How it works

Six-phase intelligent pipeline

Our Contract-First Batch Conversion methodology ensures consistent, production-ready output. Not naive translation — deep semantic understanding.

Phase 0

Contract Generation

Pre-declares all file paths, class names, and method signatures before any code is written.

Phase 1

Skeleton Generation

Creates a compilable project structure that matches the contract exactly.

Phase 2

Test Extraction

Derives behavioral test cases from source analysis — no runtime access needed.

Phase 3

Batch Conversion

Converts code layer-by-layer with adaptive complexity batching via Claude AI.

Phase 4

Stitch Pass

Resolves all imports, method calls, and fills remaining stubs across files.

Phase 5

Behavioral Verification

Runs tests in a Docker sandbox with up to 3 auto-fix cycles for >95% pass rate.

Before & After

Not line-by-line translation. Deep semantic understanding that produces idiomatic, modern code.

# Legacy API endpoint
from flask import Flask, request
import MySQLdb

app = Flask(__name__)

@app.route('/api/users', methods=['GET'])
def get_users():
    db = MySQLdb.connect("localhost",
        "root", "password123", "mydb")
    cursor = db.cursor()
    name = request.args.get('name')
    # SQL injection vulnerability!
    query = "SELECT * FROM users WHERE name='%s'" % name
    cursor.execute(query)
    results = cursor.fetchall()
    return str(results)

Features

Everything you need to modernize

From code intelligence to cloud deployment — a complete, end-to-end platform.

Deep Code Intelligence

Multi-language semantic parsing using Tree-Sitter. Extracts functions, classes, APIs, SQL queries, call graphs, and cross-file dependencies automatically.

AI-Powered Conversion

Powered by Anthropic's Claude AI with adaptive granularity batching — complex functions get dedicated calls, simple files are batched together.

Behavioral Verification

Auto-generated test cases verify functional parity in a Docker sandbox. Up to 3 automated fix cycles ensure >95% test pass rate before delivery.

Security-First Pipeline

Semgrep SAST scans detect SQL injection, XSS, and OWASP Top 10 violations. Vulnerabilities are fixed during conversion, not after.

Real-Time Monitoring

Live WebSocket streaming of conversion progress. Per-phase indicators, log streaming with searchable history, and test execution results as they happen.

Vulnerabilities shipped

Security

Security-first, not security-later

Vulnerabilities are detected in your source code and eliminated during conversion — not shipped and patched after.

SQL Injection Detection

Identifies string concatenation in queries and converts to parameterized statements automatically.

Cross-Site Scripting (XSS)

Detects unescaped output rendering and applies proper sanitization in converted code.

Insecure Auth Patterns

Flags hardcoded credentials, weak hashing, and missing encryption — replaces with secure alternatives.

OWASP Top 10 Coverage

Comprehensive Semgrep ruleset covers the full OWASP Top 10 vulnerability categories.

SQL Injection — user_controller.py:42 Auto-fixed
