About Us

Toolbox (codexapp.cc) is a free platform combining online tools and resource discovery. We curate practical, ready-to-use tools across 12 categories: image, text, developer tools, calculators, random decision, files & documents, QR codes, system scripts, command cheatsheets, AI tools, creative demos and education. We also maintain curated directories of MCP servers, Agent skills, AI products, developer resources and open-source GitHub projects.

• Open and use instantly, no sign-up required
• Data never leaves your browser — tools run locally
• Permanently free, no usage limits
• Continuously adding new useful tools and resources
• Bilingual interface (Chinese / English)

For tools, we prioritize high-frequency, practical, browser-local utilities. For resources, we manually curate MCP servers, AI products, Agent skills, frameworks and learning materials so developers can discover everything in one place.

This site is built with TanStack Start and deployed on Cloudflare Workers. Pages are server-side rendered for performance and SEO; all tool logic runs locally in your browser.
