Generate Images from HTML with One API Call (No Puppeteer Required)

Every few months I find myself needing to generate images from HTML — OG cards for a blog, email template previews, dashboard exports, report cover pages. And every time, the path is the same: set up Puppeteer, configure it for headless, handle the Docker sandbox issues, write the render logic, deal with a crash at 2am. There's a simpler way. What the render endpoint does SnapAPI's /v1/render endpoint accepts raw HTML and returns a pixel-perfect PNG, JPEG, or WebP. One POST, one image. No browser to install, no sandbox flags, no cold-start. curl -X POST 'https://api.snapapi.tech/v1/render' \ -H 'x-api-key: YOUR_KEY' \ -H 'Content-Type: application/json' \ -d '{ "html": "<div style=\"background:#0f172a;color:#22c55e;padding:80px;font-size:48px;font-family:sans-serif\">Hello, world</div>", "width": 1200, "height": 630, "format": "png" }' \ --output card.png That's the complete workflow. Three real use cases 1. Dynamic OG card generation Instead of uploading a static image for every blog
