Say hello ↗Good questions.
How do I get access?
Join the early access list and tell us a little about your project. We invite teams directly and help you choose the right starting point.
Can I keep my existing tools?
Use the S3-compatible API with your existing integrations, or the SIS3 CLI for everyday storage work. Start with the migration and developer guides.
Where does my data live?
On servers in Slovenia. For procurement, data processing terms or resilience requirements, contact us to discuss your workload and contractual needs.
What happens if I need more space?
The included storage is an allowance, not a hard cap. Extra storage is €0.85–€1.00 per GB-month and extra outbound transfer is €0.01 per GB, excluding VAT. You can also move to a larger size.
