Solace PubSub+ plans, side by side
Every published tier in ascending order of price, with the number of features each one lists. An absence here means the record does not itemise it, not that the tier lacks it.

| Solace Cloud | On request | 4 | Priced on request |
| Software Enterprise self-managed | On request | 4 | Priced on request |
| Hardware appliance | On request | 4 | Priced on request |
What each tier adds
The set difference between each tier's feature list and the one beneath it. Where a tier lists nothing new, the vendor has either stopped repeating the inherited list or the tier raises limits rather than adding capability, the record does not distinguish the two, so this page does not either.

What the product covers
The full Solace PubSub+ feature record, grouped as the catalogue groups it. This is the product as a whole; the record does not map every feature onto a specific tier.
Other
- Multi-protocol broker
- Dynamic message routing
- Hardware appliance
- Event Portal
- Guaranteed delivery
- Mission Control
- Topic hierarchies and wildcards
- Kafka and MQ bridging
People bring Solace PubSub+ in for a bank building an event mesh across regions where a java jms application and an mqtt mobile client must share the same topic space, an exchange or trading platform with a latency budget that needs the hardware appliance rather than a software broker, an airline distributing operational events to ground systems, aircraft and partner apis over different protocols, a manufacturer bridging factory mqtt telemetry into an enterprise kafka estate without writing translation services. If that is not the job you are buying for, the alternatives to Solace PubSub+ are worth a look before you commit to a tier.
How that compares in Databases
Too few databases tools in this directory publish a starting price to quote a meaningful median, so the table below is a like-for-like list rather than a ranking.

Before you pay for Solace PubSub+
Three things this page cannot tell you, and all three change the bill. The record carries a price and a billing period but not the unit - per-seat and flat-rate pricing are indistinguishable in this data, so a five-person team may be looking at five times the figure above. It carries no annual rate, so any discount for paying yearly is not something this page can quote. And it carries no trial length.
What it can tell you is the shape of the ladder: 4 tiers between Free and On request, with the jump itemised above. Because there is a free tier, the cheapest way to answer the rest is to use it before paying anything.
Solace PubSub+ runs on linux, docker, kubernetes, cloud, hardware appliance, and is published by Solace Corporation of Ottawa, Ontario, Canada. The full record is on the Solace PubSub+ review, and the rest of the category is under best databases tools.
