Mergo
Mergo: merging Go structs and maps since 2013
A helper to merge structs and maps in Golang. Useful for configuration default values, avoiding messy if-statements. Mergo merges same-type structs and maps by setting default values in zero-value fields. Mergo won't merge unexported (private) fields. It will do recursively any exported one. It also won't merge structs inside maps (because they are not addressable using Go reflection). -

moq
Interface mocking tool for go generate
Moq is a Go interface mocking tool designed to generate test-friendly mock structs from existing interfaces. It is commonly used with go generate so teams can keep mock implementations synchronized with their source interfaces. Instead of relying on a large mocking framework, Moq creates straightforward Go code that can be inspected, edited, and used directly in tests. The generated structs allow developers to define function behavior for each mocked method. -

gopsutil
psutil for golang
gopsutil tag policy is almost same as Semantic Versioning but automatically increases like Ubuntu versioning. gopsutil aims to keep backward compatibility until a major version change. Tagged at the end of the month, but if there are only a few commits, it can be skipped. All works are implemented without cgo by porting C structs to golang structs. -
PRTG Catches Network Issues Before They Cause DowntimeReactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

Scany
Library for scanning data from a database into Go structs and more
...It provides great control and efficiency in your queries, but here is a problem: you need to manually iterate over database rows and scan data from all columns into a corresponding destination. It can be error-prone verbose and just tedious. scany aims to solve this problem. It allows developers to scan complex data from a database into Go structs and other composite types with just one function call and doesn't bother with row iteration. -

Go QueryString
go-querystring is Go library for encoding structs into URL query
go-querystring is a lightweight Go library developed by Google for encoding Go structs into URL query strings. It simplifies the process of constructing URLs with typed parameters, offering a clean, type-safe approach to building query strings programmatically. The library’s query package exposes a single Values() function that converts struct fields (tagged with url tags) into properly encoded query parameters. It is particularly useful for APIs or HTTP clients that represent query parameters as structs—such as in the go-github client library. ... -

go-restful
Package for building REST-style Web Services using Go
...Filters for intercepting the request-response flow on Service or Route level. Request-scoped variables using attributes. Route errors produce HTTP 404/405/406/415 errors, customizable using ServiceErrorHandler(...). Request API for reading structs from JSON/XML and accessing parameters (path, query, header). Customizable gzip/deflate readers and writers using CompressorProvider registration. There are several hooks to customize the behavior of the go-restful package. -

go-jsonschema
A tool to generate Go data types from JSON Schema definitions
go-jsonschema is a tool to generate Go data types from JSON Schema definitions. This tool generates Go data types and structs that corresponds to definitions in the schema, along with unmarshalling code that validates the input JSON according to the schema's validation rules. -

q Go
Quick and dirty debugging output for tired Go programmers
...Type q.Q instead of fmt.Printf and your variables will be printed like the provided example. Faster to type, pretty-printed vars and expressions. Easier to see inside structs, doesn't go to noisy-ass stdout. It goes to $TMPDIR/q. q Go offers pretty colors! -

Participle
A parser library for Go
Participle is a parser library for Go that lets developers define parsers in an idiomatic Go style. It uses annotated Go structs to describe grammar rules and produce the parsed AST at the same time. This approach feels familiar to Go developers because it resembles the way struct tags are used for formats such as JSON. The library supports a rich grammar syntax with captures, recursive captures, grouping, alternatives, repetition, lookahead, and literal matching. -

wasm-bindgen
Facilitating high-level interactions between Wasm modules and Js
wasm-bindgen is a foundational Rust tool that enables seamless interoperability between Rust and JavaScript by generating the necessary bindings and glue code for WebAssembly modules. It allows developers to write performance-critical code in Rust, compile it to WebAssembly, and then expose functions, structs, and APIs directly to JavaScript in a natural and idiomatic way. The tool automates the process of bridging differences between Rust’s type system and JavaScript’s dynamic environment, making cross-language integration significantly easier. One of its key design principles is efficiency, following a “pay only for what you use” model where only the required bindings are generated, minimizing unnecessary overhead. ... -

ozzo-validation
An idiomatic Go (golang) validation package
...It has the following features. Use normal programming constructs rather than error-prone struct tags to specify how data should be validated. Can validate data of different types, e.g., structs, strings, byte slices, slices, maps, and arrays. Can validate custom data types as long as they implement the Validatable interface. Can validate data types that implement the sql.Valuer interface (e.g. sql.NullString). Customizable and well-formatted validation errors. Error code and message translation support. Provide a rich set of validation rules right out of the box. ... -

CXX
Safe interop between Rust and C++
CXX is a library that offers safe interop between Rust and C++. It provides a safe mechanism for calling C++ code from Rust and vice versa, one that is protected from the many possible things that can go wrong when bindgen or cbindgen is used to generate unsafe C-style bindings. The general idea of CXX is to define the signatures of both sides of the FFI boundary embedded together in one Rust module. CXX gets a complete picture from this of the boundary, and through it is able to perform... -

Functors.jl
Parameterise all the things
Functors.jl provides tools to express a powerful design pattern for dealing with large/ nested structures, as in machine learning and optimization. For large machine learning models, it can be cumbersome or inefficient to work with parameters as one big, flat vector, and structs help manage complexity; but it is also desirable to easily operate over all parameters at once, e.g. for changing precision or applying an optimizer update step. -

Bevy
A refreshingly simple data-driven game engine built in Rust
...All engine and game logic uses Bevy ECS, a custom Entity Component System. Massively Parallel and Cache-Friendly. The fastest ECS according to some benchmarks. Components are Rust structs, Systems are Rust functions. Queries, Global Resources, Local Resources, Change Detection, Lock-Free Parallel Scheduler. Bevy is still in the very early stages of development. APIs can and will change (now is the time to make suggestions!). Important features are missing. Documentation is sparse. Please don't build any serious projects in Bevy unless you are prepared to be broken by API changes constantly. ... -

high-performance-go
high performance coding with golang
...It teaches developers how to measure performance before attempting optimization. Benchmarking and pprof are used to identify bottlenecks and compare implementation choices. The material examines strings, slices, loops, reflection, empty structs, and memory alignment. It also explores concurrency performance through mutexes, goroutine control, sync.Pool, sync.Once, and sync.Cond. Additional chapters cover compiler optimization, escape analysis, dead-code elimination, binary size, and common Go traps.
