Python API and utilities for Batfish
Decision gist · record as of 2026-08-14
Yes, if you operate a network and need pre-deployment validation. Pybatfish is actively maintained, has low install friction, and solves a real gap in network automation by providing correctness guarantees without live device access. The permissive Apache 2.0 license poses no restriction. Caveat: Batfish server must be installed separately, which adds operational overhead; evaluate that dependency against your deployment model.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Batfish server must be installed and running separately; pybatfish is a client library only and cannot function standalone.
- Low install friction with a pure-wheel distribution and common dependencies.
- Actively maintained with recent releases; last commit 2026-08-12 and 242 repository stars indicate ongoing development.

What it is and what it does
Pybatfish provides a Python interface to Batfish, a network configuration analysis engine that validates device settings for correctness without needing live network access. It reads device configurations (from routers, switches, firewalls, etc.) and checks them against security policies, reliability requirements, and compliance rules—catching misconfigurations before deployment. The tool can verify end-to-end reachability, test how configurations behave after link or device failures, validate ACL and firewall rules, and compare configurations across vendors.
The package wraps Batfish's analysis capabilities in a Python API suitable for automation workflows, Jupyter notebooks, or integration into CI/CD pipelines. It depends on standard libraries like pandas, requests, and PyYAML for data handling and communication with a separate Batfish server instance. Network engineers use it to close the gap between configuration changes and deployment by proving correctness before changes go live.
Use it for
- Validate network configuration changes before deployment to catch policy violations and misconfigurations early
- Test end-to-end reachability and verify that single-link or single-device failures don't break critical paths
- Verify that ACL and firewall rule changes are correct and don't inadvertently block legitimate traffic
- Check configuration compliance against organizational standards (MTU, AAA, NTP, SSH settings, etc.)
- Analyze network behavior across different vendor devices to ensure functional equivalence
- Integrate network validation into automation workflows and CI/CD pipelines for continuous compliance
