Cross-platform WebGPU/WebGL2 compatibility layer
A compatibility abstraction layer that lets developers write WebGPU code once and automatically falls back to WebGL2 on unsupported platforms, handling the inconsistencies between implementations. Addresses the current fragmentation where WebGPU crashes on Chrome for Linux and is unavailable on Firefox, forcing developers to maintain dual codebases.
Why this matters
You want to use WebGPU for your next web graphics project to take advantage of its modern features, but you discover it's not reliable across platforms. Firefox on Linux doesn't support it out of the box, and even Chrome crashes frequently. You're forced to either limit your audience or maintain two separate codebases — one for WebGPU and one for WebGL2. Every time you find a WebGPU bug on one platform, you have to write platform-specific workarounds, eating into development time that should go toward building your actual product.
- · Built for Web graphics developers who want to use WebGPU features but need to support browsers and platforms where WebGPU is unavailable or unstable.
- · Most likely monetization: Open source core with paid enterprise support and premium features.

Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1This is a transitional problem — as WebGPU matures across all browsers within 2-3 years, the need for a compatibility layer disappears entirely, giving the product a short shelf life
- 2Major established libraries like Three.js and Babylon.js already have teams working on WebGPU/WebGL2 abstraction layers, making it hard for a new entrant to compete on completeness
- 3Maintaining two rendering backends in sync is extremely complex and bug-prone, potentially requiring more engineering effort than the market can sustain for a transitional tool
Evidence Summary
How AI synthesized this insight — no verbatim quotes
One commenter questioned the choice of WebGL2 over WebGPU, and another responded with specific platform issues: WebGPU is unavailable on Firefox for Linux and crashes frequently on Chrome. This confirms a real cross-platform compatibility gap during the WebGPU transition period. However, the discussion suggests this is a temporary problem that will resolve as WebGPU matures, limiting long-term commercial viability. Approximately 2 commenters discussed this challenge.
