TChannel is a network multiplexing and framing protocol for general-purpose RPC, with peer libraries in Node.js, Python, Go, and Java. It supports out-of-order responses, request fragmentation, optional checksums, and transporting multiple protocols such as HTTP+JSON and Thrift.

Use cases

• build high-performance RPC between microservices
• multiplex many requests over a single connection
• forward requests quickly through intermediaries
• transport Thrift and HTTP+JSON over one protocol
• fragment large requests and responses progressively
• inspect TChannel traffic with packet capture tools

When to choose

• you maintain an existing Uber-style microservice stack already speaking TChannel
• you need out-of-order request/response multiplexing over TCP
• you need a simple multi-language framing protocol to implement yourself

When to avoid

• starting a new project, since the project is no longer active
• you need a maintained protocol with ongoing security fixes
• you want standard RPC ecosystems like gRPC with broad tooling
