Frequently Asked Questions
Everything you might want to know about DevKit Labs — how it works and how your data stays private.
What is DevKit Labs?
DevKit Labs is a free collection of fast, privacy-friendly developer and everyday utilities — formatters, converters, encoders, generators and more. Every tool runs entirely in your browser.
Is DevKit Labs free to use?
Yes. Every tool is completely free, with no usage limits and no sign-up required.
Do I need to create an account?
No. There are no accounts, logins or paywalls — just open a tool and use it.
Is my data private? Does anything get uploaded?
Your data stays on your device. Every tool processes your input locally in your browser using JavaScript, so what you paste — API responses, config files, passwords, tokens — is never sent to or stored on a server.
Do the tools work offline?
Once a page has loaded, the tools run without a network connection because all processing happens in your browser. The site is also installable as a progressive web app (PWA).
Do you track or log what I enter?
No. The content you enter into a tool is never transmitted, logged or tracked. Nothing you paste leaves your browser.
Can I use these tools on my phone?
Yes. The site is fully responsive and works on phones, tablets and desktops, and can be added to your home screen as an app.
Why does everything run in the browser instead of on a server?
Client-side processing is more private (your data never leaves your device), faster (no round trip to a server) and works offline. It's the core design principle of every tool here.
Which tools are available?
There are tools for converting data formats, encoding and decoding, formatting and validating code, generating IDs, passwords, QR codes and mock data, and a range of text utilities. Browse the full list from the sidebar or the home page.
