Built on Openness, Driven by Technical Excellence
Upstream First
We contribute to open-source communities first. Through a dual-license model — AI context (.agents/) under CC-BY-SA 4.0 and source code under Apache 2.0 — we propose a new contribution infrastructure that keeps the open source ecosystem sustainable in the vibe coding era.
Data-Driven Transparency
All Nextain technical decisions are based on transparent data and logic, providing our partners and customers with a predictable and reliable development environment.
Robust AI Infrastructure
We focus on solving the security and system fragmentation challenges enterprises face when adopting AI, building a sustainable infrastructure ecosystem.

The Era of Vibe Coding: AI for Everyone
"Open source enabled vibe coding, but vibe coding must not destroy the open source ecosystem that made it possible. As AI generates more code, the vessel that holds it must be even more solid and open. Nextain proposes a dual-license model that protects AI context (.agents/) as intellectual property while keeping it open source. An architecture where AI agents themselves attribute sources, suggest voluntary donations, and sustain the open source ecosystem — this is our vision for a sustainable AI era."
