How to Switch from Cronitor
Migration takes less than 15 minutes. Here's your step-by-step guide.
Export your sites from Cronitor
Pull your monitor list out of Cronitor — most tools offer a CSV export, or you can copy the URLs straight from the dashboard.
Create your free Lemwatch account
Sign up for the free tier — 10 sites, all check types, no credit card. Run it alongside Cronitor while you compare.
Import and map your monitors
Paste or bulk-upload the URLs you exported from Cronitor. Lemwatch auto-detects the platform, SSL state and sitemap for each one.
Rebuild your Cronitor alert routing
Point alerts at the same channels you use today — email, Slack, Discord, Teams, PagerDuty or webhook — then set thresholds to match your Cronitor config.
Run both in parallel, then cancel Cronitor
Give it one billing cycle. Once Lemwatch alerts match Cronitor's on the same incidents, cancel and keep the history in Lemwatch.
