- Free service
Thanks to Exoscale, which has kindly offered two servers, we can provide Kroki as a free service!
However, some parts of the infrastructure are still host on other providers, so we are still looking for sponsors to cover all the expenses.
If you are interested, please 👋 contact us.
The public instance of Kroki does not do any remote call for performance and security reasons. We also want to keep the API as simple as possible, so it takes a text diagram as input and returns an image.
