Terms of use
Effective 19 August 2026
Pulse is free software for macOS (Apple silicon). By downloading or using it, you agree to these terms.
License
Pulse is licensed under the MIT License. Source is on GitHub. We do not sell a subscription and we do not require an account.
No warranty
Pulse is not a guarantee that your services are up. Checks can fail, the poller can stop, and notifications can be missed. Use it as an extra signal, not as the only one. To the extent the law allows, there is no warranty of merchantability, fitness, or non-infringement, and we are not liable for lost data, downtime, or other damages.
Your checks
You are responsible for the URLs you enter, the credentials you store in Keychain, and any load those checks put on your systems. Do not point Pulse at systems you are not allowed to probe.
Unsigned builds
Current downloads are not signed with an Apple Developer ID. macOS Gatekeeper may block a double-click. Drag Pulse.app to Applications, then run xattr -cr /Applications/Pulse.app in Terminal, then open Pulse. The first check that reads a Keychain item will ask Pulse to use the keychain — choose Always Allow.
The site
We may change these pages, change how builds are distributed, or stop publishing them. The GitHub repository is the source of truth for the code.
