Built and hosted on our own Kubernetes infrastructure.

Inside our own infrastructure

Context

When we say we host and operate the systems we build, this is what that means in practice. Our own infrastructure is the reference implementation for everything we deliver.

Problem

A young company promising "enterprise-grade, hosted, monitored" has to actually have that — not aspire to it. Credibility here isn't a claim, it's an architecture you can describe.

Solution

We run a highly-available k3s cluster on Hetzner:

  • PostgreSQL via CloudNativePG, with replication and automated failover.
  • RabbitMQ as a quorum-queue cluster for reliable messaging.
  • Redis with Sentinel for high availability.
  • Prometheus + Loki so nothing runs unobserved — logs and metrics feed alerts that reach us before most users notice.

Delivery timeline

This is ongoing work, hardened continuously as we learn from operating it.

Ongoing operations

The same monitoring, backups and update discipline we sell to clients, we run on ourselves first. If it isn't good enough for our own products, it isn't good enough to put a client on.

Outcome

Every client system inherits this foundation. The engineering write-ups on our blog document how it's built — proof, not adjectives.

Describe the pain. We'll bring a working system.

A short discovery call is enough for us to tell you what we'd build, how long it takes, and what it costs.
