string.is

Self-Hosted

Self-hosted string manipulation and utility toolbox

Overview

string.is is an open-source, self-hosted web app for all string-related tasks—encode/decode (Base64, URL, JSON), hash (MD5, SHA-1/256, bcrypt), format (JSON pretty-print, CSV to JSON), and validate (emails, URLs, IPs). Deploy via Docker for quick setup, or run from source using Node.js. It’s lightweight (no database required), lets you handle sensitive data locally, and avoids relying on third-party APIs for privacy and security.
