  3. keploy

    Unit, API & Integration Testing Agent for Developers. Generate tests, mocks/stubs for your APIs that actually work!

    Project mention: API Testing Without the Hassle – My Experience Using Keploy for CI Integration | dev.to | 2025-07-06

    Recently, while working on my personal-notes-api project, I explored Keploy, a tool that promised automated API test generation and CI/CD integration. I wasn’t sure what to expect—but it turned out to be the cleanest integration I’ve ever done.

  4. goa

    Design-first Go framework that generates API code, documentation, and clients. Define once in an elegant DSL, deploy as HTTP and gRPC services with zero drift between code and docs.

  5. easyjson

    Project mention: Go-attention: A full attention mechanism and transformer in pure Go | news.ycombinator.com | 2025-03-03

    It depends on how long the time you spend in your c function is. cgo has a substantial overhead for calling. I tend to prefer just writing ASM functions for critical path code. You can use libraries like https://github.com/mmcloughlin/avo to make it easier to write/maintain.

  9. InfluxDB

    Project mention: Parsing Protobuf Definitions with Tree-sitter | news.ycombinator.com | 2024-08-03

    I found that some parts of a protobuf aren't captured well by protoc; specifically annotations were not well exposed to Go libraries for writing protoc plugins in 2016. I ended up having to write my own basic protobuf parser to reliably extract annotations and comments for code and documentation generation:
