Caesar

Open-Source Intelligence (OSINT) & Attack Surface Reconnaissance Platform

Caesar is a full-stack Open-Source Intelligence (OSINT) and digital reconnaissance platform designed for security researchers, penetration testers, and threat analysts. Built on an edge-native serverless architecture, Caesar orchestrates decentralized intelligence collection across 50+ reconnaissance modules with real-time caching, CORS proxying, and automated forensic dossier generation.

Core Capabilities

1. Unified Investigative Dossier

Compiles cross-module findings into structured forensic dossiers:

• JSON: Machine-readable format for ingestion into SIEM, SOAR, or MISP platforms.
• CSV: Tabular evidence for compliance records, audits, and spreadsheets.
• PDF: Formatted executive intelligence summaries ready for stakeholders.

2. Multi-Tiered Edge Caching

• Production (Cloudflare KV): Globally distributed edge cache reducing upstream API latency and preventing provider rate-limiting.
• Local Fallback (LRU Cache): High-performance in-memory LRU cache for development environments.

3. Build & Chunk Optimization

Vite bundle splitting (manualChunks) isolates heavy rendering libraries (html2pdf, charting components, icon sets) ensuring sub-second initial page load and fast client-side routing.
