Screenshot API in Go: Capture Screenshots and PDFs with net/http Go services often need to capture web pages: generate invoice PDFs, take screenshots for website monitoring, render HTML reports. The typical path — shelling out to Chrome or embedding a headless browser — adds fat binaries, cgo dependencies, and memory management headaches to a language valued for lean deployments. A screenshot API avoids all of that. You make a POST request, get back binary image or PDF data, write it to disk or stream it. No Chrome. No cgo. No Docker overlay magic. This guide shows how to use PageBolt from Go using only the standard library. Why a Screenshot API in Go Specifically? Go's biggest advantages — small binaries, fast startup, easy cross-compilation — get undermined the moment you add a headless browser dependency. Chrome's shared libraries are not small. Running Puppeteer from a Go service means spawning a Node.js process. Embedding rod or chromedp works, but you're shipping ~100 MB of Chrom
