Background
Good architecture makes software scalable, maintainable, and understandable. It’s essential from day one—not just for big enterprises.
Architecture erodes over time
Section titled “Architecture erodes over time”Erosion in regards to software architecture is a gradual process that can lead to an inefficient maintenance burden. It’s hard to maintain and not flexible. Studies show developers spend up to 70% of their time just understanding existing code.
Usually the amount of technical debts rises over the years. Without architecture guidance the structure of a codebase can become like spaghetti which is hard to maintain and barely flexible.

This erosion reduced the productivity and increases the costs per line of code. Less code can be developed and hence less features can be added.

TangleGuard stops the erosion
Section titled “TangleGuard stops the erosion”TangleGuard stops architectural erosion and reduced the risk of having a tangled code structure before it becomes hard to maintain:
- Define clear architectural boundaries
 - Enforce them automatically in CI/CD
 - Catch violations immediately—not months later
 - Keep maintenance costs low from day one
 
Think of it as lightweight architecture governance—modern, focused on code structure, not implementation details.
Architecture shouldn’t live in slide decks. It should live in your pipeline, protecting your codebase as it grows.
