# ai-serving vs Server

*GraphCanon updated Sep 20, 2026*

## Verdict

Pick ai-serving if ai-Serving is an inference server supporting PMML and ONNX formats via HTTP or gRPC endpoints, easily deployable with Docker; pick Server if server is a standalone HTTP-based inference server for deploying Rubix ML estimators using PHP.

[ai-serving](https://github.com/autodeployai/ai-serving) reports 166 GitHub stars, 31 forks, and 3 open issues, last pushed Feb 24, 2026. [Server](https://rubixml.github.io/ML) has 63 stars, 13 forks, and 1 open issues, last pushed Mar 3, 2026. Figures are from public GitHub metadata via [ai-serving's repository](https://github.com/autodeployai/ai-serving) and [Server's repository](https://github.com/RubixML/Server).

## Decision facts: ai-serving

- **Adopt for:** Ai-Serving is an inference server supporting PMML and ONNX formats via HTTP or gRPC endpoints, easily deployable with Docker.

## Decision facts: Server

- **Adopt for:** Server is a standalone HTTP-based inference server for deploying Rubix ML estimators using PHP.

## Choose when

### Choose ai-serving if…

- ai-serving is primarily Scala; Server is PHP.
- License: ai-serving is Apache-2.0, Server is MIT.
- Tags unique to ai-serving: ai-serving, grpc, inference-server, onnx.
- When you need to serve models in both PMML and ONNX formats without manual configuration changes between formats.

### Choose Server if…

- Server is primarily PHP; ai-serving is Scala.
- License: Server is MIT, ai-serving is Apache-2.0.
- Tags unique to Server: api, http-server, inference-engine, infrastructure.
- When you are working with machine learning models trained in the Rubix ML framework and need to deploy them via a PHP-based infrastructure.

## When NOT to use ai-serving

- Avoid if your team lacks familiarity or willingness to use Scala for deployment through sbt build system for customization needs.
- Not suitable when only one model format, either PMML or ONNX but not both, is needed and a simpler solution would suffice.
- If your project strictly requires a non-Dockerized setup that does not align with using pre-built Docker images.

## When NOT to use Server

- Avoid using if your primary technology stack is not based on PHP, as it would necessitate integration with a non-native language environment, increasing complexity.
- Do not use this tool for large-scale deployments requiring high throughput and low latency typical of more robust languages like Python or Rust.
