Golem Cloud
Golem is open source and free forever (BUSL-1.1, transitioning to Apache-2.0). Golem Cloud is the operations stack we built around it — we host it for you, or you host it yourself.
Which path is right for you?
Golem Cloud
Developer Preview today (free, no guarantees). Paid tiers with full SLAs and 90-day retention coming soon.
Get started →Golem Cloud On-Prem
Same software, you host it. Annual license. Runs on AWS, GCP, Azure, or on-premises. Available now.
Talk to sales →We host Golem for you.
Pricing is tentative — final numbers at launch. Unlike providers that host you on someone else's compute, your code runs on our infrastructure. The free tier is small for that reason.

On the paid Standard tier, oplog history is retained for up to 90 days, configurable per workspace. Retained oplog is compressed and stored to S3 — your storage line covers both active and archival.
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, oplog inspection, deployment lifecycle
- Coming soon: agent rebalancing and scheduling optimisations
The OSS edition is the runtime. Golem Cloud is the operations stack we built around it. On-Prem is the same operations stack, 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 paid tiers launch?
- Coming soon — sign up for the waitlist and we'll notify you.
- Why is the free tier on paid Cloud going to be small?
- 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.
- What happens if I exceed my plan?
- Overage fees on agent-seconds, RAM, and storage. Serious workloads should move to Custom.
- What's the retention policy?
- 90 days configurable on managed Cloud (Standard tier). Custom is unlimited. We compress and store retained oplog to S3 under your storage line.
- Why does Golem charge for storage when other runtimes don't?
- Golem's durability depends on a persistent oplog of every effect. The oplog is the recovery mechanism — so we charge for the storage that makes byte-identical replay possible. Retention is configurable for that reason.
- 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.
