Why Zig’s Maverick Creator Challenges C, Rust, and Go After 11 Years

Andrew Kelley, the creator of the Zig programming language, started the project because he needed a high‑performance, real‑time digital audio workstation and found every mainstream language lacking: JavaScript was too abstract, Go’s C interop was poor and its garbage collector caused audio glitches, Rust’s ownership system made small changes painful, and C, while fast, was error‑prone.

“Since all the tools are so hard to use, I’ll just build my own from scratch!”

After eleven years of development, Zig has become a notable "dark horse" in systems programming, driven solely by a desire for extreme performance and control rather than corporate backing.

01. The spark of dissatisfaction

Kelley’s initial goal was a digital audio workstation; the experience of being "rejected" by existing languages led him to conclude that the problem lay in the tools themselves, not his own skill.

02. Zig’s hardcore philosophy

The core principle is "never compromise on poor user experience." Zig rejects the mindset of asking "what can my current toolchain do?" and instead asks "what can the hardware and computer fundamentally achieve, and how can any toolchain— even one you build yourself—fully exploit that potential?" This leads to a completely independent and elegant toolchain.

No complex cross‑compilation nightmares: building a Zig project is a single command: zig build Cross‑platform power: Uber uses zig cc to cross‑compile its Go code, solving long‑standing C‑code cross‑compilation issues.

03. Community and funding

Zig is maintained by the non‑profit Zig Software Foundation (a 501(c)(3) organization). The core team consists of Kelley as the only full‑time employee and five contract developers, funded entirely by donations (~$670 k in 2024), with over 90 % of revenue paid as salaries.

“I can tell any sponsor ‘sorry, we won’t change our code to suit you.’ If they pull funding, we survive.”

04. Anti‑GitHub, anti‑AI stance

Displeased with GitHub’s CI, the project migrated its repository to the German non‑profit platform Codeberg. To avoid dependence on external entities, Zig is stripping away its LLVM backend in favor of a home‑grown compiler, already achieving incremental recompilation of a million‑line codebase in under 50 ms.

The community enforces a strict ban on AI‑generated code contributions, arguing that such code is low‑value "garbage" that wastes reviewer time, undermines mentorship, and introduces nondeterministic risk to system software.

05. Real‑world adoption

Several high‑profile projects rely on Zig:

Bun – the fast JavaScript runtime uses Zig‑written glue code.

TigerBeetle – a high‑performance financial transaction database that employs Zig’s fully pre‑allocated memory model for predictable low latency.

Ghostty – a high‑performance terminal emulator by Mitchell Hashimoto, showcasing Zig’s capabilities in desktop system software.

Uber – leverages Zig’s cross‑compilation to build C components for its infrastructure.

06. Zig vs. C vs. Rust

Compared with C, Zig adds safer semantics (full stack traces on segfaults), fine‑grained overflow control (choose wrap‑around or error), and seamless migration for C developers, dramatically reducing bugs.

Against Rust, Zig’s type system is deliberately simple, emphasizing readability. Memory management is explicit via allocators, allowing developers to pick strategies like arena allocation. The mental model differs: Rust forces you to satisfy the borrow checker, while Zig lets you directly command the CPU.

07. Long‑term vision

Although Zig has not yet released a 1.0 version, Kelley explains that 1.0 would lock the language into strict backward compatibility, which he refuses in favor of a “slow‑food” development model. His goal is a language that can reliably serve software for the next 50 years.

“Human beings will never stop enjoying the act of writing code by hand. The best software comes from craftsmen who respect users as the true owners of the computer.”

The article concludes that Zig serves as a wake‑up call for developers: choose between merely avoiding crashes and pursuing predictable, solid excellence—Zig chooses the latter.
