## What it is
FeHelper is an all-in-one browser extension toolbox for Chrome, Firefox, and Edge (Manifest V3) that bundles 30+ developer utilities such as JSON formatting and diffing, encoding/decoding, timestamp conversion, QR code generation, code beautification, API debugging, and an AI assistant. It has been continuously maintained since 2012 and lets users enable, reorder, and configure tools on demand.

## Use cases
- format and beautify json responses in the browser
- decode base64 url jwt and gzip strings
- convert unix timestamps to dates
- generate and decode qr codes
- debug http requests like a lightweight postman
- test websocket connections
- convert excel csv to json
- generate mock test data

## When to choose
- you want many small web dev utilities in one extension instead of separate websites
- you frequently inspect, format, or diff JSON during API development
- you need quick encoding, timestamp, or QR code conversions while browsing
- you use Chrome, Edge, or Firefox and want a maintained multi-tool extension

## When to avoid
- you need a dedicated, deeply featured tool for a single task like full API testing or screenshot capture
- you cannot install browser extensions in your environment
- you need server-side or CLI batch processing rather than in-browser helpers
