View source on GitHubKratos
Kratos is a lightweight Go framework for building cloud-native microservices. It provides small, explicit APIs for transport, middleware, registry, configuration, logging, encoding, and code generation so applications can focus on business logic.
Features
- API-first development with Protobuf and generated HTTP/gRPC code.
- Unified transport layer for HTTP and gRPC.
- Composable middleware for recovery, logging, validation, tracing, metrics, auth, and more.
- Pluggable registry, configuration, and encoding components.
- Standard-library
log/slogbased logging with OpenTelemetry extensions in contrib packages. - Consistent metadata, errors, validation, OpenAPI, and code-generation workflows.
- A contrib ecosystem for optional integrations such as registries, config stores, middleware, encodings, and observability.
Installation
Requirements
- Go 1.25 or later
- protoc
- protoc-gen-go
Install the CLI
go install github.com/go-kratos/kratos/cmd/kratos/v3@latest
kratos upgrade
Create a Service
kratos new helloworld
cd helloworld
go mod tidy
kratos run
Visit http://localhost:8000/helloworld/kratos after the service starts.
For a fuller generated service flow:
kratos proto add api/helloworld/helloworld.proto
kratos proto client api/helloworld/helloworld.proto
kratos proto server api/helloworld/helloworld.proto -t internal/service
go generate ./...
kratos run
Usage Example
package main
import (
"github.com/go-kratos/kratos/v3"
"github.com/go-kratos/kratos/v3/transport/grpc"
"github.com/go-kratos/kratos/v3/transport/http"
)
func main() {
httpSrv := http.NewServer(http.Address(":8000"))
grpcSrv := grpc.NewServer(grpc.Address(":9000"))
app := kratos.New(
kratos.Name("helloworld"),
kratos.Version("v1.0.0"),
kratos.Server(httpSrv, grpcSrv),
)
if err := app.Run(); err != nil {
panic(err)
}
}
v3 Migration
Kratos v3 reduces core dependencies and makes previously implicit behavior explicit. Review the v2 to v3 migration guide before upgrading production services.
