Sovereign observability · On-prem or your own cloud
Metrics, traces and logs on infrastructure you own. An SRE agent that finds the root cause while you sleep. And a bill you can predict to the dollar — no per-gigabyte surprises.
Built on open standards · Trusted where data can't leave the building
The platform
A full observability suite you run yourself — no data shipped to a vendor, no sampling to save on your bill.
Observability suite
Correlated metrics, distributed traces and logs, with dashboards and alerting out of the box. OpenTelemetry-native, so your instrumentation is never locked in.
Why did checkout p99 spike at 14:00?
It correlates to a DB pool exhaustion on checkout-svc. Deploy #4821 halved the pool size 12 min earlier. I drafted a rollback and a PgBouncer config. Review →
The SRE Agent
Ask it in plain language, or let it watch. It reads traces, metrics and logs, finds the root cause, and drafts the fix — grounded in your real data, running inside your own perimeter.
Predictable costs
Per-gigabyte observability pricing punishes you exactly when you need visibility most — during an incident. ByLonis is flat and predictable: you size it, you own it, you know the number.
Monthly observability bill · 3 TB/day
Illustrative. Your real number is fixed the day you size the cluster.
Where your telemetry lives
Nothing is shipped to a third-party vendor. Ever.
Sovereign & on-prem
For teams that can't send logs to someone else's cloud — finance, health, public sector, or anyone under a data-residency rule. ByLonis runs where your data already is.
Ready when you are
See ByLonis on your own stack. We'll help you size it, stand it up, and point the SRE agent at your first incident.
