Screenshot API for Go
Capturing website screenshots from Go usually means running and scaling a headless browser yourself. With Snapraven you skip all of that — grab a screenshot with Go’s standard net/http client.
What you can build with Go
Add screenshot capture to a high-throughput Go service, a CLI, or a worker that snapshots many sites — using only the standard library, with no CGO or browser dependency.
Example in Go
req, _ := http.NewRequest("GET",
"https://api.snapraven.app/v1/screenshot?url="+url.QueryEscape(target), nil)
req.Header.Set("x-api-key", key)
resp, _ := http.DefaultClient.Do(req)
png, _ := io.ReadAll(resp.Body)
That's the entire integration. Snapraven renders the page in a real Chromium browser and
returns a PNG or JPEG. Add fullPage=true
for the full scrollable page, or width/height for custom viewports.
💡 Tip for Go
Reuse a single `http.Client` with a sensible `Timeout`, and for bulk work fan out with goroutines bounded by a semaphore so you don’t overwhelm your own process.
Why developers use Snapraven with Go
- ✓ No headless Chrome to install, run, or scale.
- ✓ A single HTTP request — works anywhere Go can make a fetch.
- ✓ Full-page capture, custom viewport, PNG or JPEG.
- ✓ Free tier with 100 requests per month to start.
Go screenshot API — FAQ
How do I capture many URLs fast?
Launch goroutines bounded by a buffered channel (a semaphore) so you process URLs concurrently without unbounded fan-out.
Should I set a timeout?
Yes — configure `http.Client{Timeout: …}` so a slow target page doesn’t hang your worker.
