System Requirements

The basic features of Stagetimer are free to use, including creating and running up to three timers and messages. Upgrading to a Pro or Premium subscription includes additional customization options and advanced features. See the Pricing page for details.

Web Version

Stagetimer is available online at stagetimer.io and can be used on any device with an internet connection and a modern browser.

Browser
  • Chrome 101 or higher
  • Firefox 100 or higher
  • Safari 15.5* or higher
  • Edge 101 or higher
  • ... or comparable browsers
* May work on older Safari versions, but that's so difficult to test, so we cannot vouch for it.
Hardware Sucessfully tested on a Raspberry Pi 2 Model B+ and Samsung Galaxy S7, should work on any hardware capable of running a modern browser. Likely works on older systems and browsers, but was not explicitly tested.

Desktop App

The desktop app includes all the same features as the web version, with the added convenience of being able to use it without an internet connection. Available for free download from the user dashboard. Pro and Premium subscriptions include one offline license key.

Operating System
  • Windows 10 or higher
  • macOS 11 Big Sur or higher
  • Ubuntu/Debian (.deb, x64 and arm64)

Network Requirements

Stagetimer is a cloud-based service that requires an internet connection to sync between devices.

Connection Any internet connection - WiFi, ethernet, or mobile data. Works reliably on event WiFi, conference networks, and mobile hotspots.
Bandwidth Extremely low - typically 2-3 MB for an entire show. Stagetimer transmits timing events (start/end timestamps), not continuous data, so you won't compete for bandwidth with other devices on the network.
Latency Updates sync across devices in under 150ms on typical connections. Higher latency networks still work - timers continue accurately because start/end times are synchronized, not continuous timing signals.
Connection Drops If connection drops, running timers continue counting locally. The viewer automatically reconnects and syncs new actions once connection is restored. A subtle status indicator appears during extended disconnections.

For offline use or restricted networks, see the Desktop App.
