Kap
MITKap is an open-source macOS screen recorder that replaces Loom for capturing local video and GIFs with zero subscription fees and built-in trimming.

Overview
Kap uses web technologies wrapped in an Electron container to capture macOS desktops directly from the menu bar without routing video through external servers. The project pairs an uncluttered capture frame with local conversion utilities to produce trimmed MP4, WebM, and GIF files on your machine. Every recording remains on local disk unless you choose to upload it.
Why Kap instead of Loom
Loom organizes screen recording around a cloud dashboard: every capture uploads automatically, generates a shareable link, and provides automated transcripts alongside a floating webcam circle. That pipeline works well for remote presentations, but it introduces monthly seat fees, strict recording length caps on unpaid accounts, and cloud privacy concerns. Kap removes the cloud dependency, anchoring capture to the macOS menu bar. You select a window or custom area, record with no time limits, and finish without creating an account or waiting on server processing queues.
For daily communication, Kap fits into local work habits. Instead of sending colleagues to an external web page with comments and viewer tracking, Kap lets you trim the clip immediately and export an MP4 or animated GIF directly to your clipboard or desktop. The resulting file drops straight into Slack, email, or tickets. Loom wins when you need viewer analytics and interactive discussions, but Kap offers a faster, distraction-free workflow whenever you simply need to show what happened on your screen.
What it does well
- Menu bar residency: Kap stays in the macOS top bar, letting you start a recording in two clicks without keeping a heavy window open.
- Flexible framing: Drag a frame over any desktop region, snap to an active window, or pick standard aspect ratios like 16:9 and 1:1.
- Built-in trimming: An inline timeline lets you cut unwanted seconds from the start and finish before saving.
- Direct GIF and MP4 exports: Save lightweight animated GIFs or standard MP4 videos to drop directly into chat, support tickets, and slides.
- Mouse click highlights: Optional visual circles appear around clicks, helping viewers follow step-by-step actions without extra editing.
- Optional voiceover: Record voice explanations through your internal or external microphone alongside screen video.
Limitations
- macOS exclusivity: Kap runs only on macOS 12 Monterey or later, with no versions for Windows or Linux.
