Local, language-agnostic WebGPU highlighting for code GitHub leaves uncolored. Syntax highlighting for the languages GitHub doesn’t recognize yet. Exploring a new language, building your own, or reading AI-generated code? Universal GitHub Highlighting adds syntax colors automatically when GitHub leaves code plain. No language selection, custom grammars, or configuration needed. - Automatic highlighting for repository files, supported pull request diffs, and Markdown code blocks. - Respects GitHub’s colors. Existing syntax highlighting stays intact by default. - Fits your theme. Colors follow GitHub’s light and dark modes. - Keeps GitHub working. Preserves source text, copying, line links, and code navigation. - Simple controls. Toggle highlighting, force it for a file, or adjust the smooth color transition. Everything runs locally on your GPU using a small bundled model powered by gpu-lexer. No code uploads, external inference services, accounts, or telemetry. Requires desktop Chrome with WebGPU support. Initial GPU startup may take a moment. Very large files are skipped, some diff layouts may be unsupported, and model-predicted colors can occasionally be imperfect. An independent, open-source extension, not affiliated with GitHub.
