Apify is the largest marketplace of tools for AI. At its core is Apify Store, a marketplace where builders create, publish, and monetize tools called Actors. Actors are serverless cloud programs that get web data and automate tasks on the web. Builders create them with JavaScript or Python. Build an Actor once and publish it to Apify Store. Thousands of builders already have. Earn when others use it - Apify handles all the infrastructure, billing, and monthly payouts. For everyone else, Apify means never building from scratch.
