Frequently asked questions
Are IDs from KSUID Generator safe for production?+
They follow the published specification and use the browser's cryptographically secure randomness where applicable. Because nothing is transmitted, they're also safe to generate for sensitive systems.
Why use this instead of a plain auto-increment?+
Time-sortable, collision-resistant IDs are URL-safe, don't leak row counts, and can be generated client-side before a database round-trip — ideal for distributed systems and event logs.
Is KSUID Generator free?+
Yes. KSUID Generator is completely free with no sign-up, no account, no usage limits and no watermarks. Use it as often as you like.
Does KSUID Generator send my data to a server?+
No. KSUID Generator runs entirely in your browser with JavaScript — your input never leaves your device, which makes it safe for private API payloads, schemas and source code.
