UUID Builder

UUID Builder is a free UUID/GUID generator for developers, low-code builders, no-code makers, and automation users. It helps users generate unique identifiers for databases, API records, app prototypes, workflow automation, test data, user records, uploads, invites, and temporary objects. The tool supports UUID v1, v3, v4, v5, and v7, including bulk generation, copy-to-clipboard, text download, UUID version comparison, and code examples. UUID Builder is especially useful when working with tools like Airtable, Bubble, Retool, Xano, Supabase, Make, Zapier, internal tools, databases, and backend APIs where unique IDs are often needed.
