FizzBee – Model Your Distributed System Before You Build It

Build confidence in your design before you write a single line of code. FizzBee is a software modeling tool that helps distributed systems developers design, visualize, and verify their systems early. Write your system behavior in simple, Python-like pseudocode and let FizzBee uncover issues, generate diagrams, and even predict performance – all before you start coding.

Why Model Your System?

Design docs and diagrams are useful, but they can’t catch every hidden flaw. Modeling with FizzBee lets you:

  • Explore Edge Cases: Automatically simulate complex scenarios and failures.
  • Eliminate Ambiguity: Use an executable design spec that everyone can understand.
  • Catch Bugs Early: Identify design issues before they become costly problems.
  • Iterate with Confidence: Quickly refine your architecture with immediate feedback.

Key Features

  • Ease of Use: Write models in a familiar Python-like syntax and start verifying your design in minutes.
  • Expressiveness: Capture complex distributed behaviors with high-level constructs like roles, message channels, and fault injection.
  • Visualization: Automatically generate clear diagrams that illustrate system states and interactions.
  • Autonomous Testing (Upcoming): Auto-generate model-based tests to ensure your implementation aligns with your design.
  • Performance Modeling: Simulate performance metrics such as latency and throughput to validate your system’s scalability.

How It Works

  1. Define Your System: Describe your components and interactions in FizzBee’s intuitive modeling language.
  2. Run the Analysis: Let FizzBee explore all possible scenarios and event orderings, including failures and race conditions.
  3. Review the Results: Get instant feedback through reports and visual diagrams that highlight issues.
  4. Refine and Repeat: Tweak your model and re-run the analysis until your design meets all requirements.
