Introduction
SnapSharp is a screenshot and image generation API built for developers who ship fast. One platform, five core capabilities, five SDKs, a CLI, and an interactive API reference.
Core capabilities
Screenshots — Capture any website as PNG, JPEG, or WebP. Full page, mobile viewports, dark mode, retina, ad blocking, custom CSS/JS injection, stealth mode, and proxy support.
OG Images — Generate social preview images from built-in or custom templates. Blog posts, social cards, product cards — one API call, perfect 1200×630 every time.
HTML to Image — Render any HTML/CSS to a pixel-perfect image. Certificates, banners, invoices — bring your own design.
Site Audit — Extract design tokens from any website: color palette, fonts with weights, heading hierarchy, tech stack detection (14+ frameworks), metadata, and accessibility. Output as JSON, PNG visual card, or PDF report. Docs →
Website Monitoring — Automated scheduled screenshots with pixel-level visual diff. Golden baseline comparison, load time alerts, HTTP status change detection, maintenance windows, public status pages, and snapshot export. Docs →
