• ⏰ Date - Past, present, future, recent, soon... whenever!
• 💸 Finance - Create stubbed out Account Details, Transactions, and Crypto Addresses.
• 👠 Commerce - Generate Prices, Product Names, Adjectives, and Descriptions.
• 👾 Hacker - “Try to reboot the SQL bus, maybe it will bypass the virtual application!”

Note: Faker tries to generate realistic data and not obvious fake data. The generated names, addresses, emails, phone numbers, and/or other data might be coincidentally valid information. Please do not send any of your messages/calls to them from your test setup.
