Why agencies switch

Predictable costs. Kaspar is €9 or €24 per month. Members cost nothing extra: unlimited on Pro, up to 5 per workspace on Starter. According to the vendor's website (as of October 2026), Better Stack bills per responder licence and add-on. That is flexible but harder to budget up front.
Broken link scans included. Kaspar Pro scans up to 25 sites with 2,000 pages each for broken links every day. Better Stack's pricing page does not list this.
Deliberately lean. Kaspar does uptime, cron jobs and links. If you don't need a log or incident platform, there is less to set up.
Operated and hosted in Germany, with a German interface.

When Better Stack is the better fit

You need on-call and incident management. Better Stack offers schedules, escalations, unlimited phone and SMS alerts, and Slack- and MS Teams-based incident management. Kaspar alerts by email, Slack and Telegram, without on-call schedules.
You want logs, metrics, traces and errors in the same platform. That is not Kaspar's focus.
You need checks from multiple locations, Playwright transaction checks or status pages. Kaspar checks from one location in Germany and has no status pages.
You want to start on a free plan. According to the vendor's website (as of October 2026), Better Stack includes 10 monitors and heartbeats for free.

Moving from Better Stack to Kaspar

List your uptime monitors and heartbeats, including interval and grace period.
Create them in Kaspar. Each heartbeat gets its own ping URL.
Replace the Better Stack heartbeat URL in your cron jobs and workers with the Kaspar URL.
Set up email, Slack or Telegram alerts. If you still need phone call alerts, keep your existing on-call tool for that.
Run both services in parallel until the alerts match.
