About a16z - AI-Powered Web App Builders Market Map - February 2025
Andreessen Horowitz's February 2025 market map analyzing the rise of AI-powered web app builders. The report covers key players like Bolt, Lovable, and v0, their revenue growth (Bolt reaching $20M, Lovable $10M run rates), and the emerging LLM-based app stack that abstracts coding into natural language and pixels. It distinguishes between static website generation and dynamic application generation, discusses code export capabilities, and outlines the technical architecture of text-to-web app products. Authored by Justine Moore, Yoko Li, Gabriel Vasquez, Marco Mascorro, and Bryan Kim.

FAQ
What are the main categories of AI web app builders covered?
The market map distinguishes between static website generators (primarily informational with basic interactivity) and dynamic application generators (stateful, requiring third-party tools like databases and authentication). Static sites are easier to generate and can be template-based, while dynamic apps enable complex actions like CRUD and user login.
How do text-to-web app products typically work?
Most products follow a similar simplified architecture where an LLM generates code based on user input. The process involves natural language or pixel-based input, which is processed through design, image, site generation, and hosting components. The new abstraction for non-technical users is pixels and natural language, compared to SDKs and frameworks for developers.
What growth metrics does the report highlight?
Based on publicly released metrics, Bolt scaled to a $20M revenue run rate, and Lovable grew to $10M, each within two months of beginning monetization.
