'''Zig''' is an [[Imperative programming|imperative]], [[General-purpose programming language|general-purpose]], [[statically typed]], [[Compiled language|compiled]] [[System programming language|system]] [[programming language]] designed by Andrew Kelley.<ref>{{Cite web |date=2021-10-19 |title=Taking the warts off C, with Andrew Kelley, creator of the Zig programming language |url=https://sourcegraph.com/podcast/andrew-kelley |access-date=2024-04-18 |website=Sourcegraph |language=en}}</ref> It is [[free and open-source software]], released under an [[MIT License]].<ref>{{Cite web|url=https://github.com/ziglang/zig|title=ziglang/zig|website=GitHub|language=en|access-date=2020-02-11}}</ref>

A major goal of the language is to improve on the [[C (programming language)|C language]]<ref name="roadtozig1.0" /><ref>{{Cite web|url=https://ziglang.org/#Zig-competes-with-C-instead-of-depending-on-it|title=The Zig Programming Language|website=Ziglang.org|access-date=2020-02-11}}</ref> (also taking inspiration from [[Rust (programming language)|Rust]]<ref>{{Cite web |title=Zig programming language |url=https://sudonull.com/post/3683-Zig-programming-language |access-date=2020-02-11 |website=SudoNull |language=en}}</ref>{{sfn|Yegulalp|2016}}), with the intent of being even smaller and simpler to program in, while offering more functionality.<ref>{{Cite web |date=2017-10-31 |title=Zig has all the elegant simplicity of C, minus all the ways to shoot yourself in the foot |url=https://jaxenter.com/zig-language-kelley-interview-138517.html |archive-url=https://web.archive.org/web/20171101231710/https://jaxenter.com/zig-language-kelley-interview-138517.html |archive-date=2017-11-01 |access-date=2020-02-11 |website=JAXenter |language=en-US}}</ref> The improvements in language simplicity relate to flow control, [[Function (computer programming)|function calls]], [[Library (computing)|library]] imports, [[Declaration (computer programming)|variable declaration]] and [[Unicode]] support. Further, the language makes no use of [[Macro (computer science)|macros]] or [[preprocessor]] instructions. Features adopted from modern languages include the addition of [[compile time]] [[generic programming]] [[data type]]s, allowing functions to work on a variety of data, along with a small set of new [[compiler]] directives to allow access to the information about those types using [[reflective programming]] (reflection).<ref name=zig>{{Cite web|url=https://ziglang.org/|title=The Zig Programming Language|website=Ziglang.org|access-date=2020-02-11}}</ref> Like C, Zig omits [[Garbage collection (computer science)|garbage collection]], and has [[manual memory management]].<ref name=zig /> To help eliminate the potential errors that arise in such systems, it includes [[option type]]s, a simple [[Syntax (programming languages)|syntax]] for using them, and a [[unit testing]] framework built into the language. Zig has many features for [[Low-level programming language|low-level programming]], notably packed structs (structs without padding between fields), arbitrary-width integers<ref>{{Cite web |url=https://www.theregister.co.uk/2020/04/24/llvm_project_adds_support_for/ |title=Keen to go _ExtInt? LLVM Clang compiler adds support for custom width integers |last1=Anderson |first1=Tim |date=2020-04-24 |website=www.theregister.co.uk |language=en |access-date=2024-12-30}}</ref> and multiple pointer types.<ref name="zigdocumentation">{{Cite web|url=https://ziglang.org/documentation/master/|title=Documentation|website=Ziglang.org|access-date=2020-04-24}}</ref>

The main drawback of the system is that, although Zig has a growing community, as of 2025, it remains a new language with areas for improvement in maturity, ecosystem and tooling.<ref name="logrocket">{{cite web |last=Chigozie |first=Oduah |title=Comparing Rust vs. Zig: Performance, Safety, and More |url=https://blog.logrocket.com/comparing-rust-vs-zig-performance-safety-more/ |website=LogRocket Blog |date=2024-06-04 |access-date=2024-07-16}}</ref> Also the learning curve for Zig can be steep, especially for those unfamiliar with low-level programming concepts.<ref name="logrocket"/> The availability of learning resources is limited for complex use cases, though this is gradually improving as interest and adoption increase.<ref name="logrocket"/> Other challenges mentioned by the reviewers are interoperability with other languages (extra effort to manage data marshaling and communication is required), as well as manual memory deallocation (disregarding proper memory management results directly in memory leaks).<ref name="logrocket"/>
