Where it sits in the data

Healthchecks.io's $14K a month is higher than 71% of the 6,604 projects with founder-reported monthly revenue in our dataset; the median across them is $2K. Snapshot: 2026-09-30. The dataset only covers founders who chose to publish their numbers, so it leans toward businesses that work; use it for scale, not as an average.

Currency

All figures are in US dollars as published. A rough yuan or euro conversion is not applied here because prices, taxes and acquisition costs differ by country.

Could you build something like this?

My view is that demand comes from developers and teams that need to know when scheduled work stops checking in. The buyer is a technical team or an individual developer responsible for cron jobs, background workers, and scheduled tasks. Distribution would have to come from developer communities, open-source channels, documentation, and integrations.

Building the core product is possible, but reliable alerting, integrations, self-hosting, and support create real work. Alert delivery, incident-management integrations, account security, and uptime expectations also add operational responsibility. In my view, this needs sustained technical and support effort.

Verdict: Needs real work.

One thing to take from it

My view is that a focused monitoring service can combine a free entry plan with paid tiers for larger job volumes and support. Healthchecks.io also gives developers visible proof through open-source code, self-hosting, integrations, and public status badges.
