Bug bounty hunters and small penetration testing teams running lightweight engagements will move fastest with Interlace because it eliminates the scripting friction that wastes hours on workflow glue work. The free pricing and 1,265 GitHub stars signal active adoption among independent security researchers who value automation without engineering overhead. Skip this if your team needs advanced reporting, compliance artifacts, or integration with enterprise ticketing systems; Interlace solves the tactical threading problem, not the documentation one.
Penetration testers and AppSec engineers who need to manipulate WebSocket traffic during assessments will find WSSiP indispensable; it's the only free proxy that intercepts and rewrites Socket.IO messages without requiring protocol-level packet crafting. The 452 GitHub stars and active maintenance signal a tool actually used in real engagements, not abandoned ware. Skip this if you're looking for automated WebSocket vulnerability scanning; WSSiP is a manual testing instrument that demands you know what you're looking for.
