I’m the author and maintainer of wyw-in-js — a build-time CSS-in-JS toolkit focused on predictable behavior, correctness, and long-term stability.

Unlike runtime libraries, wyw-in-js performs a significant amount of work during the build phase.
This requires static analysis of effectively unbounded user code, which makes the problem space fundamentally fragile and full of edge cases.

My goal with this project is not to chase features, but to:

  • keep existing setups working across releases;
  • catch regressions early;
  • validate real-world codebases before changes are published;
  • and gradually improve performance without sacrificing correctness.

Sponsorship directly supports:

  • ongoing maintenance and bug fixing;
  • compatibility testing against real projects;
  • careful architectural work (ESM-only transition, Rust/oxc migration);
  • and long-term sustainability of the project.

If your project relies on wyw-in-js in production, sponsorship is the most reliable way to ensure it keeps working as your codebase and tooling evolve.

@Anber

Monthly funding for wyw-in-js and Linaria helps me invest consistent time into performance work (profiling + hot-path optimization), a gradual Rust rewrite of critical modules (reliability, predictable speed, memory safety), and steadier maintenance (issue triage, PR reviews, docs, and regular releases). Expect a short monthly progress update.

Compatibility & Stability Support (per hour)

Early compatibility testing and stability support for projects using the library.

What’s included:

  • running the library against your project before releases;
  • early detection of breaking edge-cases related to build-time analysis;
  • feedback on problematic patterns and suggested workarounds;
  • direct communication channel for compatibility issues.

Typical effort:

  • simple projects (repository accessible without VPN, existing test suite): ~1 hour per month;
  • more complex setups and custom workflows can be discussed individually.

Access to private repositories is handled under NDA if required.
