How It Works
Static analysis, human judgment
Unfault analyzes patterns with a Rust engine, but you remain fully in control. It simply helps reveal better paths when they matter most.
Analyze Code
Unfault parses your codebase using tree-sitter and builds a semantic model to identify patterns that commonly cause issues in production systems.
Find Patterns
It detects runtime hazards like unbounded operations and missing timeouts, plus architectural issues like entangled responsibilities that hurt maintainability.
You Decide
Unfault provides suggestions with reasoning and auto-fix patches, but you're always in control. Apply fixes with one click, or tweak them to fit your context.
Under the hood
Built for speed and precision
Rust Engine
The core analysis engine is written in Rust for performance and safety. Average scan time under 300ms, even for large codebases.
Tree-sitter Parsing
We use tree-sitter for accurate parsing across 15+ languages. This gives us a full AST to analyze patterns correctly.
Auto-fix Patches
Every finding includes ready-to-apply patches. Review the diff, understand the reasoning, and apply with one click.
CLI & API
Run from the command line, integrate with CI/CD, or use as an AI agent tool. The same engine powers all interfaces.
Philosophy
Built on conviction
Unfault reflects beliefs that matter for building software
AI can write code, judgment still matters
Language models are powerful at generating code, but understanding context, tradeoffs, and long-term implications requires human judgment.
Code is already operational
Every line of code you write will eventually run in production. Unfault helps surface issues before they become real problems.
Discernment over automation
We don't believe in perfect automation or zero-touch solutions. Good engineering requires thoughtfulness and careful consideration.
Clarity prevents future pain
Code that is clear and follows steady patterns is easier to maintain, debug, and extend. Unfault nudges toward this kind of code.
Tools should support flow, not meter it
Unfault integrates into your workflow without getting in the way. It's designed to help you think better, not slow you down.
"Show maturity, not magic"
This is not evangelism. It's companionship.
