Darner from Erik Frey is a simple, lightweight durable message queue that aims for middle ground between Redis and RabbitMQ. Log-structured storage means queues are not limited by RAM, but unlike RabbitMQ, messages are out-of-process.

Built in C++, Darner boasts performance gains and less configuration over Kestrel while supporting the same memcache protocol.
