How to choose

What will it cost to get started?

Check whether the tool has a free plan, a trial, or a paid starting price. Pricing may be per user or per month, and some providers give pricing on request.

For example, AlertOps lists a free plan, a 14-day trial, and paid plans from $10 per user per month. Alerta is listed as free and open source.

Which platforms does it need to run on?

Check the platform marks against where your team needs to use the tool. The board covers web, API, Android, iOS, Linux, and macOS.

Alerta lists API, Linux, self-hosted, and web support; Everbridge IT Alerting lists Android, iOS, and web.

How should the team handle an alert?

Compare on-call scheduling, escalation policies, and alert acknowledgment. These features relate to assigning coverage, moving an alert to another responder, and recording that someone has seen it.

Check the listing details for the response features your team needs.

Will it connect to our alert sources?

Review the alert-source integrations and public API marks when checking how a tool can connect with your existing systems. An API is a way for software to exchange information with other software.

Do we need mobile alerts or a status page?

Check mobile app support if responders need to receive or acknowledge alerts away from a computer. Compare incident status pages if you need a way to share incident status.

The board includes mobile apps and incident status pages as comparison points.
