Snowflake ID Decoder

Deconstruct 64-bit distributed IDs instantly.

Snowflake IDs are 64-bit integers used by distributed systems like Discord and Twitter to generate unique identifiers at high scale. Because standard JavaScript numbers lose precision on 64-bit integers, decoding them manually is error-prone. This utility uses native BigInt operations to safely deconstruct Snowflake IDs into their exact timestamp, worker ID, and sequence number without sending your data to a server.
