He found the incumbents overpriced, so he open-sourced a cheaper cron monitor. 9 years on, it's his full-time salary.

Will it work? · our read
Fairness compounds. A solo, open-source cron monitor paying a full-time salary. Radical fairness and 9 years of trust beat a fancier feature set. Small by design, and hard to dislodge.
01How the money moves
A team's nightly backup cron dies silently — nobody notices for days
They wire a 2-line HTTP ping into the job; Healthchecks learns its schedule
Ping goes missing -> instant alert. Teams pay $20-80/mo for that safety net

Revenue is first-party: $14,043 MRR and 652 payers come from Caune's own July 2024 blog post (verified, STATED). Latka estimates a lower about $111.5K ARR; we trust his disclosed figure. Origin ('the existing services were overpriced') is his documented quote. Drama is mild — this won on patience, trust, and fair pricing, not a single dramatic move; the open-source bet is real and documented. We never score you.
