Img2Num has grown well past the point where one or two people can own it responsibly.

The codebase now spans a performance-critical C++ core, cross-language bindings (Python, JavaScript, C), a WebAssembly build pipeline, CI/CD automation, and a Docusaurus docs site. Keeping all of that high-quality and sustainable requires real ownership — not just occasional PRs.

We're looking for experienced contributors ready to take on scoped, ongoing responsibility.

Architecture Overview​

Img2Num is a layered system. Here's how the pieces fit together:

LayerPathNotes
C++ Corecore/Source of truth for all algorithms
C ABIbindings/c/Stable ABI boundary; feeds the Wasm pipeline
WebAssemblybindings/js/Built via Emscripten from the C ABI
JavaScript packagepackages/js/Safe runtime wrapper over the Wasm module
Python bindingsbindings/py/pybind11 directly on the C++ core
Python packagepackages/py/Exposes the native Python module

Open Maintainer Areas​

CI/CD​

  • GitHub Actions workflows, Docker builds, release pipelines, automated publishing.

C ABI (bindings/c)​

  • Maintain the C ABI over the C++ core. Must stay compatible with external C consumers and the Wasm pipeline.

JavaScript / WebAssembly (bindings/js, packages/js)​

  • Emscripten integration, browser and Node.js compatibility, pnpm workspace tooling, React example app.

Python (bindings/py, packages/py)​

  • pybind11 bindings, uv workspace tooling, console example app.

Docs & DX (docs/, doxygen/)​

  • Docusaurus site, Doxygen integration, tutorials, onboarding experience.

Releases & Packaging​

  • Versioning, tagging, GitHub Releases, npm and Docker Hub publishing.

Testing & Validation​

  • CI test coverage, linting/formatting enforcement, regression testing.

Internal Tooling (scripts/)​

  • Cross-platform CLI utilities, developer automation, local workflow improvements.

Maintainer Tiers​

TierMerge AccessResponsibilities
JuniorNoneReview small PRs, contribute within a defined scope
ScopedWithin their domainOwn a specific area — review, approve, maintain quality
CoreBroadCross-domain architecture, final merge authority, long-term direction

Trust is earned through consistent contributions. Everyone starts scoped.

How to Apply​

Reply to #309 with:

  • Which area(s) you want to own
  • A short summary of relevant experience
  • GitHub profile or projects (optional)

We'll follow up directly.

:::note [Edit: 20 June 2026]

Img2Num is no longer an application for converting images into color-by-number templates. Instead, it is now a library that supports C, C++, Python, and JavaScript.
