Payment / fintech API sandbox
Plaid Sandbox
Plaid Sandbox is a free environment with mock financial data and unlimited test Items for building against Plaid before moving to Production.
Last verified 2026-07-26
Plaid Sandbox is free and uses mock data with unlimited test Items. Plaid's separate Development environment was decommissioned in June 2024, leaving Sandbox and Production, with Trial/Limited Production as free ways into real data — which is why 'sandbox vs development vs production' is still actively searched.
