Guide and privacy
Check the input
UUID generation requires browser crypto support. If unavailable, the tool reports the missing capability.
Local execution
The free tool uses browser processing when supported and keeps entered snippets out of product APIs.
Review method
Each utility exposes a focused transformation, visible limits and a short result that can be copied or inspected before any paid feature exists.
Limits
The free browser surface is designed for snippets and small files. Saved team areas, batch jobs, larger files and API automation are follow-on account options.

FAQ
Are snippets stored?
No. DevUtility Lab does not use account storage, localStorage, sessionStorage or a product API in the free tool.
Can I paste production secrets?
Avoid pasting secrets. The tool processes locally, but safe handling still means redacting keys, tokens and confidential data.
