Integrate your way
Official SDKs and native tools for AI agents.
Official SDK
Node.js
Typed capture, batch, diff, and webhook helpers.
Official SDK
Java
A small JVM client, without a local browser.
HTTP API
JavaScript
Use fetch from your server-side workflow.
Command line
cURL
A direct route into scripts, cron, and CI.
AI agents
Remote MCP
Connect Claude, Codex, Cursor, Copilot, or ChatGPT.
Built for AI workflows
Give agents evidence, not another browser to maintain.
A single MCP connection gives an agent the right tool for visual review, page text, comparisons, or queued captures.
Connect the MCP server- 1
Connect
Add the secure remote MCP endpoint to the client where your agent works.

Input and output
Turn a URL or HTML payload into the artifact your workflow needs.
Use one API surface for screenshots, PDFs, visual diffs, metadata, and LLM-ready content extraction.
PDF export
Generate documents with page format, orientation, and background graphics for invoices, reports, and evidence.
Content extraction
Return markdown, HTML, plain text, and metadata beside a screenshot for AI agents and analysis workflows.
Visual diff
Compare two URLs pixel-by-pixel and return changed pixels, diff percentage, and a highlighted diff image.
Batch capture
Render up to 10 URLs in one request with bounded parallelism through the browser pool.
Async webhooks
Queue heavier jobs, return a job ID immediately, and notify your application when the capture finishes.
The browser work, handled
Ship the output. Skip the browser cluster.
Instead of maintaining browser processes, queues, retries, image transforms, and storage glue, send SnapshotFlow a URL or HTML payload and choose what should come back.
Your request
URL + capture options
GET /screenshot?url=example.com
&full_page=true&extract_content=true
&full_page=true&extract_content=true
01
Render
Load the real page in a browser.
02
Prepare
Apply viewport and cleanup options.
03
Deliver
Return, store, cache, or webhook.
Clean captures
Screenshots without the clutter that ruins reports.
Block ads, trackers, cookie banners, fonts, media, or your own selectors so every capture is consistent enough for audits, research, and customer-facing workflows.
Ad and tracker blockingGhostery-powered rules keep noisy pages under control.
Device emulationMobile viewport, timezone, geolocation, and dark mode.
Custom CSS and JSInject page fixes before the screenshot is taken.
Deterministic cache keysEvery output-changing option becomes part of the cache key.

Built around real workflows
Screenshots become more useful when they move with your work.
Capture the page, keep its context, and route the result into QA, monitoring, AI, or customer-facing products.
QA & releases
Catch visual changes before users do.
Compare two URLs pixel by pixel and return a diff image, changed-pixel count, and percentage your CI workflow can act on.
Visual regression testing
Release diff
Changes found
Changed pixels14,320
Diff1.40%
Keep a visual record of what changed.
Schedule repeat captures, use cache controls, and send completed async jobs back through webhooks.
Mon
Wed
Today
Give vision models the pixels and the page context.
Return a base64 image together with markdown, HTML, plain text, or metadata in one response.
Turn live pages into durable output.
Create full-page images or PDFs for research, audit trails, reports, and repeatable evidence workflows.
Generate consistent website visuals on demand.
Use fixed viewports and formats to create thumbnails, previews, or open graph images from HTML.
OG image generationHow it works
From request to cached artifact in a few predictable steps.
The browser pool renders the page once, applies capture options, stores the output when needed, and serves repeat requests from cache.
1
Request
URL, HTML, and render options.
2
Render
Browser pool loads and prepares the page.
3
Capture
Image, PDF, diff, or JSON payload.
4
Return
Stream, store, cache, or webhook.
Build or call
Keep control of the workflow, without owning every moving part.
A self-managed browser can take a screenshot. SnapshotFlow packages the surrounding work into the same API surface.
