Free API and Background Jobs Stack

An edge API with a SQL database, queued jobs, webhook ingestion and logs. Every layer below is a tracked free tier, with its published limits and the date we last checked them. The tightest limit in the stack is usually the one you hit first.

Cron Monitoring: Healthchecks.io

• Monitored cron jobs20

Catch: No SMS, WhatsApp or phone-call credits on Hobbyist. The $5/mo Supporter plan keeps the same 20 jobs; Business ($20/mo) raises it to 100 jobs with 50 SMS/WhatsApp and 20 phone-call credits. Using multiple accounts to dodge limits counts as abuse.

This is one example combination, not a recommendation or sponsorship. Swap any layer for an alternative in the same category; confirm limits at each vendor before you build.
