Engineering Series: Anti-Botting (3/3)

Browser fingerprinting has become one of the most powerful tools in modern anti-bot systems. This post breaks down the fingerprinting toolkit websites use to distinguish real users from automation, covering the signals collected, how they're combined, and why they remain effective even when traditional detection methods fail.

Engineering Series: Anti-Botting (2/3)

Modern anti-bot systems don't just look at where traffic comes from. They also inspect what happens inside the browser itself. This post explores challenge scripts, the JavaScript code websites use to collect browser fingerprints and behavioral signals. We break down how these scripts work and why they play a central role in distinguishing real users from automation.

Engineering Series: Anti-Botting (1/3)

Most people think anti-bot systems start and end with CAPTCHAs. In reality, websites detect automation across multiple layers. In this first post, we break down the three core layers of anti-botting: network fingerprints, browser fingerprints, and application-level behavioral signals. Understanding these layers is critical for building reliable AI agents that operate on the web.

StableBrowse is a new browser layer for AI agents. They enable agents to navigate the web with 70% fewer tokens and 3-4x faster execution.

Congrats on the launch, @deepitshah5, @JayMehta446970, @_sarthak____, and @somanshshah!

Our first engineering blog is out: Knowledge Graphs.

At StableBrowse, we’re researching how websites can be represented as executable knowledge graphs for AI agents.

The post explores concepts like navigation, extraction and interaction as the three core browser primitives, along with problems such as topological blindness and state explosion in modern browser agents.

We also discuss how structured execution graphs can encode states, actions, workflows and underlying APIs into reusable representations for agents.
