is built for

The site names designers, developers, and project managers as its users. That matches the feature set: short, annotated clips for bug reports, design feedback, and documentation, rather than long-form video production. If your task is "record a 20-second repro of a UI bug and paste it into a ticket," Kap's format options and click highlighting are directly relevant. If your task is editing a multi-hour recording with transitions and titles, Kap is a capture tool, not a full editor.

Integrations and sharing

Kap lists three sharing and deployment integrations on its site:

These are useful when your output is a short clip meant to live on the web. For example, a designer recording a hover-state animation can export a GIF and push it to Giphy, or a developer can deploy a demo clip alongside a Vercel-hosted project.

Before you install: two checks

1. macOS version. The site states macOS 12 or later is required. Confirm your version under System Settings before downloading.
2. Chip type. The download page offers separate builds for Apple (M1) and Apple (Intel). Pick the one matching your Mac to avoid running the wrong binary.

The project is open source, with the site pointing to GitHub for viewing and contributing. If you want to inspect the code, report issues, or extend it, that is where to go; the site also links to an Issues page and a License page.

How to decide

Choose Kap if you are on macOS 12+, want an open-source recorder, and your output is short clips for sharing, documentation, or bug reports in GIF, MP4, WebM, or APNG. Look elsewhere if you need Windows or Linux support, a full video editor, or long-form production features. The site does not publish pricing details, so check the download page and GitHub for the current terms rather than assuming it is free or requires an account.
