act101 - the definitive codebase quality and refactoring tool for agents

About act101

act101 empowers engineers to refactor and port code across 163 languages with precision. It’s designed for individual developers and teams who want to ensure their AI coding agents produce reliable, tested changes without guesswork. By analyzing code, executing refactors, and providing deterministic merge verdicts, act101 transforms the coding process into a structured and verifiable workflow. The platform operates in three stages: Analyze, Act, and Attest. First, it analyzes the codebase with 41 analyzers to identify potential issues. Then, it applies one of 183 refactor operations, ensuring changes are made efficiently. Finally, it attests to the changes with a clear verdict and rollback options, allowing developers to maintain control over their code quality. With act101, you can trust that every modification is backed by thorough analysis and testing.

Overview

Who is it for?

Individual engineers and codebase owners seeking reliable AI refactoring.

Problem

Developers often struggle with the uncertainty of AI-generated code changes, leading to potential bugs and regressions. act101 addresses this by providing a structured approach to refactoring and porting code, ensuring that every change is verified and tested.

Solution

act101 uses a three-stage process: Analyze, Act, and Attest. It analyzes the codebase to identify issues, applies refactor operations, and provides a deterministic verdict on the changes. This ensures that developers can trust the modifications made by their AI agents, reducing the risk of introducing errors.

What makes it unique

Unlike other tools, act101 offers a closed-loop system where every change is analyzed, executed, and verified. It provides a clear verdict on code changes, allowing developers to maintain high code quality and trust in AI-generated modifications.
