The IsDown alternative
Compare the products, then review the Pro plan if you need individual vendor alerts and early signals.
When ServiceAlert is a practical replacement
The Pro plan is the closest starting point when your main need is individual vendor alerts and early signals. Verify the following capabilities against the workflow you use today.
- Uptime monitoring for your own services: Yes
- Basic SSL monitoring: Yes
- Incident management: Full SEV1–SEV4 lifecycle + Slack war rooms
Reasons to keep IsDown
If you only need third-party status aggregation for a small team and Chrome-extension visibility matters most, IsDown is a focused product. ServiceAlert is the broader reliability workflow for vendor status, first-party uptime, status pages, incidents, and basic SSL monitoring.
Plan a parallel replacement
Run both products in parallel until ServiceAlert has reproduced the signals your team actually uses. There is no automated-import promise, and you do not need to cancel first.
- InventoryChoose the three vendor dependencies or owned endpoints that drive the most incidents.
- RecreateAdd those signals in ServiceAlert while keeping IsDown active.
- CompareValidate alert timing, routing, status-page behavior, and retained evidence side by side.
- Cut overMove the remaining workflow only after owners agree the parallel run is complete.
