VecturaDB on one Compute Engine VM, with HTTPS and API keys, from an Open in Cloud Shell button and a guide with VecturaDB already chosen. The server and its data stay in your Google Cloud project, Google bills you directly, and the template is open source.
For a server in use every day.
Estimated Google Cloud cost
12.98 USD a month on your Google Cloud bill
e2-micro with its disks and external IP, whatever the use. The API key adds 0.06 USD a month beyond the 6 free secret versions of the billing account.
The template is free and open source (Apache 2.0). You pay only Google Cloud, which bills you directly: no fee from us.
Cost: an estimate with the Google Cloud list prices of europe-west1 in USD, on 4 November 2026, without the snapshots of the backups. The details are on the page of the template.
The button opens Cloud Shell, the terminal of your Google Cloud console, with the template and a guide on the side, with VecturaDB already chosen. Google asks to confirm the clone of the repository: without “Trust repo”, Cloud Shell is temporary, and the guide signs you in.
Choose the project, then run the commands of the guide: they install Terraform, keep its state in a bucket of your project, ask the IP address that may connect and the API key, and create everything. In our tests the server answered over HTTPS in 7 to 9 minutes.
The url output is the address of your server, over HTTPS. The Chroma clients connect to it with the API key.
