I'm Duoc, a solo developer. I build small, focused tools for developers, readers and online stores, each one born from a problem I ran into myself.

Why I Build What I Build

Small inefficiencies annoy me, so I build tools that remove them, then share the tools so other people can skip the annoyance too. Everything here is designed, built, shipped and supported by one person.

  • Built to fix my own itch
  • Small and focused
  • Support straight from me
  • Shaped by your feedback

Built for People Like Me

I make tools for people who want to get things done without ceremony. There is no sales team and no roadmap committee. If something is broken or missing, you talk to the person who can fix it.

Hi, I'm Duoc 👋

I'm a solo developer who builds tools to make everyday work easier. Use what helps, tell me what's missing, and I'll keep improving it.

Frequently asked questions.

You can always refer to the Help Center, but here are a few answers to common questions.

What do you build?

Small tools I wish existed: developer utilities, Shopify apps, reading and document tools, automation and AI helpers. Each one solves one specific problem.

Just me, Duoc. I design, build, ship and support everything myself, so changes are quick and your feedback goes straight to the person who can act on it.

Email [email protected] or use the live chat on the site. I reply personally, usually within about a day. Feature requests are welcome.

Found something useful?

Give it a try.

Every tool here started as a fix for my own problem. Try one, and tell me what works and what doesn't.
