ID & Random Generator
UUID v4, NanoID, random integers, and lorem ipsum placeholder text.
Generating UUIDs, NanoIDs, and placeholder text
UUID v4 provides 122 bits of randomness in standard string format. NanoIDs shorten URLs while maintaining collision resistance with larger alphabets. Lorem ipsum fills layout mocks without meaningful content.
Random integers need explicit min/max and rejection sampling when uniformity matters. Placeholder text must not ship to production SEO pages.
Seed documentation when IDs must reproduce across test runs.
Generate identifiers locally for load test datasets without sending ranges to remote services.
