Quick verdict
Keybreak has a free plan rather than a 14-day clock, and demonstrates each of its 37 stretches on video while leaving out movements you choose to avoid; Restier costs less, adds a one-off lifetime licence, a Linux build and meeting detection.

Price
The two price differently. Restier sells a one-device licence at €7.99 a year or €19.99 once, with 2- and 5-device tiers. Keybreak Plus is £1.99 a month or £19.99 a year and has no lifetime option; a licence can be active on up to 3 devices at a time, across Mac and Windows. source source
The bigger difference is what happens if you do not pay. Restier is a 14-day trial with no free tier. Keybreak has a free plan, with break reminders and 8 stretches. source source
Platforms and meetings
Restier runs on macOS 11+, Windows 10+ and Linux, and says it detects meetings to avoid interrupting calls and supports full-screen overlays across multiple monitors. Keybreak runs on macOS and Windows, and times breaks from your real keyboard and mouse activity within the hours you set rather than from your calendar. source source source
What a break contains
Restier describes its breaks as visual resets, breathing prompts and posture cues. Keybreak’s are 37 stretches, each filmed with a real person and the hold timed on screen, chosen around focus areas you set and leaving out movements you have excluded. source source
