Generate various types of unique identifiers for software development and data management. Select an identifier type from the dropdown: UUID v4 (random), UUID v7 (time-ordered), ULID, Nano ID (configurable length), or SWHID (Software Heritage Identifier). Configure any type-specific options such as ID count or Nano ID length. For SWHID, choose the input method — upload a file, type text, or fetch a URL. The system computes the appropriate hash and constructs the identifier. ⚠️ Important: Download your generated identifiers before navigating away. Save them in PDF, DOCX, JSON, CSV, TXT, XML, or HTML format.
