The big win: ULIDs sort by creation time as plain strings — which makes them perfect as database row IDs, log keys, or anywhere you want ordering for free. The 26-character Crockford-base-32 encoding is URL-safe and case-insensitive. Generate one or many at once (up to 100), or override the timestamp to produce a ULID for any past or future moment. Runs entirely in your browser.","category":"text","categoryName":"Text & Encoding","keywords":["ulid generator","ulid online","generate ulid","ulid vs uuid","sortable id generator","lexicographic uuid alternative","monotonic ulid","ulid timestamp","ulid decoder","crockford base32 id","unique sortable id","ulid free online","ulid for database","ulid bulk generator","primary key generator"],"badge":"Generator","url":"https://toolsly.tools/ulid-generator","inputs":[{"type":"number","key":"count","label":"How many to generate","defaultValue":1,"min":1,"max":100,"step":1},{"type":"text","key":"timestamp","label":"Override timestamp (optional)","defaultValue":"","placeholder":"ISO date (2024-01-15T12:00:00Z) or millis (1705320000000)","help":"Leave empty to use the current time."},{"type":"boolean","key":"monotonic","label":"Monotonic within the same millisecond","defaultValue":true,"help":"Guarantees a→b→c sort order even when generated in the same ms."}],"outputs":[{"key":"ulids","label":"ULIDs","multiline":true},{"key":"firstTimestamp","label":"First ULID's timestamp"},{"key":"summary","label":"Summary"}],"invocation":{"webUi":"https://toolsly.tools/ulid-generator","api":null,"notes":"Currently invoked via the web UI at `webUi`.
