grpcurl is a command-line tool that lets you interact with gRPC servers. It's
basically curl for gRPC servers.
The main purpose for this tool is to invoke RPC methods on a gRPC server from
the command-line. gRPC servers use a binary encoding on the wire (protocol
buffers, or "protobufs" for short). So they are basically impossible to interact
with using regular curl (and older versions of curl that do not support HTTP/2
are of course non-starters). This program accepts messages using JSON encoding,
which is much more friendly for both humans and scripts.
With this tool you can also browse the schema for gRPC services, either by
querying a server that supports server reflection, by reading proto source
files, or by loading in compiled "protoset" files (files that contain encoded
file descriptor protos). In fact, the way the tool transforms JSON request data
into a binary encoded protobuf is using that very same schema. So, if the server
you interact with does not support reflection, you will either need the proto
source files that define the service or need protoset files that grpcurl can
use.

Frequently asked questions
Is gRPCurl free?
Yes. gRPCurl is open-source software under the MIT licence.
Is gRPCurl safe to download?
The download comes from github.com, which belongs to the publisher; ExeAtlas does not host or change the file. Compare its SHA256 hash with the one shown here, or open the VirusTotal report for that hash.
How do I install gRPCurl with winget?
Open PowerShell or Windows Terminal and run the winget command shown on this page. winget downloads the official installer and checks its SHA256 hash before running it.
Does gRPCurl run on ARM (Windows on Arm)?
There is no ARM64 build; Windows 11 on Arm can run the 64-bit and 32-bit version through emulation.
Can I use gRPCurl without administrator rights?
Yes, it is portable: unpack and run it.
What are alternatives to gRPCurl?
Go Programming Language, LLVM, Deno, CMake and Yarn. The alternatives page compares them.
