OSSeva vs. Seventh State
Seventh State is the RabbitMQ team that grew out of Erlang Solutions, now a brand of Erlang Solutions within the Trifork Group. It sells tiered RabbitMQ support, consultancy, training and its own plugins. OSSeva ships patched builds of RabbitMQ 3.8 to 4.x and the Erlang/OTP releases under them, and can run the clusters for you 24/7.
Where OSSeva is stronger
- ✓Patched, signed RabbitMQ 3.8 to 3.13 and 4.0 to 4.2 builds, so an old cluster still receives security fixes
- ✓Patched Erlang/OTP 24, 25 and 26 past community end of life, tested as pairs with the broker
- ✓24/7 managed operations on your infrastructure on the Operate tier, with a 15-minute P1 response
- ✓Patched Kafka 2.8 to 3.9, ZooKeeper, PostgreSQL and Redis under the same contract
Where Seventh State is stronger
- →RabbitMQ is its whole business, and its team built RabbitMQ services within Erlang Solutions
- →Plugins for support customers: DRS for disaster recovery and data salvage, PrioriQ, Q-Spy, SafeConX and RepliQ
- →Four published support packages, from business-hours tickets to 24/7 with a 30-minute response

Why teams choose OSSeva
Patched builds, not only tracking
Seventh State's support tiers include CVE and version-currency tracking that flags patches you need, and it supports legacy 3.x clusters. Its pages do not list patched builds for RabbitMQ releases the community has stopped fixing. OSSeva backports security fixes into RabbitMQ 3.8 to 3.13 and 4.0 to 4.2 and ships signed packages and images, so a cluster held back by mirrored classic queues or a pinned Erlang release keeps passing scans.
The runtime patched with the broker
Each RabbitMQ release runs on a narrow band of Erlang/OTP releases, and OTP 24, 25 and 26 have left community support. OSSeva patches those OTP releases, including the TLS, SSH and crypto applications, and tests each one against the broker that runs on it. For RabbitMQ customers the Erlang/OTP coverage is included.
A team that runs the clusters
Seventh State's packages are built around tickets, response times, risk reports and consultation days. OSSeva's Operate tier puts engineers on 24/7 monitoring of your RabbitMQ clusters on your own infrastructure, with a 15-minute P1 response and a named engineer, and covers Kafka, ZooKeeper and PostgreSQL under the same contract.
Why teams choose Seventh State
RabbitMQ specialists
Seventh State works almost entirely on RabbitMQ. Its team originated in Erlang Solutions, where it built and delivered RabbitMQ services, and it co-launched the RabbitMQ Summit. Its support covers everything from legacy 3.x to the latest releases, with queue topology reviews, policy checks, HA reviews and DR drills on the higher tiers.
Plugins you will not find elsewhere
Support customers get access to Seventh State's plugins: DRS for disaster recovery and data salvage, even from a single surviving node; PrioriQ for message priorities on quorum queues; Q-Spy for inspecting messages without code changes; SafeConX for partition and connection stability; and RepliQ for spreading quorum queue replicas across zones. OSSeva does not sell RabbitMQ plugins.
Clear packages, training and advice
Its four support packages are published with response times, from Essential with an 8-hour response in business hours to Platinum with 24/7 cover and a 30-minute response, and can be extended with training, architecture days and consultation days. It also runs RabbitMQ training labs and advises on Kafka, NATS and Pulsar.

Frequently asked questions
Who is Seventh State?
A RabbitMQ consultancy formed from the RabbitMQ specialists of Erlang Solutions. Its site describes it as a brand name of Erlang Solutions and part of the Trifork Group, and Erlang Solutions' RabbitMQ page says the team was recently rebranded as Seventh State.
What support packages does Seventh State offer?
Four: Essential, with an 8-hour response in business hours and one ticket a month; Standard, with a 4-hour response and unlimited tickets; Standard+, which adds four urgent 24/7 tickets a year with a 30-minute response; and Platinum, with 24/7 cover and a 30-minute response as standard. Add-ons include training, architecture days, consultation days and plugins.
Does Seventh State patch end-of-life RabbitMQ or Erlang/OTP?
Its pages say it supports legacy 3.x deployments and tracks CVEs and end-of-life dates, flagging needed patches. They do not list patched builds for releases the community no longer fixes. If you need security fixes on a version you cannot leave yet, ask for that in writing. OSSeva ships patched RabbitMQ 3.8 to 4.2 and Erlang/OTP 24, 25 and 26 today.
Can we use Seventh State and OSSeva together?
Yes. A common split keeps a RabbitMQ specialist for architecture, plugins and training and uses OSSeva for patched broker and Erlang/OTP builds and for running the clusters.
Which RabbitMQ and Erlang/OTP versions does OSSeva cover?
RabbitMQ 3.8 to 3.13 and the 4.x series, with 4.0 to 4.2 patched past community end of life, and Erlang/OTP 24, 25 and 26 patched past community end of life. Broker and runtime ship as tested pairs.
How does pricing compare?
We do not publish or estimate other vendors' prices. Seventh State sells tiered support packages with optional add-ons. OSSeva prices RabbitMQ per cluster, with Erlang/OTP included. Ask both for a quote against the same list of clusters and versions.
