| Customization | Its metadata model lets an instance configure dependencies and supported JVM and platform versions. | Users can replace Mustache templates with their own directory and create custom generator modules using the meta command. |
| Purpose | Spring Initializr provides an extensible API to generate JVM-based projects. | Swagger Codegen generates API client libraries, server stubs, and documentation from OpenAPI specifications. |
| Self-hosting | The documentation says you can create your own Initializr service by using its jars as libraries in your application. | The generator service can be deployed locally through a Docker image named swaggerapi/swagger-generator-v3. |

Swagger Codegen
Swagger Codegen is an open-source tool that generates API client libraries, server stubs and documentation from OpenAPI specifications. Its template-driven engine parses OpenAPI or Swagger definitions and produces project code from schemas. Swagger states that it can generate client SDKs in over 40 languages and server boilerplate in over 20. Listed capabilities include OpenAPI import, schema-to-code generation, project scaffolding, custom templates, an interactive API reference, code samples and a command-line interface. Outputs and integrations include HTML and Confluence Wiki documentation, Apache2 configuration files and JMeter. The project is available from GitHub under the Apache-2.0 license, with a hosted option through SwaggerHub. SwaggerHub can generate code in a selected language and push it to source-control repositories. Supported client targets include C#, Dart, Go, Java, JavaScript, Kotlin, PHP, Python, R, Ruby, Scala, Swift and TypeScript variants. Server targets include ASP.NET Core, Go, Java Vert.x and JAX-RS options. The repository warns that untrusted descriptions may cause code injection.
