FutureIs Arki for you?
Better to know before you buy. Arki fits some projects perfectly and is the wrong tool for others.
Arki is for you if
- You want to launch a SaaS without spending weeks wiring login, payments, emails, and database.
- You work with Next.js and TypeScript, or you are ready to.
- You build with AI (Cursor, Codex, Claude) and want a solid, tested base where agents make good decisions.
- You prefer to pay once and own the code, with no monthly platform fee.
Arki is not for you if
- You are looking for a no-code tool or visual builder. Arki is source code.
- Your product will run on another stack, like PHP, Rails, or Django.
- You expect a finished product to resell without writing any code.
- You only need a landing page. Arki is the full system behind a SaaS.
Who is behind Arki
Arki comes from years building products, scaling teams, and seeing how much time and money are lost without a truly ready foundation.
Lincoli Xavier
Software Engineer · Digital Nomad · Skydiver
I built Arki as a stack that removes setup friction for professionals who want to launch products faster. The goal is simple: remove infrastructure weight so you can focus on growth.
- 14+ years building production software with TypeScript, Node.js, React, Next.js, Vue, and Nuxt.
- Technical leadership in real products, connecting business, architecture, and delivery.
- XP practices in daily work: pair programming, simple design, refactoring, and CI/CD.
When I am not coding or sketching new ideas, you will probably find me jumping out of a plane or on an island in Thailand.
