What is IsAgent?
As AI agents become common visitors to your web applications, you need a simple way to tailor their experience. IsAgent is a lightweight React SDK, built by Stytch, that empowers you to reliably detect AI agents versus human users. This allows you to serve custom content and create optimized, distinct interactions for each type of visitor.
Key Features
✨ Effortless Conditional Rendering Implement agent-specific views with declarative React components. Simply wrap your content in <IsAgent> or <IsHuman> tags to control exactly what renders for each audience, making your code clean and your intent clear.
⚙️ Flexible Hook-Based Control For more complex logic, use the useIsAgent hook to access the detection state directly. This gives you the granular control to build custom components, trigger side effects, or manage application state based on whether the visitor is an agent or a human.
🚀 Lightweight and Zero-Config IsAgent is built with minimal dependencies for a negligible impact on your application's performance. With a zero-configuration setup, you can install the SDK and get started in minutes—no complex setup required.
🧩 Works Beyond React While optimized for React, IsAgent's core logic is accessible through a low-level isAgent() function. This allows you to integrate AI agent detection into any JavaScript or TypeScript project, giving you flexibility across your entire tech stack.
How IsAgent Solves Your Problems:
Optimize Content for AI: Serve a simplified, data-rich HTML version of your page to AI agents for better indexing and analysis, while preserving the dynamic, interactive experience for your human users.
Improve Resource Management: Prevent AI agents from loading resource-intensive components like complex charts, interactive demos, or third-party widgets. This saves your bandwidth and their processing time, creating a more efficient experience for everyone.
Enhance Analytics and Insights: Segment your user analytics to understand how much of your traffic comes from AI agents versus humans. Gain clearer insights into user behavior by separating bot activity from genuine human engagement.
Unique Advantages
IsAgent is designed with a specific philosophy that sets it apart from general-purpose bot blockers.
Focused on Experience, Not Just Blocking: While many tools focus on blocking traffic, IsAgent is designed to help you build a better Agent Experience (AX). Instead of putting up a wall, it gives you the tools to guide agents toward the content most useful for them, much like ARIA attributes provide accessibility for screen readers.
A Lightweight "Client Hint": Unlike heavy security scripts that can impact performance, IsAgent is a minimal, frontend-first SDK. It provides a clear "client hint" about the user type without the overhead of a full-blown fraud prevention system, ensuring your site remains fast and responsive.
Transparent and Developer-First: Built by the team at Stytch, IsAgent is designed for developers. With clear documentation, simple components, and a low-level API, it integrates seamlessly into your workflow, empowering you to build, not block.
Conclusion:
IsAgent gives you the control to build smarter, more responsive web applications that cater to all visitors—human or AI. By distinguishing between these audiences, you can optimize performance, improve data quality, and deliver a superior experience for everyone.
