Never miss the next bright pass
Choose a satellite and a place. You get a calendar file with one event per pass you can actually see (sunlit satellite, dark sky) and a reminder ten minutes before it comes into view. It works in any calendar, with no account, even with this page closed.
Your reminders
For integrations: webhooks
Planned, not available"Call my endpoint twenty minutes before the next pass" is on the roadmap for API customers: a ground station that should wake up, a bot that should post. It will be built when someone needs it. Until then, the API gives every pass of the next ten days in one call, which a scheduled job can turn into its own alerts.
