About s2.dev
S2 is an API for durable streams. We make working with streaming data dead simple and reliable.
The more we worked on data systems, the more we felt like there was a missing building block. The seamless experience of object storage simply did not exist for durable streams – so we set out to fix that!
S2 reimagines streams as an unlimited and access-controlled web resource. Like if Kafka and S3 had a baby.
