Evans is an expressive universal gRPC client written in Go, offering both an interactive REPL mode with powerful completion and a stateless CLI mode for scripting. It supports all four RPC types, gRPC-Web, and JSON-formatted output for UNIX-style pipelines.

Use cases

• manually inspect and explore a gRPC api interactively
• call grpc endpoints from the command line
• test grpc services with streaming rpcs
• script grpc requests in ci pipelines
• pipe grpc responses through jq
• try a grpc api without writing a client

When to choose

• you need an interactive REPL to explore an unfamiliar gRPC api
• you want scriptable, stateless gRPC calls that compose with unix tools
• you need to exercise streaming or gRPC-Web endpoints during development

When to avoid

• you need automated gRPC load or contract testing in CI rather than manual calls
• you prefer a GUI client like Postman or BloomRPC
• your api uses non-protobuf IDLs
