## What it is
A web-based collection of encoding and parsing tools, including Base64/URL encoding, diff viewing, and compiler-theory utilities that convert regexes to NFA/DFA and build LL/LR parsing tables. It is a static site built from JavaScript and hosted on GitHub Pages.

## Use cases
- convert regex to NFA and DFA
- build LL(1) or LALR parsing tables for a grammar
- encode and decode base64 or URL strings online
- eliminate left recursion in a context-free grammar
- compute first and follow sets
- compare two texts with a diff viewer
- emulate MIX assembly language programs

## When to choose
- you need quick online tools for encoding/decoding tasks
- you are studying compiler theory and want to visualize automata and parsing tables
- you want to convert regexes to minimal DFAs without installing anything

## When to avoid
- you need a programmable parsing library to embed in your own code
- you require production-grade encoding with streaming or large-file support
- you need tools beyond the fixed set provided

## Facets
- artifact type: application
- maturity: active
- function: parser, serialization, developer-tools, gui
- domain: developer-tools, parsers, education, web-development
- platform: browser
- tags: compiler-theory, regex-to-automata, grammar-parsing, online-tools, encoding-decoding, web-server, javascript, nodejs
