LumaBrowser pricing starts at zero. The Community Edition is free forever, Pro Solo is $19 per month for private templates and zero telemetry, and Enterprise Fleet is $49 per month per concurrent instance for headless and Docker deployments. Every tier is Bring Your Own Key — you supply the API keys, LumaByte never marks up tokens.
If you have Node 18+ installed, run npx lumabrowser start. The launcher downloads the right build for your OS from GitHub Releases on first run (around 150–250 MB depending on platform), caches it under ~/.lumabrowser/, and launches the app. Subsequent runs launch instantly. You can also npm install -g lumabrowser and then type lumabrowser start directly. Prefer a native installer with desktop shortcuts? Download Beta.
To build the world's most resilient database of web selectors. By using the free tier, your generated CSS templates are anonymized and shared with the community, making the Template Builder smarter for everyone.
We don't mark up API costs. You can use our built-in WebGPU extension for free local inference, or plug in your own OpenAI or Anthropic API keys. You only pay for the exact tokens you use.
