In
detail.
Where Hugin actually wins, and why.
vs Burp Suite
Active scanner in Community
Burp locks its active scanner behind the $499/year Professional license. Hugin's Community tier ships 55 active checks and 48 passive checks, with the same OOB blind detection and scan profiles. No rate limits.
Intruder at full speed
Burp Community throttles Intruder. Hugin Community runs it at full speed — 21 payload generators, 32 processing rules, four attack modes plus a single-packet race mode and Turbo raw-TCP batching.
Native runtime
Burp runs on the JVM: slow cold start, multi-gigabyte memory footprint. Hugin is a single native Rust binary — sub-second startup, low memory use.
MCP tools built in
Burp's MCP support is an add-on — the official Burp MCP Server extension. Hugin exposes 169 MCP tools built in, no extension, driving the proxy, scanner, intruder and decoder directly.
Race conditions built in
Burp added the single-packet attack to Repeater. Hugin ships a dedicated engine: single-packet attacks, last-byte sync, and barrier coordination.
vs Caido
Deeper scanner coverage
Caido's official scanner (2025) covers the common classes — reflected XSS, SQLi, SSRF, CORS, command injection — with a smaller, open-source check set. Hugin includes 55 active checks with blind OOB detection across six protocols, plus 48 passive checks on every response — Community tier.
MCP tooling
Caido's Shift AI (acquired 2025) is agentic but plugin-scoped and paid-tier. Hugin ships 169 MCP tools covering scanning, fuzzing, smuggling, deserialization, SSRF, cache poisoning and OAuth abuse.
Offline operation
Caido requires an account and re-validates online — it stops running after about a week offline. Hugin Community runs fully offline with no account, all data in local SQLite.
Sandboxed extensions
Caido plugins run in a JavaScript runtime. Hugin's Synaps modules compile to WASM and run in Wasmtime with a 1 billion instruction fuel cap and a 16 MB memory limit.
