A workshop for words, built by one person.
Snapastr is a privacy-first toolbox for everyday text work — converting case, encoding and decoding, formatting JSON, decoding tokens, hashing, slugging and a few fun extras. Every tool runs entirely in your browser.
Who makes it
Snapastr was founded in 2024 by Jack Lumman, a 26-year-old software developer from Finland. Jack built Snapastr after one too many times pasting sensitive text into ad-heavy online utilities that quietly upload everything you type.
Snapastr is the deliberate opposite: fast, clean, free for personal use, and built so your text never leaves your machine.
The principle
“If a tool can run in your browser, it should — and your data should never touch a server it doesn't need to.”
