FAQ
Common questions and answers about this topic.
What is a Snowflake ID?
A Snowflake ID is a 64-bit unique identifier scheme originally created by Twitter. It encodes a timestamp, worker/datacenter ID, and sequence number into a single integer.
When should I use Snowflake IDs?
Use Snowflake IDs in distributed systems that need sortable, unique identifiers without central coordination, such as microservices, message queues, and sharded databases.
How is Snowflake ID different from UUID?
Snowflake IDs are 64-bit (smaller than 128-bit UUIDs), time-sortable, and include machine/datacenter information. UUIDs are more widely standardized but larger and not inherently sortable.
Is my data sent to any server?
No, Snowflake ID generation runs entirely in your browser. The IDs are computed locally with JavaScript and never leave your device.
