The 30-second take

ScreenshotOne is a polished, well-known screenshot API run by a small but well-established team. It has more advanced features (async + webhook delivery, signed URLs, more SDKs) and a longer track record. Solid choice.

aiSnapApi is leaner, simpler, and slightly cheaper at most tiers. We don't have every advanced feature ScreenshotOne does — and we're up-front about that below. We're a great fit if you want a no-nonsense screenshot API and you're not yet bumping into ScreenshotOne's advanced features.

Honestly? Both products are good. The decision usually comes down to price sensitivity and whether you need async / signed-URL delivery.

Migrating from ScreenshotOne: minimal changes

Both APIs are GET-based with similar parameters. Migration is usually a base-URL swap and an auth-header change.

Before (ScreenshotOne)

curl "https://api.screenshotone.com/take?access_key=KEY&url=https://example.com&full_page=true&format=png" \
  -o screenshot.png

After (aiSnapApi)

curl "https://api.aisnapapi.com/v1/screenshot?url=https://example.com&full_page=true&format=png" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -o screenshot.png

Note: if you currently rely on signed URLs or webhook delivery, you'll want to wait until those features land on aiSnapApi (on the roadmap) or stay on ScreenshotOne.
