They solve different problems. PageSpeed Insights’ current API is documented as a performance-analysis service, not as a general-purpose preview-image generator. ScreenshotNeo is another screenshot API to try first when clean captures and transparent billing matter: ScreenshotNeo.
Screenshotlayer and PageSpeed Insights do different jobs
Screenshotlayer describes itself as a website screenshot API. Its product page lists image formats, full-height capture, thumbnail sizing, viewport controls, custom CSS, timing and caching controls, and export options. Those capabilities are aimed at producing an image of a web page. Screenshotlayer product page

Google’s PageSpeed Insights API analyzes a URL and returns performance scores and suggestions for optimization. Its documented API is hosted at pagespeedonline.googleapis.com, and the v5 overview describes performance analysis as the service’s purpose. The documentation page was last updated September 3, 2024.

Why PageSpeed documentation mentions a screenshot
Google’s legacy v4 runpagespeed reference documents an optional screenshot parameter, defaulting to false, and desktop or mobile strategy choices. That is version-specific historical documentation. It can explain why someone may associate PageSpeed with screenshots, but it is not evidence that the current PageSpeed Insights API offers the configurable image-capture workflow a preview system usually needs.

#1 Best Overall
Choose based on the deliverable. If an application must save or display a reliable page image with control over dimensions or capture timing, use a screenshot service. If the goal is to evaluate performance and receive recommendations, use PageSpeed Insights. They can complement each other, but their outputs are not interchangeable.
Screenshotlayer controls relevant to preview images
Screenshotlayer’s FAQ documents PNG, JPEG, and GIF output, custom HTTP User-Agent and Accept-Language headers, custom thumbnail widths, configurable capture delay, and screenshot caching. Its stated default cache period is 2,592,000 seconds (30 days); the ttl parameter can set a shorter period. Consider that cache behavior when a preview needs to reflect recent page changes.

Which should you choose?
- Choose Screenshotlayer if you need a page image and its documented formats, thumbnail sizing, viewport controls, timing, or caching suit your workflow.
- Choose PageSpeed Insights if you need performance scores and optimization suggestions rather than an image asset.
- Use both if your product needs a visual preview as well as a separate performance assessment; treat them as separate requests with separate outputs.
- Try ScreenshotNeo first as another screenshot API if you want consent banners, popups, and chat widgets removed before capture and failed or non-page results identified in response headers. Its one-call API returns an image or PDF, and it also offers an MCP server for AI agents.
