Everything you need to simulate
enterprise networks
From drag-and-drop topology design to real-time packet simulation, validation, and professional documentation — all in your browser.
Core Capabilities
Built from the ground up for network engineers and students who demand precision.
Real-time Simulation Engine
Watch packets traverse your network in real-time with deterministic scheduling. ARP resolution, ICMP ping, MAC learning, and full L2/L3 forwarding — all computed locally in your browser with zero latency.
Drag-and-Drop Topology Canvas
Design complex network topologies visually. Drag hosts, switches, and routers onto the canvas, connect them with links, and configure IP addresses and interfaces — all without writing a single line of config.
Instant Validation
11 built-in validation rules catch issues before they become problems. Detect duplicate IPs, subnet overlaps, missing routes, gateway inconsistencies, VLAN mismatches, and ACL conflicts automatically.
Team Collaboration
Work together on shared topologies in real-time. See team members' presence, broadcast changes instantly via Supabase Realtime, and track who modified what with version history.
Export & Documentation
Generate professional network documentation, IP addressing plans, and validation reports in one click. Export labs as JSON for backup, sharing, or migration between environments.
Workspace Management
Organize labs into workspaces with role-based access control. Invite team members as owners, admins, members, or viewers. Manage billing and plans per workspace.
Full Protocol Stack
Production-grade protocol simulation with deterministic scheduling.
Five Modes de Travail Intégrés
Switch seamlessly between design, simulation, validation, troubleshooting, and documentation.
Design
Build and configure your topology with drag-and-drop devices, link connections, and IP configuration.
Simulate
Run simulations and watch packets flow through your network. Inspect ARP tables, routing tables, and MAC tables in real-time.
Validate
Run 11 automated validation rules to catch misconfigurations, IP conflicts, and routing issues before they become problems.
Troubleshoot
Analyze packet flows, inspect device state, and debug connectivity issues with detailed event logs and packet timelines.
Document
Generate professional HTML reports with network summaries, addressing plans, and validation results.
