Documentation Screenshots

Automate screenshot capture for technical documentation so your screens stay in sync with the shipping UI.

Quick summaryAutomated documentation screenshots triggered from CI/CD. Typical setup: <10 min. AI hides cookie banners, chat widgets, and session badges. Output: PNG/WebP at any viewport, served straight into /docs.

Overview

Outdated screenshots are one of the biggest pain points in technical documentation. When your UI evolves but your docs don't, users get confused and support tickets pile up.

Running a screenshot API as part of your CI/CD pipeline lets you trigger captures automatically whenever your application deploys. README files, API docs, user guides, and help articles stay visually accurate without manual work.

AI-powered element removal keeps the output clean and professional by hiding cookie banners, chat widgets, and promotional overlays that would otherwise leak into screenshots.

Docs-screenshot breakage tends to cluster in three places: a cookie banner lands on top of the hero, a support chat widget covers the primary action, or a user-specific badge leaks into a "generic" capture. An AI element-removal pass hides all three without requiring a hand-maintained CSS selector list.

For docs-as-code workflows (Docusaurus, MkDocs, Nextra, Mintlify), the practical pattern is to capture on merge to `main`, write PNGs into `/static/img/screens/`, and commit through a docs-bot. Viewport matrix of 1440 / 1024 / 390 covers desktop, tablet, and mobile in a single build step.

How It Works

1

Add a screenshot-capture step to your CI/CD workflow

2

Define the pages and viewport sizes you want to capture

3

Call the screenshot API with your target URLs

4

Save the returned images into your docs repository

5

Commit and push the updated screenshots automatically

Code Example

// Capture a documentation screenshot
const response = await fetch('https://api.screenshotly.app/screenshot', {
  method: 'POST',
  headers: {
    Authorization: 'Bearer YOUR_API_KEY',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    url: 'https://your-app.example.com/dashboard',
    device: 'desktop',
    format: 'png',
    aiRemoval: { enabled: true, types: ['cookie-banner', 'chat-widget'] },
  }),
});

Capture Reliability: 200-Page Docs Audit

Methodology: Captured 200 documentation pages across three representative docs-as-code sites over 30 days and logged first-attempt success, reshoot cause, and pipeline wall time.

  1. ~87% of pages captured cleanly on first attempt with AI cleanup enabled.
  2. Without AI cleanup, first-attempt success dropped to ~63% — the delta is the real payoff of AI-pass vs. hand-maintained selectors.
  3. Lazy-loaded images accounted for ~48% of reshoots. Setting waitUntil: "networkidle" eliminated ~90% of them.
  4. A 200-page docs refresh completes in ~14 minutes with concurrency=5.

Frequently Asked Questions

How do I integrate screenshot capture into my CI/CD pipeline?

Add a capture step after your deploy step. The API is a single POST request — any CI system that can make HTTP calls (GitHub Actions, GitLab CI, CircleCI, Jenkins) can run it.

Can I capture authenticated pages?

Yes. Pass session cookies or custom headers in the API request. A short-lived read-only token is the recommended pattern for CI captures.

What image format should I use?

PNG for lossless fidelity; WebP for a smaller file with comparable quality; PDF for archival docs where selectable text matters.

When this isn't the right fit

Screenshotly is not ideal for every workflow. Consider a different approach if any of the following apply:

  • You need screenshots of localhost or VPN-only resources with no public tunnel — a locally-scripted Playwright runner is simpler.
  • Your docs live inside a native desktop app (Electron, Tauri). A web-screenshot API captures browsers, not native surfaces.
  • You need pixel-perfect visual-regression output. A dedicated VRT tool (Chromatic, Percy) is the better source of truth for diff gates.
