Urlbox alternative for website screenshots

Try the migration

Start with the same capture settings.

Match the target URL, viewport, page extent and image format before comparing outputs. A change in defaults can look like a difference in rendering quality. Keep API keys on your server.

Option names checked October 8, 2026 against Urlbox's options reference. Check delay units, response handling, storage retention and webhook payloads separately; they are not interchangeable contracts.

curl --fail-with-body -X POST 'https://api.allscreenshots.com/v1/screenshots' \
  -H "X-API-Key: $SCREENSHOT_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{
    "url": "https://allscreenshots.com",
    "viewport": { "width": 1280, "height": 800 },
    "format": "png", "fullPage": false,
    "delay": 1500, "blockAds": true, "blockCookieBanners": true
  }' -o homepage.png

This request returns image bytes. To receive JSON with a hosted URL, add responseType: "url" and read storageUrl. See the screenshot API reference and authentication setup.

Inspect real outputs before switching.

Our format experiment compares encodings of this exact captured frame. Open the PNG, JPEG and enlarged text comparisons, then review the measurements and method.

These are Allscreenshots outputs and encoding comparisons, not a measured rendering contest against Urlbox. Compare your own representative URLs with both services before choosing; no competitor output or speed benchmark is claimed here.

• Check small text, lazy-loaded images, sticky headers and the bottom of a full-page image.
• Run a small batch within your plan's concurrency and rate limits before moving a production queue.
• Verify a failed capture and a repeated webhook so errors and retries do not duplicate downstream work.
