In their own words
PenPeeper
PenPeeper is an open-source penetration-testing engagement manager for security professionals. It organizes projects through Gather, Search, Findings, and Report stages, supporting multiple engagements and clients, device tags, asset filters, and targeted reports. Users can import scans, screenshots, and notes, then export complete projects as encrypted files for sharing or backup. Built-in automation integrates Nmap, Nikto, SearchSploit, WhatWeb, Enum4Linux, FFUF, and SNMP, with configurable scan concurrency. PenPeeper retrieves CVE details, severity scores, and descriptions from the National Vulnerability Database. AI features cover vulnerability hunting, evidence examination, remediation recommendations, and executive-summary generation through local or cloud providers including LM Studio, Ollama, OpenRouter, Claude, Gemini, ChatGPT, and custom providers. Guided templates and customizable summary graphics support PDF reports. The software is free for personal or professional use under its stated license terms, but selling it or hosting it as paid SaaS requires permission or is prohibited. It runs on Linux, macOS, and Windows; Windows requires Windows Subsystem for Linux. Vulnerability testing is passive and flags potential issues for manual review.
