Batteries for Zig.
Fast, dependency-free libraries and tools — from a JavaScript engine and a WAF down to the small pieces you reach for every day.
Discord · Zig · Repositories
Every library here is pure Zig, zero external dependencies unless stated, and MIT licensed. They compose well together but none of them require the others.
| Project | What it is |
|---|---|
| zig-js | A pure-Zig JavaScript engine with a JavaScriptCore-shaped C API. Passes the configured test262 corpus 53,175/53,175 and the ten-profile WebAssembly matrix, with a JIT and no GIL. |
| zig-gc | A precise, tri-color mark-sweep garbage collector, generic over an embedder binding (MMTk-style). Non-moving by default, with opt-in failure-atomic compaction. |
| Project | What it is |
|---|---|
| zig-waf | An embeddable web application firewall and fleet platform targeting ModSecurity 3 / Coraza semantics with OWASP CRS 4 compatibility. Ships a reverse proxy, a C connector ABI, and Nginx/Caddy/Envoy/HAProxy integrations. |
| zig-tls | Pure Zig TLS 1.3 and 1.2 — client and server, non-blocking I/O, STARTTLS, PSK resumption and opt-in 0-RTT, with optional AArch64/x86_64 AES-GCM assembly. |
| zig-injection | Allocation-free SQLi and XSS detection, behaviorally compatible with libinjection 4. Idiomatic Zig plus a stable C ABI. |
| Project | What it is |
|---|---|
| zig-regex | A regex engine pairing a linear-time Thompson NFA with a backtracking engine for lookaround, backreferences, and named groups. |
| zig-xml | A small, lenient, allocation-light XML/HTML pull tokenizer with HTML5 character-reference decoding. Built for untrusted markup — no DTDs, no XXE. |
| zig-search-engine | Search-engine integrations for Zig services. Declare a collection as a schema; a driver builds the engine-native structure. Typesense first. |
| zig-faker | Realistic fake data for tests, seeds, and prototypes — 20+ categories across 55 locales, with reproducible seeding. |
| Project | What it is |
|---|---|
| zig-cli | Type-safe, compile-time validated CLIs. Define options as a struct and get parsing, routing, help output, and interactive prompts for free. |
| zig-config | A smart configuration loader — local files, home directory, env vars, and defaults, deep-merged into your typed config struct. |
| zig-error-handling | A Result(T, E) type inspired by Rust and neverthrow: chainable map / andThen, pattern matching, and zero runtime overhead. |
| Project | What it is |
|---|---|
| zig-test-framework | Jest/Vitest-style testing for Zig: describe/it, rich matchers, mocks and spies, snapshots, coverage, watch mode, and 5 reporters. |
| zig-benchmarks | A mitata-inspired benchmark harness with high-precision timing, percentile statistics, and beautiful CLI output. |
| zig-bump | One command to bump the version in build.zig.zon — interactive, with optional commit, tag, and push. |
| zig-changelog | Generate changelogs from conventional commits, as a library or a CLI. |
| zig-starter | A production-ready template wiring the above together, so a new library or CLI starts with tests, config, and releases already working. |
Most projects install through Pantry or the Zig package manager:
pantry add zig-regex// build.zigconstregex=b.dependency("regex", .{ .target=target, .optimize=optimize });
exe.root_module.addImport("regex", regex.module("regex"));Check each repository's README for its exact module name and minimum Zig version.
Issues and pull requests are welcome on every repository. Good first steps: pick an open issue, add a test case, or improve documentation. If you are unsure where something belongs, ask in Discord.
