Persistent AI agents that maintain and modernize a company's whole software estate, built for regulated enterprises.

## Overview

AppFactor runs persistent AI agents that maintain and modernize a company’s whole software estate. They map what is running, fix bugs, patch security holes, upgrade dependencies, rewrite code in Rust and move apps into containers. Engineers approve every change, and nothing merges itself.

It is built for regulated enterprises such as banks, healthcare and government, and deploys in the customer’s private cloud account or on-premises, including air-gapped environments. It works with OpenAI, Anthropic, Google, open-source or local models.

Its MCP Bridge tool turns existing APIs into tools agents can call. No prices are published.

**Who it is for:** Regulated enterprises such as banks, healthcare and government.
