For a server in use every day.
Estimated AWS cost
12.48 USD a month on your AWS bill
t4g.micro with its volumes and public IPv4, whatever the use.
The template is free and open source (Apache 2.0). You pay only AWS, which bills you directly: no fee from us.
Times: medians in our tests, against the server on the instance itself. Cost: an estimate with the AWS list prices of eu-west-1 in USD, on 29 October 2026, without the snapshots of the backups. The details are on the page of the template.
Launch Stack opens the quick-create page of CloudFormation in eu-west-1, in your AWS account. You choose the server, the instance type, the access and the IP addresses that may connect.
Tick the three acknowledgements and create the stack. The stack is complete when the server answers over HTTPS.
Open the Outputs tab: Url is the address of your server, over HTTPS. The Chroma clients connect to it.
