FAQ
Frequently Asked Questions
Are these tools really free?
Yes, every tool on WhatsMyTools is completely free with no paywalls, premium tiers, or account requirements. We believe utility tools should be accessible to everyone.
Is my data private?
Most tools run entirely in your browser — no data is sent to any server. A few tools (like IP lookup and DNS checks) require a server request to function, but we never store your data or track your usage beyond basic anonymized analytics.
Do I need to create an account?
No. Every tool works instantly without signup, login, or any personal information. Just open a tool and use it.
What browsers are supported?
WhatsMyTools works in all modern browsers including Chrome, Firefox, Safari, Edge, and Brave. Some tools require specific browser APIs (like the EyeDropper API for the color picker) and will show a compatibility note if your browser doesn't support them.
How accurate are the results?
Our tools read data directly from your browser and device APIs, so results are as accurate as your browser reports. For network tools that query external services, results reflect real-time data from those services.
Can I use these tools on mobile?
Yes, all tools are fully responsive and work on phones and tablets. Some hardware-specific tools (like keyboard tester) work best on desktop, but will still load on mobile.
Can I embed these tools on my own website?
Yes — every tool is embeddable for free. Open any tool page, scroll to the "Add this tool to your site" section, and copy the one-line snippet. The tool renders right on your page, resizes itself automatically, and supports light, dark, and auto themes.
