designtool.tools is a free online design toolkit offering color palettes, gradients, contrast checking, color wheels, and more — all in 14 languages.
Built by a solo developer, this site focuses on making design tools accessible to everyone, regardless of language. Every tool, label, and guide is fully translated.
All tools run entirely in your browser. No data is sent to any server. Your colors, images, and designs stay on your device.
Our mission is to make professional-grade design tools accessible to everyone, regardless of language, location, or budget. We believe that color theory, typography, and layout skills should not be locked behind expensive software subscriptions.
Every tool is optimized for speed and privacy: nothing is uploaded, no account is required, and everything works offline once the page loads. We regularly update tools based on community feedback and WCAG accessibility guidelines.
Since launch, designers from over 40 countries have used these tools to create landing pages, mobile apps, brand guidelines, and marketing materials. The site is maintained as a labor of love — updated frequently, kept ad-light, and always free at the point of use.
We believe design tools should be like a craftsman's toolbox — simple, reliable, and built to last. No account required, no software to install; just open your browser and start creating. We focus on fast load times and minimal distractions so the tools themselves remain the star of the show.
Thank you to everyone who uses, shares, and suggests improvements. Your feedback directly shapes this site: every new tool, every refinement, every detail comes from real user needs. If you have ideas or suggestions, we would love to hear from you.
All tools on this site follow WCAG accessibility standards: sufficient contrast, clear labels, and full keyboard support. We believe great design tools should embody great design principles — so every user, including those with visual impairments, can use them comfortably.
This project began in 2024 as a small collection of personal design utilities and has grown into a multilingual toolkit used by designers around the world. We remain an independent, self-funded site — no venture capital, no paywalls, no compromises on quality.
If this toolkit saves you even a few minutes each week, it has done its job. Happy designing!
