Why Automate Screenshots?

Manual screenshots don't scale. Whether you need daily dashboard snapshots, CI/CD visual diffs, OG image previews, or monitoring alerts — a scriptable screenshot API saves hours.

SnapShot API is the simplest way to automate this. One endpoint, instant key, no signup.

Get a Key (No Signup)

curl https://snapshot-api-production-1374.up.railway.app/key

That's it. A JSON response with your key and referral_code. No email, no OAuth, no billing info.

Take a Screenshot

curl "https://snapshot-api-production-1374.up.railway.app/screenshot?url=https://example.com&key=YOUR_KEY" > screenshot.png

The API returns a full-page PNG. Works for any public URL.

Use Cases

CI/CD Visual Regression
