Hack the Route vs GNS3
Pick GNS3 if you want to build large, custom topologies from real router and switch images on your own computer: it is free, open source and very flexible, but you supply the images and set it all up. Pick Hack the Route if you want ready-made labs on real Linux machines in your browser, with steps to follow, checks on your work and faults to fix, and nothing to install or configure.
Side by side
| Hack the Route | GNS3 | |
|---|---|---|
| Runs on | Real Linux machines on real links: each lab is a small network | An emulator: real network operating system images, virtual machines and containers that you supply |
| Install | Nothing to install | A desktop app, usually with the GNS3 VM or a server of your own to run the images |
| In the browser | Yes: the shells, the map and the packet capture all open in a browser tab | No hosted labs: it runs on your computer or a server you set up |
| Guided steps and checks | Every lab says what to run and why, checks what you did, and has faults to switch on, find and fix | A blank canvas: you design the topology and the exercises, or follow a course from elsewhere |
| Price | Free: 14 labs, no card. Pro: $15 a month or $120 a year for all 99 labs | Free and open source; the device images are yours to get and license |
| Focus | Linux networking: addressing, switching, routing, DNS, packets, network security and troubleshooting | Any topology you can build, with images from Cisco and other vendors, for study, practice and testing designs |
When to pick GNS3
- You need a vendor's real operating system, such as Cisco's or another vendor's images, and its exact behaviour.
- You want to design big or unusual topologies of your own, or test a design before you build it for real.
- You want it all free and on your own hardware, and you do not mind setting it up.
