FeHelper
FeHelper is a web browser extension toolbox and frontend development toolkit integrated into Chrome, Firefox, and Edge. It serves as a data transformation utility, a web page debugging tool, and an AI-powered coding assistant.
The project distinguishes itself by integrating local models and OpenAI-compatible APIs to write, refactor, and repair code directly within the browser. It also provides capabilities for generating TypeScript schemas and Zod definitions from data samples using AI.
The toolkit covers a broad range of developer utilities, including network debugging for HTTP and WebSocket connections, data encoding and decoding for formats like JWT and Base64, and JSON processing tools for formatting, repairing, and comparing structures. It also includes frontend tools for page layout measurement, source code formatting, and custom user script injection.
Additional capabilities include a variety of media and document tools for Markdown editing, QR code processing, and image conversion, alongside utility generators for unique identifiers and secure passwords.
