Frequently Asked Questions
Everything you need to know about our browser execution model.
Is Urban Mixo truly free?
Yes, 100%. Every utility on Urban Mixo is free to use with no subscription plans, paid tiers, or account registrations. Tools run directly in your browser, eliminating expensive server-side processing costs.
Are my files or text inputs uploaded to your servers?
No. Urban Mixo utilizes client-side Web APIs, Web Crypto, and JavaScript. All calculations and text processing occur entirely in your local browser sandbox. Nothing is transmitted to our backend.
Do I need an account or API key?
No registration or API key is required. Simply open the tool you need, input your data, and get instant results.
Can Urban Mixo work offline?
Yes. Once the page is loaded, the client-side JavaScript is cached locally in your browser. You can disconnect your network connection and continue processing text and calculations without interruption.
Are there file or character size restrictions?
Because there are no server upload limits, constraints are defined solely by your device's available memory (RAM). Standard desktop and mobile browsers can easily handle several megabytes of text and JSON without lagging.
