Hugin vs Fiddler
A Fiddler alternative for security testing
Fiddler is a long-standing web debugging proxy, historically Windows-first, now with paid Telerik support tiers. It is a debugging tool — no vulnerability scanner, no fuzzer, no out-of-band server. Hugin is a native Rust proxy and scanner with all of those, on macOS, Linux and Windows.
Why people look for a Fiddler alternative
Debugging, not scanning
Fiddler captures and edits traffic. It has no active scanner or fuzzer. Hugin ships both, in the free Community tier.
Windows-first history
Classic Fiddler is Windows/.NET-centric (Fiddler Everywhere is cross-platform). Hugin is a single Rust binary on macOS, Linux and Windows.
Paid support tiers
Serious Fiddler use pushes you into Telerik support tiers. Hugin Community is free; Pro is €10/month with no tier ladder.
No OOB or agent
No out-of-band server, no AI agent. Hugin has a self-hosted OOB server on eight protocols and 174+ MCP tools.

Frequently asked
Is Hugin a good Fiddler alternative?

Can I keep using Fiddler alongside Hugin?
Yes. Hugin works on plain HTTP(S) traffic, so you can run it on one engagement and Fiddler on another, or A/B a target to compare coverage. Nothing stops you keeping both installed.
