CST VerdictBased on our analysis of available product data, here is our conclusion:
Penetration testers doing manual path traversal testing will appreciate liffier for its speed; the tool automates the tedious work of incrementally testing ../ sequences across endpoints, cutting reconnaissance time on misconfigured directory structures. At 11 GitHub stars and zero dependencies, it's lightweight enough to slip into any engagement workflow without setup friction. Skip this if you need automation across multiple vulnerability classes or reporting integration; liffier does one thing and makes no apologies for it.
Solo penetration testers and small AppSec teams will move faster with Caido because it strips away the UI bloat that slows down manual web testing; you get request interception, fuzzing, and scanning without the enterprise overhead that makes Burp Suite feel like piloting a cargo ship. The free pricing eliminates procurement friction entirely, which matters when you're justifying tooling spend to finance. Skip this if you need SAST integration, collaborative workspace management for large teams, or NIST Respond capabilities like automated remediation workflows; Caido is built for hands-on auditing, not orchestrated enterprise remediation.
