Better Stack vs Checkly: uptime vs synthetic monitoring
Better Stack and Checkly both watch whether your app is reachable. Better Stack leans into incident response, heartbeats and a broader observability suite. Checkly leans into developer-owned synthetic checks (Playwright + API) as code. Prices below are from each product's public pricing page as of October 2026.
Quick pick
- Choose Better Stack for HTTP/uptime + cron heartbeats, phone/SMS on-call, status pages, and the option to add logs/errors in the same product — the path we document in our uptime guide.
- Choose Checkly when you need rich Playwright user-journey checks, API multistep flows, and monitoring checked into git via CLI/Terraform/Pulumi.

Checkly: Detect / Communicate / Resolve modules are priced separately. Detect Hobby $0; Starter $29/mo or $24/mo annual; Team $80/mo or $64/mo annual — see checklyhq.com/pricing. Confirm module add-ons if you need status pages or AI RCA.
How this maps to FixStack
Simple "is /api/health returning 200?" monitors and cron heartbeats are enough for most FixStack errors. Reach for Checkly (or Better Stack Playwright minutes) when an HTTP 200 still ships a blank page or a broken checkout — the failure only shows up in a real browser path (see blank page after deploy).
