Calmping vs UptimeRobot
UptimeRobot is a mature, popular monitor with broad check coverage and an unusually generous free tier. If you want the widest set of simple checks for free, it's hard to beat. Calmping's difference is what happens after a check fails — it confirms the failure, opens an incident with the evidence attached, drafts the postmortem, and remembers the fix — plus database-aware checks, AI diagnosis, an open MCP server any AI agent can query (Claude, Cursor, Codex, or your own), a privacy-first status page, and the option to self-host.

Which should you pick?
Choose UptimeRobot if…
You want the most free monitors (its free tier is generous), broad simple checks, and a public status page — and you don't need database-aware checks, postmortems, or self-hosting.
Choose Calmping if…
You monitor databases, want auto-postmortems and memory after an incident, care about data privacy or self-hosting, or want AI-assisted diagnosis when something breaks.
