Replit is a cloud-based development environment where users write, run and deploy software directly in the browser. Its AI assistant, Replit Agent, builds applications from natural-language descriptions, which has made the platform popular for prototyping and for people who do not code professionally.
Models
Replit describes itself as model agnostic. In October 2026, CEO Amjad Masad said that OpenAI models had become the default behind Replit Agent while Anthropic’s Claude models remain selectable by users; see our news story on Replit making OpenAI its default. Pricing and plan details change, so check the company’s pricing page.
