Duo Dev
A free collection of 74+ tools designed for everyday tasks — from minifying code to generating sitemaps. No account required, no limits.
ToolByte is a comprehensive collection of free online tools built for developers, digital marketers, and web professionals. Every tool runs directly in your browser with no installation, no sign-up forms, and no usage limits. Whether you need to minify CSS, generate a sitemap, convert text formats, or work with PDFs, ToolByte has you covered.

Now, all these utilities live in one place, maintained to the same standard and always available.
