Enterprise firewall power, built for everyone.

Songbird closes the gap between difficult community firewalls and expensive enterprise platforms — delivering strong capabilities, clean GitOps operations, and an interface that does not require specialist knowledge.

Why Songbird exists

A practical frustration: many open source firewalls are hard to operate, fragmented, or limited compared to enterprise products. Songbird was started to change that.

Simplicity without compromise

Approachable workflows combined with the power normally expected from commercial firewall platforms. Good security tooling should not require unnecessary complexity to be effective.

Free and open source

Powerful firewall capabilities should remain available to everyone — not only to teams with enterprise budgets. The project is released as open source software for this reason.

Fast by design

Built on top of eBPF to get filtering speed even with commodity hardware.

Engineering discipline

Songbird is grounded in software engineering principles instead of ad-hoc feature accumulation.

  • Design and specification precede implementation.
  • Software engineering methodology guided by SWEBOK.
  • Version control and peer review are core to the process, not just tooling choices.
  • Documentation and contribution clarity are as important as code quality.

AI as an implementer

The project uses AI in a deliberate and bounded role: as an accelerator for implementation, not as an autonomous product designer.

AI tools act as "monkey programmers" — they implement what has already been designed, specified, and reviewed by the team, with no space for autonomous creative decisions.

This keeps the codebase coherent, reduces accidental complexity, and aligns contributors around explicit design intent.

What the project aims to deliver

The focus is on product vision and coherent direction, leaving the implementation to evolve responsibly under engineering discipline.

Operational clarity

  • Reviewable changes through Git-driven workflows.
  • Predictable deployments and safer collaboration.
  • Clear separation between design, implementation, and validation phases.

User-first security

  • Clean and fast UI.
  • Responsive layouts that work on phones, tablets, and desktops.
  • Simple to understand and to operate.

Contributors are welcome

Songbird is built in the open. Whether your contribution is code, design review, documentation, testing, or product thinking, disciplined collaboration is at the heart of the project.
