The Insight

Percentages lie.

Most tools alert when errors exceed 5%. That number means nothing without context.

500 errors = 5%

Fire.

We learn your baseline. Alert when it's actually wrong.

I got tired of paying monthly for logs.
So I built this. Now you can use it too.

FAQ

Questions

What do I get during beta?
Everything, free. $100 one-time at launch. No subscriptions. 30-day money-back guarantee.
Why not use Sentry + a logging tool?
Because they're the same thing. An error is just a log with a stack trace. LogNorth treats everything as events—log() for normal events, error() for exceptions. Errors get grouped into issues, you get alerted. One tool instead of two.
What frameworks are supported?
Go, Node/Bun, and Rails. Also accepts OpenTelemetry logs (OTLP JSON). We take what matters and discard the rest. No traces, no metrics, no complexity.
How does alerting work?
LogNorth groups errors into issues, learns your baseline traffic, and only alerts when something needs attention. 1 error in 1,000 requests? Normal. Sudden spike? That's a real problem. Push notifications via ntfy.sh or email with your own SMTP.
How long are logs stored?
You decide. Default is 90 days (3 months). Configure anywhere from 7 days to 1 year in Settings. Shorter retention = smaller database. Old events are automatically deleted.
Can I skip health check routes?
Yes. SDKs let you ignore routes like /healthz or /_health. They won't be sent to LogNorth. See the SDK docs for configuration.
