FAQ

Questions?
We have answers.

Is NotifyBell free to try?
Yes โ€” NotifyBell is in early access and every feature is free to use with no credit card required. Paid plans are coming soon for teams who want dedicated support, SLAs, and advanced features. Early-access users will get preferential pricing when that happens.
How is this different from PagerDuty?
NotifyBell has the same core features โ€” escalation, on-call, priority alerts, integrations โ€” plus unique capabilities like 7-tier priorities with custom sounds, full-screen emergency takeover, built-in task management, and status pages and heartbeat monitoring included (PagerDuty sells these as separate add-ons for $89-699/month). And you can try everything free.
Can I migrate from Opsgenie?
Yes. We provide an Opsgenie migration tool that imports teams, escalation policies, and on-call schedules from Opsgenie's JSON export. With Opsgenie's shutdown in April 2027, now is the time to move. The migration takes about 10 minutes per team.
What systems does it integrate with?
Any system that can make an HTTP request. Pre-built connectors for Home Assistant, Proxmox, and SpamHalt. The generic webhook endpoint accepts any JSON payload. Prometheus, Grafana, Datadog, GitHub, GitLab, AWS CloudWatch, Zapier, and n8n all work through standard webhooks.
Do you have an iOS app?
Android app is available via Google Play Store and direct APK download. iOS app is on the roadmap. The web dashboard works on iOS Safari in the meantime.
Is it secure enough for enterprise?
Yes. Microsoft SSO, TOTP 2FA, full audit logging, per-API-key rate limiting, TLS 1.2+ encrypted transport, encrypted secrets storage. Self-hosted means your data never leaves your infrastructure. SOC2 and HIPAA compliance is achievable through your own deployment controls.
How fast are critical alerts?
Sub-second WebSocket delivery to logged-in devices. FCM push typically 2-5 seconds end-to-end. Voice calls within 10-15 seconds. Full emergency sequence (push โ†’ phone alarm โ†’ siren โ†’ escalation) completes within 30 seconds.
Can I white-label it?
Yes. Self-hosted deployment gives you full control over branding, logo, colors, domain, and content. Contact us for enterprise white-label support.
