About Tyk
Tyk is an API management platform with an open source gateway at its core. It also covers developer portals, analytics and governance for REST, GraphQL, gRPC and AI traffic.
What it does
The gateway handles rate limiting, authentication, governance and observability for APIs. The AI Gateway features route LLM requests and apply controls to MCP tool calls and agent traffic, such as per-tool rate limits and filtered tool discovery. Configuration can be managed as code with an operator, sync tooling and GitOps workflows.
Key features
- Rate limiting and authentication for APIs
- Support for REST, GraphQL, gRPC and Kafka
- Proxy and govern LLM and MCP traffic
- Configuration as code with GitOps
Who it's for
