Your data, your exports
Everything you export is yours to keep, even after you cancel.
Founding price for life
Early subscribers keep $6/mo or $60/yr as long as they stay subscribed.
Who Pro is for
- Engineering leads who own an observability budget and don’t want surprises at renewal.
- Founders on free tiers who need to know the day a limit shrinks.
- Procurement / FinOps people who need dated evidence of price changes.
Honest fine print
- Alerts come from the same automated page checks plus a human review, so “same day” means within about a day of detection, not real-time.
- We don’t invent data: exports contain exactly what the site shows, plus history.
- The site, API and weekly email stay free. Pro pays for the time to keep them accurate.
