Refraction

Refraction is presented as a code generation tool for developers. Users paste a block of code, choose a language or framework, and click Generate. The site lists features covering code improvement (bug detection, refactoring, style checks, adding types, separating hardcoded literals), code writing (creating functions, generating SQL queries, regexes, CI/CD pipelines, CSPs, diagrams with Mermaid), code understanding (explaining code, adding documentation and debug statements, learning programming concepts), and code conversion (between languages and CSS frameworks). It also lists unit test generation for a chosen framework. The site states support for 56 languages, offers extensions for VS Code, Sublime Text, JetBrains, Visual Studio, GitHub Autoreview, and Terminal, and reports 13.7K+ developers, 65.1K+ code generations, and 2.9M+ lines of code generated. A free sign-up is mentioned, and a pricing page is linked.
