FAQ

How fast are renders?

Typical synchronous screenshots return in 1.5–3 s; PDFs from HTML are usually under 1 s. Cached renders return in tens of milliseconds. p95 targets: screenshot < 4 s, PDF < 6 s.

What counts as a render?

One successful screenshot, PDF, or image generation. Failed renders and cache hits are free. All three products draw from the same monthly pool.

Do you support async processing?

Yes — pass async: true to get a job id immediately, then poll /v1/jobs/:id or receive a signed webhook when it finishes.

Can I embed renders without a backend?

Yes — signed URLs let you put a render directly in an <img> tag or email template. Signatures are HMAC-SHA256 with a per-key secret.

What about abuse and security?

Every fetched URL — including every redirect hop and subresource — is checked against private/reserved IP ranges. Browsers run sandboxed in isolated containers. See the url_blocked reference.
