Caido vs PenPeeper

Caido is a web security auditing toolkit for scaling manual testing through AI and teamwork. Its proxy intercepts and monitors HTTP and WebSocket traffic, with history for intercepted traffic and WebSocket messages. HTTPQL filtering lets users search requests and responses. Node-based workflows support ad-hoc automation, and automated attacks can use custom payloads and placeholders. Users can connect existing LLM providers, including Anthropic, Google, OpenAI, and providers available through OpenRouter. AI agents can access Caido programmatically through its Client SDK. Community plugins and custom extensions are supported; the Basic plan allows three plugins. Basic is free forever and includes two projects, seven workflows, five filter presets, and one pipeline session at a time. The pricing note lists paid access from $20/user/mo, while the opened pricing page did not display prices for Individual, Team, or Enterprise. Caido lists Linux, macOS, Windows, web, API, and self-hosted platforms, and presents the product for pentesters, security engineers, and bug bounty hunters.

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.
