Best Mac Trackpad Edge Apps in 2026

The edge of a Mac trackpad used to be dead space. In 2026 it is a product category. Slidr, Haptiker, EdgeBar, Glisse, and a wave of open-source apps turn the left and right edges into volume and brightness sliders; some add keyboard backlight, app switching, media scrub, or haptic ticks.

We make TrackStudio, which includes edge controls but is a whole-surface app. This roundup ranks the edge-first apps on their own terms and names where each one is the better buy. TrackStudio is not ranked first.

What counts as an edge app?

An edge app starts a gesture only when one finger begins in a narrow strip along the trackpad edge. The gesture usually has to run along the edge, not across it, so normal scrolling and pointing still work. Good edge apps also ignore two-finger scrolls, typing, and touches that start in the middle of the pad.

The category splits into three groups: paid edge-only apps, free/open-source edge apps, and whole-surface apps that include edges as one feature. The first two are the subject of this page. The third is a different purchase.

The short list

Prices, trials, and macOS requirements checked on the vendors’ public pages on November 2, 2026. Regional pricing and taxes vary. “Not stated” means the vendor does not publish it.

1. Slidr — the best overall paid edge-only app

Slidr is the most established paid app in the category. Slide up or down the right edge for volume, the left edge for brightness. It shows the real macOS HUD, gives a haptic tick as the level changes, and supports external monitor brightness over DDC. There is also a three-finger middle click, fine control, side swapping, a bottom-quarter mode, typing detection, cursor freeze, and an optional modifier requirement.

It costs $4.99 one-time after a three-day trial and runs on macOS 12 or later. It is also included in Setapp. That is a short trial, so test it on your own trackpad before you rely on it.

Limits: edges only. No corners, custom areas, center gestures, per-app scenes, or media scrub. If you only want two sliders, that is not a weakness. It is the point.

2. Haptiker — the best four-edge control

Haptiker adds two edges that Slidr does not: the top edge controls keyboard backlight, and the bottom edge can switch apps. The right edge is volume, the left is brightness, and brightness follows the display under your cursor, including external monitors on Apple silicon over DDC/CI.

It costs $4.99 at the launch price, $7.99 regular, with a seven-day trial and a license for three Macs. It runs on macOS 12 or later, supports Apple silicon and Intel, and has strong gesture guards: a slide only counts when one finger starts on the edge and runs along it. Double-tap the volume edge to mute or jump to a preset; double-tap brightness for max, min, or a custom level.

Limits: edges only. No corners, custom areas, or per-app scenes. The bottom-edge app switcher is useful, but it is not the same as a per-app scene.

3. EdgeBar — the best cheap edge + media strip

EdgeBar is $5 one-time and runs on macOS 13 or later. It puts volume on the right edge and brightness on the left, adds a media strip on the bottom edge, quick mute by double-tapping the top-right corner, haptic feedback, fine control with Shift-Option, cursor freeze, bottom-quarter mode, and side swapping.

The trial is not stated on the vendor page. If you want a cheap edge app with a media strip and do not need per-app scenes, it is a sensible buy.

Limits: edges and media strip only. No corners, custom areas, or per-app scenes.

4. Glisse — the best free edge-only app

Glisse is free and open source under MIT, and it runs on macOS 13 or later. It does the core job well: left edge for brightness, right edge for volume, the real macOS HUD, haptic ticks, typing suppression, fine control, bottom-quarter mode, an optional modifier, pointer freeze, three-finger middle click, DDC for external displays, and launch at login.

The honest caveats matter. The build is ad-hoc signed, not notarized, so macOS will ask you to approve it. Accessibility permission resets on upgrade. The developer says external DDC is written but was not verified on a second display, and Intel Macs and the standalone Magic Trackpad are unverified. If free matters most and you are comfortable with those trade-offs, it is the best free starting point.

Limits: edges only, no support contract, and no per-app scenes.

5. HaptiTrack — the best free haptics + extra edge controls

HaptiTrack is a free open-source app for macOS 14 or later. It adds haptic feedback to scrolling, then uses the four edges for volume, brightness, keyboard backlight, microphone gain, and Night Shift. Each edge is configured separately, and the settings panel draws the trackpad to scale.

It requires both Accessibility and Input Monitoring, is not signed or notarized, and is a first release. It is the most interesting free app if you want haptics beyond a slider tick and do not mind an early build.

Limits: unsigned, early, no per-app scenes, and a more technical setup.

6. EdgeControl — the best experimental edge detection

EdgeControl is free and open source. Its idea is clever: the gesture must start from the laptop body and enter the trackpad at the extreme edge, not from the middle of the pad. That makes accidental triggers much less likely. It supports volume or brightness on either edge, haptics, a HUD, and experimental DDC for external displays.

It is explicitly experimental: validated on macOS 26.5 on Apple silicon, with Intel and external trackpads untested. It is not notarized. Try it if you enjoy testing a promising idea, not if you need a finished daily driver.

Limits: two edges, experimental, no per-app scenes.

7. EdgePad — the best free media scrub

EdgePad is free and open source under MIT for macOS 13 or later. It maps the top edge to media scrub, the left edge to volume, the right edge to brightness or vertical scroll, and the bottom edge to horizontal scroll. It uses native macOS HUDs, has a reading mode, and suppresses edge gestures shortly after typing.

It is ad-hoc signed and aimed at people who want media scrub on the edge without paying. It is not a per-app scene system.

Limits: ad-hoc signed, no per-app scenes, and the media scrub only works where the focused player responds to arrow-key seeks or supported media commands.

8. Sleight — the best alternate gesture language

Sleight is free and open source under GPL-3.0 for macOS 14 or later. It is not strictly an edge app: its signature is a two-finger dial for volume, a three-finger dial for brightness, and an edge slider for keyboard backlight. It also supports custom finger zones, taps, shortcuts, and scheduled automations.

If you want to try a different physical model — twisting two fingers like a knob instead of sliding an edge — it is the most creative app in the group. The trade-off is a learning curve and no per-app scene editor.

Limits: dial gestures take practice, no per-app scenes, and no commercial support.

9. TrackStudio — the best whole-surface option (not an edge-only app)

TrackStudio is the app we make. It includes edges, but it is not an edge-only app. The surface has left, right, and bottom edges, four corners, custom rectangular areas, and a center gesture area. Each app can have its own scene: brightness and volume rails, media scrub, tabs, navigation, undo/redo, window halves, screenshots, Mission Control, App Switcher, and other actions. Haptics are part of the interaction: detents on the rails, ticks for actions, texture while scrubbing.

It costs ₹499 one-time and runs on macOS 13 or later. There is no trial listed. It is not a scripting platform, a key remapper, or a full window manager. If you only want volume and brightness on the edges, it is more app than you need — buy Slidr, Haptiker, or Glisse instead.

Best for: people who want a visible, per-app surface with corners, areas, media scrub, and haptics, and who are willing to pay more than an edge-only app.

10. BetterTouchTool and Trill — if you want edges inside a bigger tool

BetterTouchTool can build edge gestures and much more: 600+ actions, scripting, key and mouse remapping, window snapping, Stream Deck, and per-app conditional groups. It costs $15 for two years of updates or $25 lifetime, with a 45-day trial and macOS 12 or later. It is not an edge-first app, and you will configure the edge yourself.

Trill is $29 one-time with a 24-hour trial, macOS 14 or later, and three Macs. It has ready-made gesture sets, edge slides for volume and brightness, haptics, a Hyper Key, and window snapping. It is a guided all-in-one, not a dedicated edge app.

When an edge-only app is enough

When you need a whole surface

You need a whole surface when the edge is only one part of the layout. That means corners for Mission Control or screenshots, custom areas for undo/redo or tabs, a center gesture for an app action, and a different layout for Figma, Final Cut Pro, VS Code, or Safari. TrackStudio, BetterTouchTool, and TouchBridge are the apps to compare for that job.

What to avoid

• Overlapping edges. Do not run two edge apps that both own the right edge. Pick one owner per edge.
• Ad-hoc signed apps with no support. Glisse, EdgePad, EdgeControl, and HaptiTrack are honest open-source projects, but they are not notarized and may reset permissions after updates.
• Private-framework fragility. Many of these apps read raw trackpad data through undocumented APIs. A macOS update can break them. Check the last release date before you rely on one.
• Trials that are too short to test. A three-day trial is enough to know if the gesture feels right, but not enough to judge long-term accidental triggers. Test during real work, not a demo.

How we picked

We checked each vendor’s public page on November 2, 2026 for price, trial, macOS requirement, and feature claims. We did not install every app for this version. Where a vendor does not publish a fact, we say “not stated.” Prices exclude taxes and regional variation. We make TrackStudio, and we deliberately placed it after the edge-only apps because this page is about the edge-only job.
