About Callgraph.io
Our mission is to make reading code as intuitive as reading a blog.
Built for learning Database internals and High Performance system softwares
Building systems software—the databases and caches that power the world—is one of the most rewarding paths a software engineer can take. This is the "bleeding edge," where performance is paramount and elegant data structures and algorithms like B+Trees, Radix Trees, and Raft are the standard.
But the barrier to entry is high. Navigating massive codebases written in C, C++, or Rust can be daunting for even the most seasoned developers. Callgraph.io is designed to bridge that gap. While mastering systems engineering takes years of dedication, we provide the map you need for your initial journey, helping you visualize and navigate the complex codebases you’re ready to master.
How it Works
Callgraph.io employs dynamic analysis to map function relationships by executing software through various logic flows. By capturing these real-time dependencies and presenting them via modern visualizations, it provides developers with an intuitive, high-level map for navigating complex codebases.
Interactive Visualization
Navigate through function calls seamlessly. Our interactive graph allows you to expand and collapse nodes, revealing the logic layer by layer. Focus on what matters and filter out the noise.
AI Explanations
Don't just see the code; understand it. Click any function in the call graph for an instant AI-powered definition and a deep-dive explanation of its purpose, inputs, and outputs along with a code walkthrough.
Inverted Index
Find out who calls whom effortlessly. Select a function to reveal its callers and seamlessly jump between every location where it is invoked across the codebase.
Process Fork Tracking
Debugging multi-process applications is notoriously hard. We make it easy by letting you seamlessly navigate between parent and child process call stacks during fork events.
Integrated Code Browser
Context is king. Instantly view the source code of any function with our built-in high-performance code browser, complete with syntax highlighting and line numbers.
Private Project Onboarding
Your code is your intellectual property. We provide secure onboarding for private and proprietary projects so you can analyze your internal tools with the same power as open-source libraries.
