PenPeeper review
An open-source desktop workspace for AI-assisted vulnerability hunting and reporting.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
PenPeeper is an open-source penetration testing engagement management system for security professionals. It runs as downloadable desktop software on Windows, macOS, and Linux, combining automated scanning, vulnerability research, AI-assisted analysis, finding management, evidence handling, and report generation. It is suited to testers who want one workspace for organizing devices, findings, evidence, and reports across multiple projects rather than a tool focused only on a single scan type.
Its strongest fit is its connected assessment workflow. PenPeeper integrates with Nmap, Nikto, SearchSploit, WhatWeb, Enum4Linux, FFUF, and SNMP, while NVD integration provides CVE information. It also supports external scan and screenshot imports, advanced filtering by service, port, protocol, vendor, banner, and tags, plus finding creation and incomplete-finding tracking. AI-assisted hunting can connect with LM Studio, Ollama, OpenRouter, Claude, Gemini, and ChatGPT. These capabilities give security teams a broad way to bring reconnaissance results and research into an engagement record, although the available integrations still center on a desktop, on-premise workflow.
Reporting and project handling make PenPeeper practical for engagements that need organized evidence and client-facing documentation. PDF reports include executive summaries, and encrypted project export and import support collaboration or backup. The trade-off is scope: PenPeeper’s direct testing coverage is narrower than platforms built around a wider range of testing capabilities. Choose it for open-source engagement management, AI-assisted vulnerability research, and tool aggregation. Teams seeking broader direct testing coverage or a browser-first operating model should consider a different category option.
