JsRpc is a Go-based RPC server that lets you remotely invoke JavaScript methods running in a browser via WebSocket, avoiding the need to extract and re-implement obfuscated code. It is commonly used in JavaScript reverse engineering to fetch computed values such as encryption or decryption results directly from a live page.

Use cases

• remotely call browser javascript functions via rpc
• get encryption results from a website without reversing the js
• execute js code in a browser through an http api
• fetch page cookies and html from an injected browser session
• avoid patching javascript environments when reverse engineering
• bridge websocket communication between browser console and server

When to choose

• you need values computed by a site's own javascript (e.g. encrypted params) without reimplementing the algorithm
• you want to drive a real browser session's js from external scripts or crawlers
• you are doing js reverse engineering and want to skip environment emulation

When to avoid

• you need a general-purpose headless browser automation tool like Playwright or Selenium
• you want a production-grade distributed rpc framework
• your use case does not involve a live browser executing javascript
