Apache Pekko is a fork of Akka 2.6.20 originally released in September 2022. It is a member project of the Apache Software Foundation and licensed as Apache v2.
Apache Pekko released version 1.0 on July 13, 2023. Pekko does not provide a compatibility and interoperability policy statement between Akka and Pekko for SDKs, binaries, or modules. Pekko has stated that Akka and Pekko nodes are not able to form clusters together.
Lightbend provides support for Pekko v1.0.x users. We are unaware of other commercial software vendors providing a Pekko support commitment.
For more information, please contact us.
Lightbend has been SOC 2 audited since the Akka 23.05 release on April 25, 2023. All earlier open source and forked versions before Akka 23.05 are not SOC 2 compliant. Organizations that require compliance with SOC 2, NIST-800, or ISO 27001 can migrate from Pekko v1.0 to Akka 23.05 by obtaining a Lightbend subscription.
Pekko has made commits for their upcoming 1.1 release which breaks API compatibility that could make migrations to Akka difficult. Lightbend will periodically review Pekko SDK additions for incorporation to work around any incompatibilities.
