Frequently Asked Questions
Is DevPad really free?
Yes. All 25 developer tools are completely free with no usage limits. There are no hidden fees, no premium tiers, and no feature gates.
Is my data safe?
Your data never leaves your browser. All processing happens client-side using native browser APIs. Nothing is sent to any server, including ours.
Can I use DevPad on my phone?
Yes. DevPad is fully responsive and works on any device with a modern browser. You can also install it as a Progressive Web App for quick access.
How is DevPad different from other tool sites?
Most developer tool sites run ads, track your data, or require accounts. DevPad is open, private, and fast. Every tool is a dedicated page with proper documentation, not a cramped widget buried in ads.
