Free Developer Tools & Accessibility Checkers

When you're building software, you don't want to break your flow state to navigate a bloated, ad-ridden SEO site just to check a hex code or verify a license. These developer tools are built for speed: zero tracking, zero ads, instant execution.

Accessibility compliance is a legal and ethical requirement, not a nice-to-have. Our Strict WCAG Contrast Math tool doesn't just give you a pass/fail grade; it calculates the exact Relative Luminance ratio required by WCAG 2.1 guidelines, helping you precisely adjust your color palettes for AA or AAA compliance. For legal and architectural compliance, the Open-Source License Conflict Checker helps you map out your dependency tree against copyleft licenses like GPL and AGPL, ensuring you don't accidentally poison your proprietary codebase.

Because these tools run entirely in the browser, your proprietary hex codes, architecture plans, and dependency lists are never sent over the network to our servers. It's safe, instant, and frictionless.
