2024 in Review: Understanding Complex Systems at Scale

2024 in Review: Understanding Complex Systems at Scale

Anyone who's worked on a non-trivial codebase knows the feeling: you open your editor to make what seems like a straightforward change, only to find yourself an hour later deep in a maze of interconnected services, trying to understand how everything fits together. This challenge of understanding complex systems has been at the heart of our journey in 2024.

Growth and Impact

This year marked significant growth in our mission to make system understanding more accessible:

  • Our platform now analyzes over 25 repositories across multiple engineering teams
  • We've mapped over 1.5 million code component versions and 10 million code element versions
  • Our monthly active users peaked at 20 developers actively using the platform
  • We reached $500 in monthly recurring revenue from teams investing in better system understanding

These numbers tell a story of growing adoption, but more importantly, they validate the need for better tools to understand complex systems.

Key Insights from 2024

  1. Beyond Documentation
    Our initial focus on automated documentation evolved when we saw how developers actually explore and understand their systems. Active exploration and safe experimentation proved more valuable than static documentation.
  2. Visualization Complexity
    Our work with graph visualization revealed a fundamental challenge in representing complex systems. Even moderate-sized applications require sophisticated approaches to progressive discovery and exploration.
  3. Workflow Integration
    Engineers maintain highly efficient IDE workflows. The most effective tools enhance these existing patterns rather than disrupting them.
  4. Navigation Patterns
    File-based navigation remains fundamental to how developers understand systems. Modern tools need to augment these established patterns.
  5. Core Questions
    Developers prioritize understanding what they can safely change and which dependencies might be affected by their modifications.

Our Journey

Initial Approach: Documentation Generation

We began 2024 developing automated documentation tools to capture how systems were built, architectural decisions, and their outcomes. Our vision centered on self-updating documentation that would evolve with the system.

Evolution: System Visualization

Working directly with development teams revealed a deeper need. Engineers needed to understand the complex relationships in their microservice architectures. This insight led us to develop visualization tools powered by static analysis and graph theory.

Current Direction: Enhanced Developer Workflows

Adding file-based exploration to complement graph visualization marked a breakthrough. Direct code citations in design documents drove significant engagement. These successes reinforced the importance of working within existing developer workflows.

Effective Approaches

Our most successful features aligned naturally with how developers work:

  • Direct code citations in documentation
  • File-based system exploration
  • Progressive complexity revelation
  • Integration with existing workflows

Looking Forward: Our 2025 Roadmap

For 2025, we're embarking on three key initiatives to enhance system understanding capabilities:

Performance Optimization

We recognize that analysis speed directly impacts developer workflow. Our engineering team is prioritizing the core analysis engine to reduce initial analysis and update times. While our incremental analysis capability provides a strong foundation, we're investing in further optimizations to eliminate processing delays that currently affect larger codebases.

Enhanced System Exploration

Our next generation of visualization tools will focus on progressive discovery. We're revamping the graph visualization interface to provide contextual information at each exploration step, making system relationships more intuitive to navigate. A new side panel will offer detailed component information while maintaining focus on the relevant system context.

Seamless Developer Integration

We're developing a VS Code extension to bridge the gap between code exploration and system understanding. This integration enables developers to move naturally from examining specific code to understanding its broader system context. By automatically identifying key system components like service endpoints, UI components, and integration points, we're creating clear entry points for system exploration.

The result will be a fluid workflow where developers can:

  1. Discover relevant code through their familiar IDE environment
  2. Seamlessly transition to system-level exploration
  3. Progressively understand component relationships and dependencies
  4. Make informed decisions about potential changes

While we're excited about future possibilities with AI-enhanced impact analysis, our immediate focus is on delivering these foundational improvements that will provide immediate value to development teams.

Community Engagement

The insights and feedback from our early adopters have shaped every aspect of our platform. We've learned alongside our users, and their perspectives continue to guide our development.

We invite you to share your experiences:

  • How do you currently approach understanding complex systems?
  • What are your biggest pain points in navigating microservice architectures?
  • What development workflows would you never want to give up?

Interested in these approaches to system understanding? We're always looking for developers to try out new tools and share their perspectives. Reach out to learn more.
