What you can build with GNS3 Server
GNS3 (Graphical Network Simulator-3) is an open-source network emulation platform trusted by network engineers, students, and certifications trainers worldwide. It lets you build complex multi-vendor network topologies using real Cisco IOS, Juniper, and other vendor images alongside lightweight virtual appliances, all without physical hardware.
Running GNS3 Server on a VPS keeps your lab persistent and accessible from any browser. Projects, device images, and topologies are stored on durable named volumes so your work survives container restarts. The bundled web UI connects directly to the server API on port 3080, giving you a full drag-and-drop topology editor from any browser on any device.

I'm incredibly happy with Hostinger's VPS hosting! Their uptime is consistently top-notch, keeping my site running smoothly. Whenever I've needed help, their technical support team has been quick, knowledgeable, and genuinely helpful.

Finally a VPS hosting company that does it right! Well-priced. Excellent portal that respects their users' time. Seamless backups. Good support. Reliable. Feels rock-solid.
I reached out to Hostinger support after losing access to my self-hosted n8n instance, and I couldn’t be more impressed. Kodee and Mohammad from the support team were incredibly patient and thorough.
Many thanks to Carla for helping me with this N8N upgrade on my Hostinger VPS. Professional and knowledgeable, thank you again Carla.
Hostinger VPS is absolutely outstanding. It just always works. It is always fast and stable. Never down, never crashes.
The company is doing well, I am very happy with the specific services I use through them. Not as expensive as some places with really great VPS set ups and price plans.
