About Refactron
A safety-first refactoring engine for evolving real-world codebases.
The Problem
Most production codebases carry significant technical debt, but refactoring them is often avoided.
- Manual refactoring is slow, expensive, and risky
- Automated tools focus on generation without guaranteeing correctness
- Teams postpone structural improvements, making codebases harder to maintain

Our Approach
Refactoring as a structured engineering process, not a one-shot automation problem.
- Analyzes code structure and identifies targeted improvements
- Proposes incremental refactors that preserve existing behavior
- Makes refactoring predictable, reviewable, and safe
What Safe Means
Safety is not a claim—it's a set of constraints Refactron is built around.

Human-in-the-loop refactoring
Every change requires explicit approval from developers
analyze.sh
$ refactron analyze src/
✔ Scanned 142 files
✔ Detected 37 refactoring opportunities
✔ High-risk changes: 0
✔ No code changes applied
refactor.sh
$ refactron refactor src/
→ Extract duplicated logic in auth/utils.py
→ Simplify nested conditionals in payments/service.py
✔ Suggestions generated
✔ No changes applied
autofix.sh
$ refactron autofix --safe
✔ Applied 12 low-risk refactors
✔ Behavior preserved
✔ Changes staged for review
$ refactron metrics
✔ Complexity reduced: 18%
✔ Duplication reduced: 22%
incremental.sh
$ refactron autofix --safe
✔ Applied 12 incremental refactors
✔ Files modified: 7
✔ Large rewrites avoided
rollback.sh
$ refactron report
✔ Generated refactor-report.md
✔ Included rationale and before/after diffs
$ refactron rollback
✔ All changes reverted successfully
