Supported stacks
Eight Nolay templates, Railpack and your own Dockerfile. Build time and image size are measured on a test VPS with 1 vCPU and 1 GB.
Free: 1 server, 1 project, 1 domain. You pay your hosting provider for the server.

Nolay templates
A Nolay template knows how to build and run the stack. Pick a stack to see what the agent will do. Your own Dockerfile works too.
- How the agent recognises the stack
- package.json with the next dependency
- Run
- node server.js from .next/standalone, port 3000, user node
- Build, cold and repeat
- 127 and 104 s
- Image
- 308 MB
Measured on a VPS with 1 vCPU and 955 MB on 22 September 2026.

Tested stacks
Measured on 22 September 2026. All eight Nolay templates pass without caveats, three combinations with the auto builder have caveats.

Questions about stacks
Three conditions: the project runs locally, you know how to start it, and its stack is in the table of tested stacks. If the stack is not there, your own Dockerfile works too.
template: a Nolay template for a known stack, no Dockerfile needed. auto: Railpack detects the stack itself, its images are larger. dockerfile: your Dockerfile from the repository. static: a ready static build. The builder is chosen in the project wizard and written to nolay.toml.
Railpack builds larger images than the templates. On the test VPS with an 8.6 GB disk, a repeat build of Bun and Next.js through Railpack fails for lack of space, and Django through Railpack does not start without an explicit builder. Through Nolay templates the same projects build and run without errors.
Run one installation command as root. The panel shows it with your server token already filled in. After that the server appears in the panel and everything else is done there.
