Is Zveltio really free — including the extensions?
Yes. Zveltio and all official extensions are MIT-licensed and free forever. You can use them commercially without restrictions. Third-party extensions on the marketplace may have their own pricing set by the developer.
What does "self-hosted" mean in practice?
You run Zveltio on your own server — a €20/month VPS handles most workloads. There are no per-seat fees, no API call limits, and no data leaving your infrastructure. You pay only for the server you choose.
What is the marketplace then?
The marketplace ships 56 first-party extensions today — all free, all reviewed before publish. Third-party publishing is in controlled launch during beta (submissions go through a manual review queue) and opens broadly once we exit beta; community extensions may be free or paid depending on the author.
