Free developer tools compared. Why use 10 different sites when SlapMyWeb gives you JWT decoder, JSON formatter, Base64, hashing, regex, and more — all in one place?
JWT.io does one thing: decode JWTs. SlapMyWeb gives you JWT decoder, JSON formatter, Base64, URL encoder, Hash generator, Regex tester, and 14+ more developer tools — all on one site.
Stop switching between JWT.io, jsonformatter.org, base64decode.org, and regex101. SlapMyWeb puts every tool you need in a single, consistent interface.
SlapMyWeb is built for developers who live in dark mode. Every tool has syntax highlighting, keyboard shortcuts, and a clean interface — no ads, no clutter.
Like JWT.io, all SlapMyWeb developer tools run entirely in your browser. Your tokens, data, and code never touch a server.
JWT.io is great at what it does — decoding JWTs. But as a developer, you need more than one tool. SlapMyWeb replaces your entire bookmark bar of developer utilities with a single, modern, ad-free interface. Same privacy, 20x the functionality.
