Fliq vs cron-job.org
cron-job.org is a beloved free service that pings a URL on a schedule — perfect for hobby keep-alives and simple checks. Fliq is a Postgres-native scheduler built for production HTTP jobs: configurable retries, crash recovery, and a full per-attempt history. If a missed or failed call actually matters, the difference shows.

When cron-job.org is the right call
You want a free, no-account-needed way to hit a URL every few minutes — uptime pings, cache warmers, hobby keep-alives. cron-job.org has done this reliably for years and costs nothing.
When Fliq fits better
The call matters: a failed webhook should retry with backoff, a worker crash shouldn't silently drop the job, and you need to see exactly what happened on every attempt. Fliq adds retries, a crash reaper, and queryable history — plus an MCP server so AI agents can schedule jobs.
