AI-generated from listing dataone-api offers a free, single‑binary solution for unifying LLM providers, while kong provides a richer, enterprise‑grade API gateway with broader protocol support but at a cost and higher complexity.
Key differences
- •one-api focuses solely on LLM API unification and key management; kong is a general‑purpose API/AI gateway with microservice routing and security features.
- •one-api is free and open‑source with minimal support; kong uses a freemium model with email/documentation support and more extensive enterprise resources.
- •Deployment complexity: one-api is a single executable/Docker image; kong requires Docker/Kubernetes integration and more infrastructure.
- •Customization: one-api offers limited plugins; kong has an extensive plugin ecosystem for custom behavior.
- •Supported protocols: one-api only handles OpenAI‑compatible HTTP calls; kong supports HTTP, gRPC, WebSockets and MCP traffic.

Common questions
Is there any cost to use either product?
one-api is free; kong offers a freemium tier that may require payment for advanced features.
Can I run the solution with just a single Docker command?
Yes for one-api (single binary/Docker image); kong requires additional setup with Docker/Kubernetes and configuration.
Do both tools support Chinese LLM providers?
one-api explicitly supports Chinese providers (ChatGLM, ERNIE, Spark, Qwen, Hunyuan); kong’s provider support is not specified.
