Duong Labs is a one-person software studio. Each product ships as a focused, one-time purchase — no subscriptions, no dashboard to babysit, no growth-hacked upsells. Code is written and reviewed line by line before anything goes out the door.
Products
Two products so far, both aimed at developers shipping their own software faster.
Slash commands and sub-agents for Claude Code and Cursor that turn “I think the agent works” into “I can prove it” — eval suites, trace review, regression checks, and red-teaming for AI agents.
A Next.js 16 starter with Google sign-in, Stripe billing, and a working Claude API route already wired together — the week of setup a new SaaS idea usually costs, done once.
Checkout
Checkout, digital delivery, and tax are handled by Lemon Squeezy, our merchant of record. Every product is sold at a fixed one-time price — you pay once, download instantly, and keep the code.
Customers find us through the Lemon Squeezy marketplace, GitHub, and developer communities such as Reddit and Indie Hackers.
