Replit

Replit's Agent builds apps, websites, designs and slide decks from a chat. It handles authentication, a database, hosting and monitoring without setup, connects to more than 100 integrations, and can build native mobile apps and upload them to App Store Connect. Free Mode lets you brainstorm and build without token costs, while Power and Max modes offer more capable models, and Max routes each task to a suitable model. An infinite canvas lets you adjust designs visually.

The free Starter plan includes limited Free Mode use. Core costs $20 a month ($18 billed annually) and adds $20 toward more capable models; Pro is $100 a month with 10 parallel agents. Work beyond your allowance is charged by effort, so complex requests cost more than simple ones.
