About UUID Studio
UUID Studio is a collection of free developer tools built for everyday engineering work: converting UUIDs, formatting JSON, decoding JWTs, generating hashes, testing regex, parsing cron expressions, and more.
Why we built it
Developers constantly context-switch between single-purpose sites. UUID Studio brings common utilities together with a consistent UI-each tool also has its own focused page so you can bookmark or share exactly what you need.
Privacy-first by design
Most tools run entirely in your browser. We do not ask you to create an account to convert a UUID or pretty-print JSON. That local-first model is a core product principle-not an afterthought.
Who it’s for
- Backend and API engineers working with identifiers and payloads
- DevOps and SREs inspecting tokens, headers, and timestamps
- Students and learners experimenting with formats and crypto primitives
- Anyone who needs a fast utility without installing software
Workbench
The Workbench combines Convert, Compare, JSON, and Crypto modes in one tabbed interface-ideal when you are jumping between related tasks.
