About
EdgeComet is an open source middleware solution designed to make JavaScript-heavy websites fully visible to search engines and AI crawlers by rendering dynamic content into static HTML that bots can understand. It sits behind a reverse proxy and selectively intercepts bot traffic, executing JavaScript through a headless Chrome rendering service and delivering fully rendered pages instead of empty client-side shells. This approach addresses the core limitation where crawlers cannot execute JavaScript, leaving content from frameworks like React, Vue, or Angular effectively invisible. EdgeComet works through a three-step pipeline, rendering dynamic pages, caching the generated HTML for fast reuse, and scaling delivery through a distributed architecture with millisecond response times. It includes advanced bot detection with over 20 predefined crawler patterns, flexible routing rules, and device-specific rendering for mobile or desktop indexing.

About
Cutting-edge JavaScript obfuscation techniques with control-flow flattening, tamper detection and other in-app protection transforms. We would not send our own unprotected code to a remote service controlled by third parties and we would not expect you to either. JSDefender supports major JavaScript frameworks, runtimes, and bundlers including Angular, Node, React, React Native, Webpack and others. Unlike languages like .NET and Java that are compiled to intermediate, stack-based assembly instructions before being distributed in binary form, JavaScript apps are typically distributed in source form. This means that your code is directly visible to anyone with access to the execution environment (like a browser). So, potential attackers can very easily step through the running code using a debugger built into their browser, or use other tools to statically analyze the code for vulnerabilities.
