ShotWolf - Screenshot & render API

ShotWolf is a screenshot and rendering API for developers. Send any URL or raw HTML and get back a pixel-perfect screenshot, PDF, scroll-recording video, or a ready-made social/device mockup - with a single call. No Playwright fleet to babysit, no headless-Chrome ops. CAPTURE FORMATS - Full-page or viewport screenshots (PNG, JPG, WebP) - HTML-to-PDF with page formats (A4, Letter, and more) + landscape - Scroll-recording video (GIF / MP4) - auto-scrolls the page and records it - Open Graph images (1200x630 @2x retina) from templates - Device & social mockups: iPhone frames, Instagram post/profile, Facebook / Google / LinkedIn ad mockups RENDERING CONTROLS - Capture from a live URL or paste raw HTML - Device presets (iPhone, desktop, custom viewport), dark mode, full-page - Ad / tracker / cookie blocking + automatic cookie-banner dismissal for clean shots - Scripted actions (click, type, scroll, wait-for-selector) before capture - Custom user-agent, delays, wait conditions, image quality BUILT FOR AUTOMATION - Synchronous (image inline in ~1-4s) or async (queue + poll or webhook) - HMAC-signed webhooks on completion, with built-in SSRF protection - Idempotency-Key header - safe retries, never double-charged - Batch capture and screenshot diffing - cache_ttl to dedupe identical requests - Push results straight to your own S3 / R2 bucket - Public, revocable share URLs for every capture - OpenAPI spec + docs with curl / Node / Python / Ruby / PHP / Go samples USE CASES Automated OG / link-preview images, PDF invoices and reports, visual regression testing, email and newsletter previews, social-media mockups, thumbnail generation, page archiving and monitoring.
