A healthchecks.io alternative built for indie SaaS
healthchecks.io popularized the simple "ping this URL or we'll alert you" pattern for cron jobs, and it's a solid tool for that. SilentWatch covers the same heartbeat use case, and adds the parts that matter most for a small SaaS running on Stripe, Supabase, and Vercel: business-event monitoring and a Stripe webhook relay, out of the box.
