About jdgrid

jdgrid is the personal hub of a Korea-based solo developer. Focused on shipping small, focused tools that do one thing well and run entirely in the browser.

What you'll find here

• Free dev utilities — see the Projects section
• Long-form technical writing tied to the tools (on yutils)
• Open-source friendly, privacy-first defaults

Operating principles

• Client-side first — user data stays in the browser whenever possible
• No login walls — tools work immediately without an account
• Honest performance — small bundles, no dark patterns
• Documentation alongside code — every tool has a guide

Stack

Next.js, TypeScript, Tailwind, Cloudflare Workers. Built and maintained by one person.
