Yes. For developers, Plaid is free to use in our Development and Sandbox environments, allowing you to discover the product, become familiar with our APIs and endpoints, and learn how the platform works. Plaid's completely free Development environment allows you to use up to 100 Items (institution logins) with live data. Development is perfect for testing and learning more about the Plaid API, as well as for personal-use applications. Plaid will remain free for apps designed for personal use, as well. Pricing is only activated once you request Production access.
Plaid is also free for consumers (end users). We don’t charge consumers for our services.
