About Yundera

Yundera and NSL.SH are built by Aptero, a French deep-tech company based in Paris and Seoul, with a branch in Chile.

What we build​

  • Yundera — a managed Personal Cloud Server platform. You get your own server with one-click app installs, automatic domains, HTTPS, and full data ownership.
  • NSL.SH — an open-source mesh network that automates domains, routing, and TLS for self-hosted applications. It gives any self-hosted app a public subdomain ({app}.{user}.nsl.sh) with automatic HTTPS, without needing a public IP, port-forwarding, or manual DNS/certificate setup.

Background​

Aptero previously built immersive 3D/WebXR experiences for global enterprises including L'Oréal, KPMG, Aéroports de Paris, and Mars. The team won the Facebook Developer Circles Community Challenge 2019 (worldwide winner from 12,000+ participants) and was the first company to build immersive 3D spaces inside Microsoft Teams.

From that foundation in immersive web and AI, Aptero now focuses on sovereign, open-source digital infrastructure — helping people own their data by making self-hosting accessible.
