Percentages lie.

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

Grouped by error class, file, and line.

Alerts that learn your baseline

New errors, regressions, spikes.

Uptime monitoring

Pings your app every minute. Alerts when it's down. Just paste a URL.

Data retention

Keep logs for a week, a year, or forever. Your call.

Questions

What do I get for $99?
Everything. Logs, errors, alerts, uptime checks, AI debugging, all SDKs. One price. No subscriptions. 30-day money-back guarantee.
Does it monitor uptime?
Yes. Paste your app URL when you create the app and LogNorth pings it every minute. 3 consecutive failures = down.
Why not use Sentry?
Sentry is a platform. LogNorth is a single Docker container. One file database. No dependencies. Runs on a $5 VPS. That's the trade-off: fewer features, zero complexity.
What frameworks are supported?
Go, Node/Bun, and Rails. Also accepts OpenTelemetry logs (OTLP/HTTP). 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, Telegram, or email with your own SMTP.
How long are logs stored?
You decide. Default is 90 days. Configure from 7 days to 1 year, or keep them forever. Shorter retention = smaller database.
Do I get updates?
Yes. Run lognorth update on your server and you're on the latest version. All updates within the current major version are included.
