Goal
Compare VEX-NX to common lab platforms with factual positioning (not marketing scores).
Short summary
| Platform | Strengths (typical) | Trade-offs |
|---|---|---|
| VEX-NX | Multi-vendor QEMU/Docker/IOL/Dynamips; modern web UI; Assist (NL + config remap); ScriptPad day-0; SecureCRT/PuTTY helper; REST + REST MCP tools; OVA and bare-metal | You supply proprietary images; Assist needs an OpenRouter key; nested virt required for heavy guests on VMware |
| Cisco CML | Cisco-supported reference images ecosystem; mature API-first model; strong automation story; CML 2.x adds MCP-oriented AI tooling | Cisco-centric image model; multi-vendor depth depends on what you add externally |
| EVE-NG | Broad multi-vendor community; large ecosystem of how-tos; HTML5 / client packs | Edition differences; AI not a primary built-in product story |
| PNETLab | Multi-vendor lab ecosystem related to EVE-style workflows | Documentation and automation depth vary by deployment |
VEX-NX does not claim to replace Cisco's official image distribution. CML remains the strongest choice when you need Cisco-backed reference platforms and their published API/MCP documentation model.
Where VEX-NX focuses
- Multi-vendor labs with user-supplied images and Compatibility tracking
- Assist (all editions, needs OpenRouter): natural-language lab help, config generation, Migrate Lab / Map / Remap / Redesign from running-configs
- Consoles: HTML5 plus Windows Client Pack for SecureCRT/PuTTY
- Automation: JWT REST API; MCP tool catalog over REST (
/api/v1/mcp/tools,/api/v1/mcp/call) on all editions - not a stdio MCP transport yet - Classroom sharing on all editions; classroom timers require Enterprise
Honest limits
- Proprietary guest OS images are never bundled
- Nested virtualization under VMware is slower than bare-metal KVM for Junos / NX-OS / large Cisco guests
- LDAP / SSO / RADIUS require Enterprise; SAML/OIDC full IdP redirect is still a stub (settings UI + clear unavailable login messages ship today)
- Competitive feature tables with star ratings are avoided here - editions and limits change; see Features
