Batfish vs EVE-NG

Batfish is an open-source tool for analyzing network device configurations and validating network behavior. It works from configuration files, so core analysis does not require direct access to network devices. Teams can inspect deployed configurations and check planned changes before deployment. Checks cover undefined references, MTU and AAA settings, template compliance, sensitive-service reachability and expected traffic paths. Batfish can test whether end-to-end reachability survives any single-link or single-device failure, compare current and planned reachability, assess ACL or firewall changes and evaluate functional equivalence across vendors. Pybatfish provides a Python 3 SDK, and example Jupyter notebooks are available. An all-in-one Docker container bundles Batfish and notebooks. It runs on operating systems supporting Docker. Documented support includes Arista, AWS, Azure, Cisco, Juniper, Palo Alto Networks and SONiC, while Aruba, Dell Force10 and Foundry have limited support.

EVE-NG is a clientless network emulation platform for network, security, and DevOps professionals. It is presented for building virtual proof-of-concept projects, solutions, and training environments for organizations, educators, individuals, and groups. A topology designer supports lab creation, configuration import and export, XML lab files, and picture or map imports. Running nodes can connect through hot links, including to real networks. Listed Professional features include KVM hardware acceleration, Docker and custom Docker support, and up to 1024 nodes per lab. Integrations include RADIUS and Microsoft Active Directory authentication, Docker-integrated Wireshark, and an integrated NAT cloud. Hosting options include Proxmox, VMware platforms, and Google Cloud platform VMs. The free plan allows 7 nodes per instance and 63 per lab, with the Admin role only. EVE-NG Base and RBL are priced on request; RBL supports multiple roles, with added roles priced separately. Community Edition support and end of life ended in June 2026.
