act101

act101 is a code quality layer for AI-assisted development. It is built to analyze changes made by coding agents, apply refactors, and attest to the result before a merge happens. The homepage positions it as a way to close the loop on quality when AI agents write code faster than teams can maintain it.

The product is centered on three stages: Analyze, Act, and Attest. Analyze includes 41 analyzers that look for issues such as dead code, cycles, coupling, hotspots, and seams before changes are made. Act provides 183 refactors, including operations like rename, extract, inline, move, and modernize. Attest adds verification and a deterministic gate that can return MERGE, REVIEW, or BLOCK along with a signed receipt and rollback support.

The tool is aimed at individual engineers, codebase owners, architects, and people who want their AI to code better without getting into technical details. It is presented as a native binary with no dependencies and no supply chain risk, and it can be connected to local agentic coding platforms. The site lists support for Claude Code, Cursor, Codex, Windsurf, Zed, and opencode, and shows command-line workflows for installing and registering the tool.

act101 Online is a separate GitHub-native health scanner for AI-authored code. It produces an AI-Code Health Score with Security and Architecture components and publishes results as a PR comment, a Check Run, and a SARIF upload for code-scanning alerts. The pricing section also shows plans for personal, commercial, and architectural use, with a free Builder Edition and paid tiers for Engineering, Architecture, and Elite.
