An EVE-NG alternative with nothing to host
EVE-NG is often described as browser-based, and its client interface genuinely is. The part that trips people up is everything underneath: EVE-NG is a server you install on a hypervisor or bare metal, size for your topologies, and stock with network OS images you obtain yourself. The browser is the window; you still own the machine behind it.
NetForge-AI has no machine behind it that you have to care about. The simulator runs in your browser, so the only thing standing between you and a working topology is a URL.
| EVE-NG | NetForge-AI | |
|---|---|---|
| What you install | A server (bare metal, ESXi, or a hypervisor VM) | Nothing |
| Client | Browser UI to your own server | Browser — there is no server to run |
| OS images | You source, license, and upload them | Not applicable |
| Approach | Emulation — real vendor images | Simulation — behavior computed from your config |
| Editions | Community free; Pro is paid | Free plan · Pro $20/mo · Max $25/mo |
| Works on a Chromebook | As a client, if a server already exists | Yes, fully |
| Time to first ping | Hours — server build, then image upload | About two minutes |
| Packet visibility | Wireshark integration | Live animation on every cable, always on |
| Built-in curriculum | — | 8 modules · 47 chapters + quizzes + final assessment |
| Classroom features | Multi-user labs on your server | Join codes, live-synced presenting, auto-graded assignments |
What EVE-NG is genuinely better at
Multi-vendor emulation at scale. If your work involves interoperability between vendors, or you need a shared lab server that a whole team hits with large, long-lived topologies, EVE-NG is built for exactly that and a browser simulator is not a replacement.
It is also the right answer when the lab must mirror production closely enough that you would act on the result — pre-change validation, reproducing a bug, or practising for a hands-on expert exam.
The hidden cost of self-hosting a lab
The setup is not one-time. Someone keeps the server patched, manages disk as image libraries grow, sizes RAM against the biggest topology anyone wants to build, and answers for it when it is down. In a school or a small team, that someone usually did not volunteer.
For teaching specifically, this is where self-hosted labs quietly fail. A class of thirty running concurrent emulated topologies is a real capacity-planning problem. NetForge-AI sidesteps it: each student's lab runs in their own browser, so thirty students cost the same as one.
Where NetForge-AI puts its effort instead
Because there is no infrastructure to maintain, the product invests in the learning surface: continuous packet animation so protocol behavior is visible rather than inferred, an 8-module course with quizzes in the same tab as the lab, and ARIA, an AI tutor that reads your actual running config and explains why the thing you built does not work.
The honest trade is fidelity. NetForge-AI models protocol behavior faithfully — VLANs and 802.1Q, STP/RSTP/PVST+, EtherChannel, OSPF, EIGRP, RIP, BGP, VRRP, NAT/PAT, and standard plus extended ACLs — but it is not running a vendor's binary, and it does not claim to.
The fastest way to compare simulators is to send one ping. Create a free account, drop two PCs and a switch on the canvas, and watch the ARP + ICMP animation — that's the whole pitch.

Is EVE-NG free?
There is a free Community edition and a paid Pro edition with additional features. Either way the network OS images are licensed separately by their vendors and are not included, and you provide the hardware or hypervisor to run the server on.
EVE-NG runs in a browser — how is NetForge-AI different?
EVE-NG's interface is a browser client pointed at a server you install and maintain. NetForge-AI has no server component for you to run at all: the simulation executes in your browser, so there is no hypervisor, no image library, and no capacity planning.
Which is better for a classroom?
For most classrooms, the browser simulator — because per-student cost and administration are effectively zero, Chromebooks work, and NetForge-AI adds join codes, live instructor presenting, and auto-graded assignments. Choose EVE-NG when the curriculum specifically requires real vendor images.
