What does Zatanna do?

Zatanna maps human-only software workflows and exposes them as reliable APIs. Instead of building brittle browser automation scripts, you show the task once and Zatanna reconstructs the underlying request flow into a stable endpoint your AI agents and internal tools can call in production.

How is Zatanna different from web scraping or RPA?

Traditional web scraping replays clicks and waits on page elements, which breaks whenever the UI changes. RPA tools automate screen-level interactions but require constant maintenance. Zatanna reconstructs the actual HTTP request behavior behind a workflow, producing a stable API that doesn't depend on the UI layer at all.

How does Zatanna handle anti-bot detection?

Zatanna manages TLS fingerprinting, proxy rotation, and detection-sensitive request behavior below the API layer. Sessions, cookies, retries, re-authentication, and error recovery are all handled automatically so your integration stays reliable.

What types of workflows does Zatanna support?

Zatanna works best for workflows that are important, repetitive, and stuck behind a UI — including back-office systems with no API, document and record workflows involving uploads, claim forms, and status checks, and AI agent actions in external third-party software.

How do I integrate with Zatanna?

Integration is a three-step process: (1) A human runs the workflow once while Zatanna observes the real behavior, (2) Zatanna builds a request model that reconstructs the calls, state transitions, and recovery logic, (3) Your systems call a single stable API endpoint while Zatanna manages the fragile workflow underneath.

Browser Fingerprinting: How Websites Detect Automation

Browser fingerprinting uses canvas, WebGL, fonts, and JavaScript environment probes to detect headless browsers and automation tools.

TL;DR

Browser fingerprinting uses canvas, WebGL, fonts, and JavaScript environment probes to detect headless browsers and automation tools. This matters for anyone building production web automation, AI agent integrations, or workflow APIs that interact with external systems.

Why this matters

Web automation in production requires understanding the technical landscape. Browser Fingerprinting is a critical concept that affects reliability, detectability, and maintenance cost. Teams that ignore it end up with fragile scripts that work in development but fail in production.

How it works

Browser fingerprinting uses canvas, WebGL, fonts, and JavaScript environment probes to detect headless browsers and automation tools. The technical implementation involves multiple layers of complexity that interact with each other in ways that aren't always obvious.

Understanding these mechanics helps engineering teams make better decisions about their automation architecture — whether to use browser-level automation, request-level automation, or a hybrid approach.

Practical implications

For teams building production automation:

Architecture decisions — understanding browser fingerprinting helps you choose the right automation approach from the start
Debugging failures — when automation breaks, knowing the underlying mechanics helps you diagnose the root cause faster
Vendor evaluation — when evaluating automation tools, understanding these concepts helps you ask the right questions

How Zatanna handles this

Zatanna's workflow API platform manages browser fingerprinting as part of its reliability layer. Instead of exposing this complexity to your engineering team, it's handled automatically below the API surface. Your systems call a stable endpoint while Zatanna manages the technical details underneath.

This means your team can focus on building product features instead of becoming experts in browser fingerprinting.
