Base44

Base44 is an AI-powered full-stack app builder that converts plain-English prompts into working web applications complete with database, authentication, and hosting. Acquired by Wix in 2025 for a reported $80M plus earn-outs, it still operates as a distinct product and reached roughly $100M ARR by early 2026. It suits non-technical founders and operators who want to ship internal tools and MVPs quickly, though its credit-based pricing can grow with usage.

Base44 lets you describe an app in plain English and generates a working full-stack web application, including a database, user authentication, and hosting, without requiring you to wire those pieces together yourself. It targets non-technical founders, operators, and builders who want to ship internal tools, MVPs, and small SaaS products quickly, as well as developers who want a fast starting point. The company grew unusually fast, reportedly reaching roughly 2 million users by the end of 2025 and around $100 million ARR by early 2026, less than a year after founding. In mid-2025 Wix acquired Base44 for an initial reported consideration of about $80 million plus performance-based earn-outs paid through 2029. As of August 2026 Base44 continues to operate as its own product and brand under Wix. Pricing is credit-based, separating AI "message credits" used for building from "integration credits" consumed when the live app runs and calls external services. This model rewards fast iteration but means heavy usage can escalate costs, so it is worth monitoring credit consumption on larger or high-traffic projects.
