No headless browser to maintain, no Puppeteer crashes at 3am, no IP blocks when your cron job fires.
Use any CSS framework, custom fonts, dynamic data. Full Tailwind CDN support. Your design, your control.
One API call with your HTML and dimensions. Authenticated with your API key — no IP-based limits, no surprise rate blocks.
