SnapRender: Screenshot API for Developers

Quick Start

Sign up at app.snap-render.com to get an API key, then make a single GET request:

curl -o screenshot.png \
  "https://app.snap-render.com/v1/screenshot?url=https://example.com" \
  -H "X-API-Key: YOUR_API_KEY"

Response: raw PNG bytes. Add response_type=json to get a base64 data URI instead.

Features

Pricing

All features are included on every plan. The only difference is screenshot volume. No feature gating, no hidden limits.

How SnapRender Compares

Comparison based on publicly available pricing pages as of March 2026. All services provide screenshot API functionality with varying feature sets.

ScreenshotOne and Urlbox are established services with broader feature sets (e.g., geolocation, retina rendering). SnapRender focuses on simplicity and value. Self-hosted Puppeteer gives full control but requires DevOps effort.

Code Examples

Common Use Cases

• Website thumbnails for directories and dashboards -- generate preview images for link aggregators, bookmark managers, and SaaS dashboards without running your own browser.
• Social media link previews -- create OG images when a site's own meta tags are missing or broken. Useful for chat apps and content aggregators.
• Automated visual QA -- capture screenshots after each deploy and compare against baselines. Catch CSS regressions before users do.
• Compliance archival -- take timestamped captures of web pages for legal, regulatory, or contractual evidence.
• AI agent web vision -- give LLM-powered agents the ability to see any webpage. Works with MCP (Claude), OpenAI tool_call, LangChain, and CrewAI.
• Competitive monitoring -- track competitor landing pages, pricing changes, and feature updates with scheduled captures.

AI Agent Integration

SnapRender is built for AI agents that need to see the web. Three integration paths:

• MCP Server -- @snaprender/mcp-server on npm. Works with Claude and any MCP-compatible agent.
• OpenAPI / ChatGPT Actions -- OpenAPI spec at app.snap-render.com/openapi.json. Import directly into ChatGPT.
• REST API -- simple GET request with response_type=json returns base64 image. Works with any HTTP client.
