How to Switch from SigNoz
Migration takes less than 15 minutes. Here's your step-by-step guide.
Export your sites from SigNoz
Pull your monitor list out of SigNoz — 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 SigNoz while you compare.
Import and map your monitors
Paste or bulk-upload the URLs you exported from SigNoz. Lemwatch auto-detects the platform, SSL state and sitemap for each one.
Rebuild your SigNoz alert routing
Point alerts at the same channels you use today — email, Slack, Discord, Teams, PagerDuty or webhook — then set thresholds to match your SigNoz config.
Run both in parallel, then cancel SigNoz
Give it one billing cycle. Once Lemwatch alerts match SigNoz's on the same incidents, cancel and keep the history in Lemwatch.
