Undebt is a Python-based command-line tool for performing massive, automated code refactoring across an entire codebase. Users define find-and-replace rules as pattern files with a grammar and replace function, which Undebt applies to source files.

Use cases

• refactor millions of lines of code automatically
• convert old-style Python classes to new-style classes
• apply complex find-and-replace rules across a codebase
• automate repetitive code migrations
• rewrite deprecated API usages project-wide

When to choose

• you need to apply a consistent, complex transformation across a large codebase
• you want to define rewrite rules in plain Python rather than regex
• you are doing one-off large-scale code migrations

When to avoid

• you need simple regex find-and-replace that your editor already handles
• you need actively maintained tooling with recent updates
• you need language-agnostic refactoring with official support for non-Python languages
