Run Golem Cloud inside your own cloud.
Golem Cloud On-Prem is the identical software we run for managed customers — only you run it yourself, in your own Kubernetes cluster, on any cloud or on-premises. Licensed annually.
What's included
- Golem Kubernetes Operator — deploy, scale, and roll out Golem clusters declaratively
- Prebuilt OpenTelemetry exporters + dashboards — the observability stack we run in production
- Operational tooling — health monitoring, audit log inspection, deployment lifecycle
- Coming soon: controls for how agents are distributed and when they run
The OSS edition is the runtime. Cloud is the version we run for you. On-Prem is the same software, packaged for your cloud.
Who it's for: teams large enough to want Golem inside their own cloud — whether that's because of regulation, sovereignty, or because your existing infrastructure runs on GCP or Azure and you want Golem to run there alongside it.

Frequently asked questions
- Is Golem Cloud available today?
- Yes — Golem Cloud is currently in Developer Preview: free to use, with no SLAs or data-retention guarantees. Paid tiers with full guarantees are coming soon.
- What can I do during the Developer Preview?
- Evaluate, experiment, prototype. The Preview is not intended for production workloads.
- When will the Paid tier launch?
- Coming soon — sign up for the waitlist and we'll notify you.
- How is compute measured?
- In Golem Compute Units (GCU). One GCU represents a fixed amount of WebAssembly execution work. Because the unit is deterministic, the same workload produces the same GCU on any machine.
- Do idle or suspended agents cost me money?
- No. Memory is billed only while your agent's code is actively executing. Durable-storage metering stops when we shelve an inactive agent; ephemeral storage stops at the end of each invocation. No traffic, no bill.
- What happens if I hit a limit?
- Concurrent-agent and app/environment caps reject the request at allocation time. Compute, memory, and storage are usage-metered without hard caps; raise the per-agent ceilings by contacting support if your workload outgrows the default.
- Why is the free tier capped at 1,000 GCU/month?
- Because compute runs on our infrastructure, unlike providers that host you on someone else's compute. The runtime is free; what you pay for is what we run for you.
- Why does Golem charge for storage when other runtimes don't?
- Golem's durability depends on a complete history of every action — that's how it recovers when a node fails. We charge for the storage that makes that history possible.
- Will invoices come in my local currency?
- At launch, USD, GBP, and EUR are planned. Other currencies on request.
- What's in Golem Cloud On-Prem that's NOT in the open source edition?
- Kubernetes Operator, OpenTelemetry exporters, prebuilt dashboards, operational tooling — the same package we use to run Golem Cloud ourselves.
- Can I run Golem in my own cloud without buying the On-Prem license?
- Yes — the OSS runtime is full-featured. You'd be responsible for your own deployment, monitoring, and operational tooling.
- Who provides support for the open source edition?
- Ziverge, our exclusive partner for commercial OSS support.
