Gatus vs Instatus
Both are alternatives to Atlassian Statuspage. Here's how they stack up — verified facts, no spin.
Also searched as Instatus vs Gatus — same comparison, one verdict.
Gatus
Monitoring as a YAML file, for people who already run everything from Git.
Gatus is a developer-first health-check service configured entirely in YAML, which means your monitoring lives in the repository, gets reviewed in pull requests, and is deployed like any other code. It handles HTTP, TCP, ICMP, DNS and TLS-expiry checks, evaluates rich conditions on responses — status code, body content, response time, certificate age — and ships a clean dashboard and status page. Apache-2.0, around 11.7k stars, actively developed. It is the natural pick for a team already doing GitOps, and the wrong one if a non-engineer needs to add a monitor.
Instatus
A fast, cheap status page that does the one job well.
Instatus is a focused competitor to Statuspage: fast pages, unlimited subscribers on paid plans rather than metered ones, custom domains, and a free tier that is genuinely usable. It is proprietary and hosted, and it is here because subscriber-metered pricing is the specific complaint that sends people looking, and Instatus's answer to it is to not meter subscribers. For a team that wants a customer-facing status page and does not want to self-host one, it is usually the cheaper straight swap.

Gatus edges it on the Sovereignty Score, but the right pick depends on the trade-offs below.
Gatus
Strengths
- +Configuration is YAML in Git — reviewed, versioned and diffable
- +Rich condition evaluation, including response body and TLS expiry
- +Apache-2.0 with no enterprise carve-out
- +Very light: one small binary, minimal memory
Trade-offs
- −No UI for adding monitors — everything is a config change
- −Same blind spot as any self-hosted monitor: it can go down with you
- −Fewer notification integrations than Uptime Kuma
- −Not usable by non-technical team members
Instatus
Strengths
- +Does not meter subscribers, which is Statuspage's sharpest cost edge
- +Very fast pages and a clean, modern design
- +Custom domains available on low tiers
- +Straight swap — migration is mostly re-entering components
Trade-offs
- −Proprietary and hosted; no self-host path
- −Smaller company than Atlassian, which matters to some procurement teams
- −Fewer integrations than Statuspage
- −Still a second tool if you already run Uptime Kuma
