Is Aruvix free to use?

Yes, Aruvix is completely free. We don't require an account, a credit card, or a subscription.

Does Aruvix send my data to a server?

No. The vast majority of our tools, including formatting, conversion, and validation, process data entirely in your browser using local resources.

Who is Aruvix for?

It is designed for developers, QA engineers, data scientists, and anyone working with APIs, structured data formats, and frontend web development.

Do I need an account?

No. I built Aruvix so you can open a tool, paste the data you are working on, get the result, and leave without sign-up friction.

What happens when I use the API Client?

API Client requests are sent only when you press send, and only to the endpoint you choose. Formatting and inspection around the response stay inside the Aruvix workflow.

Can Aruvix replace desktop developer tools?

For quick formatting, conversion, API checks, QA helpers, and frontend utilities, yes. For team sync, collections, or enterprise workflows, pair it with your existing stack.

Are there limits with browser-local tools?

The practical limit is your browser and device memory. Large payloads can still work, but very heavy files may be slower than a native desktop workflow.

How can I report a bug or request a feature?

Send feedback through the About page contact details. Clear examples, sample input, expected output, and browser details help me fix issues faster.
