Enterprise platform where thousands of AI agents map a large codebase, then plan and write features, refactors and modernization.

## Overview

Blitzy is an enterprise platform for autonomous software development on existing codebases. Thousands of AI agents read and map a large codebase, then plan and write code for new features, refactors, documentation, tech debt and modernization, and open pull requests.

Customers bring requirements and approve the technical plan first; agents can then run for days or weeks. Blitzy says it delivers more than 80 percent of a project, with people reviewing the output and finishing the rest.

It runs in Blitzy’s cloud or in the customer’s own cloud account or on-premises, and holds SOC 2 Type II and ISO 27001. Pricing is by contract, at $0.10 per line of code read and $0.20 per line written, with a free sandbox.

**Who it is for:** Large enterprises.

## Features

* Reads and maps large existing codebases before planning work.
* Runs thousands of specialized agents across multiple foundation models.
* Customers approve a technical spec before code is written.
* Opens pull requests with tested code for features, refactors and modernization.
* Priced per line of code read and written.
