About JavaScript Dev Tools
JSTools.Space is a free, privacy-first platform containing focused utilities for common development tasks. It helps developers format and validate JSON, HTML, CSS, XML, and Markdown; encode Base64 and URLs; inspect JWTs; generate passwords, API keys, UUIDs, hashes, salts, nonces, TOTP secrets, and other authentication values; compare text; query structured data; and prototype HTML, CSS, and JavaScript.
Most processing happens directly inside the browser, so users do not need to upload code, credentials, tokens, or test data to an application server. No account or project setup is required.
The platform also includes a configurable Dummy Data Library, practical documentation, a developer security blog, the JSTools JSON Inspector Chrome extension, and the cross-platform JSON Studio desktop application.

Really enjoying JavaScript Dev Tools
Free Online Developer Tools Hub | JSTools.Space: Privacy-first developer utilities for formatting JSON, encoding Base64, generating secure tokens, com. I've been using this for a bit and really appreciate how well it's put together. The interface is clean and it does exactly what it promises. Nice work by the team.
