BuildId Service

BuildId

BuildId is a tiny HTTP service for lexicographically sortable IDs.
Use it for build numbers, release tags, and document workflows.
Sequence state is kept per running instance.

If you wonder why you would ever need this, you probably do not need it ;-)

Need faster responses and dedicated sequence space without competing for numbers?
You can absolutely do it yourself, but getting in touch is usually faster.
