Best alternatives to Upright in 2026
Most uptime monitors are a paid subscription to someone else's cloud, watching your site from servers you don't control. Upright flips that: it's a piece of software you run yourself, on cheap servers you pick, that pokes at your websites and services on a schedule and screams (via alerts) when something's wrong. Upright is the open-source synthetic monitoring system that Basecamp built to watch over Basecamp, HEY, Fizzy, and their other products. It's a Rails engine you deploy to inexpensive VPS nodes around the world using Kamal, running health-check probes — real browser checks via Playwright (which can log in, click through a flow, and verify it actually works end-to-end, capturing video on failure), plain HTTP checks, SMTP handshake tests, and traceroute latency analysis. Everything reports back as Prometheus metrics and OpenTelemetry/OTLP data, so it plugs into AlertManager for paging and Grafana for dashboards, with OmniAuth login for any OIDC provider.
