Why Archaeode?

Legacy code isn't dead code. It's undocumented, misunderstood, and mission-critical.

Auto-Documentation

Generate function-by-function documentation, business logic extraction, and security analysis from undocumented legacy code.

Code Modernization

Convert COBOL, C, Fortran to modern Python 3.12+ while preserving business logic. Side-by-side comparison included.

Security Scanning

Identify CVE vulnerabilities, buffer overflows, SQL injection patterns, and security risks in legacy codebases.

Multi-AI Backend

Powered by Gemini, Claude, and local Ollama. Choose cloud for speed or on-premise for data privacy.

On-Premise Ready

Deploy on your own servers with Docker. Your code never leaves your infrastructure. Perfect for banking & compliance.

ROI Calculator

Build a business case with our interactive ROI calculator. Show stakeholders the exact cost savings and payback period.

How It Works

Three steps from legacy confusion to modern clarity.

1

Upload Code

Paste or upload your COBOL, C, or Fortran source files. Supports files up to 500KB.

2

AI Analyzes

Gemini AI reads every function, extracts business logic, maps dependencies, and finds vulnerabilities.

3

Get Results

Download documentation (Markdown/PDF), modernized Python code, and security reports.

"The lack of documentation is the real crisis in legacy systems. Tools like this are exactly what the industry needs."
