Looking for a Healthchecks.io alternative?

Healthchecks.io deserves a lot of respect. It's open source (BSD license), self-hostable, and has been running reliably since 2015. Peteris Caune built it as a solo project, and it's grown into one of the most-referenced tools in the cron monitoring space. If you want full control and are comfortable running your own infrastructure, Healthchecks.io is an excellent choice.

CronSafe is a managed alternative. You don't host anything, and you get a different set of trade-offs: a more modern dashboard, built-in Discord and Telegram alerts without extra configuration, and zero maintenance overhead. Here's how they compare.

CronSafe vs Healthchecks.io — feature comparison

When to choose Healthchecks.io

Healthchecks.io is the better choice if:

• You want to self-host and own your monitoring data entirely
• You value open source and want to audit or modify the code
• You need cron expression parsing — Healthchecks.io understands crontab syntax and can calculate expected run times automatically
• You need more than 5 free monitors — Healthchecks.io offers 20 on the hosted free tier, or unlimited if you self-host
• You're already running the infrastructure to host it (Docker, PostgreSQL, a server)

When to choose CronSafe

CronSafe is the better choice if:

• You want zero infrastructure to manage — no Docker, no database, no updates
• You need Discord alerts built-in without configuring custom integrations
• You prefer a modern, minimal UI focused on one task
• You want to be set up in 30 seconds flat: sign up, create monitor, add curl, done
• You're a solo developer or small team that doesn't want to maintain monitoring infrastructure

Migration from Healthchecks.io

Both services use the same heartbeat model, so migrating is a URL swap:

# Before (Healthchecks.io)
0 2 * * * /usr/local/bin/backup.sh && curl -s https://hc-ping.com/your-uuid-here

# After (CronSafe)
0 2 * * * /usr/local/bin/backup.sh && curl -s https://api.getcronsafe.com/ping/abc123

One line per job. Create the corresponding monitors in CronSafe with the same interval and grace period, swap the URLs, and you're done.

A note on open source

CronSafe is not open source. If owning and auditing the source code matters to your team, Healthchecks.io is the right tool. There's no shame in that — it's a genuinely great project that Peteris has maintained with care for years. CronSafe exists for developers who want a managed service with no setup overhead, not as a replacement for the self-hosted model.
