Discover a growing collection of fast, dependency-free libraries and tools for Zig. From JavaScript runtimes and web application firewalls to testing, configuration, and release tooling.
Every project is written in pure Zig, has zero external dependencies unless stated otherwise, and is MIT licensed.
- Runtime and language infrastructure.
- Security and networking primitives.
- Text processing and data utilities.
- Application development tooling.
- Testing and benchmarking.
- Automated releases and changelogs.
“Batteries for Zig. Use what you need, compose what you want.”
- zig-js - A pure Zig JavaScript engine with WebAssembly, JIT compilation, a JavaScriptCore-shaped C API, and no GIL.
- zig-gc - A precise tri-color mark-sweep garbage collector with generic embedder bindings and optional compaction.
- zig-waf - An embeddable web application firewall with OWASP CRS 4 compatibility and integrations for Nginx, Caddy, Envoy, and HAProxy.
- zig-tls - Pure Zig TLS 1.3 and 1.2 for clients and servers, with non-blocking I/O, STARTTLS, session resumption, and optional 0-RTT.
- zig-injection - Allocation-free SQL injection and XSS detection compatible with libinjection 4.
- zig-regex - A regex engine combining a linear-time Thompson NFA with support for lookaround, backreferences, and named groups.
- zig-xml - A small XML and HTML tokenizer built for untrusted markup, with HTML5 character-reference decoding and no XXE.
- zig-search-engine - Typed search-engine integrations for Zig services. Typesense first.
- zig-faker - Reproducible fake data across more than 20 categories and 55 locales.
- zig-cli - Type-safe, compile-time validated command-line interfaces with routing, help output, and interactive prompts.
- zig-config - A typed configuration loader for files, environment variables, and defaults.
- zig-error-handling - A zero-overhead
Result(T, E)type with mapping, chaining, and pattern matching.
- zig-oura - Native Oura BLE authentication, lossless history sync, and raw event decoding, with C, Swift, and portable TypeScript bindings. Experimental Ring 3/4/5 interoperability; hardware validation is still required.
- zig-garmin - Garmin BLE framing, GFDI file transfer, and telemetry decoding, with native and portable bindings.
- zig-test-framework - Jest and Vitest-style testing with matchers, mocks, spies, snapshots, coverage, watch mode, and multiple reporters.
- zig-benchmarks - High-precision benchmarking with percentile statistics and clean terminal output.
- zig-bump - Update versions in
build.zig.zon, with optional commits, tags, and pushes. - zig-changelog - Generate changelogs from conventional commits.
- zig-starter - A production-ready Zig project template with testing, configuration, benchmarking, and releases included.
Most projects can be installed through Pantry or the Zig package manager.
