The short version

  • Only FaunaDB has a free tier, so it costs nothing to try first.
  • Each has a real cost: FaunaDB the hosted service was wound down in 2025, so there is no managed Fauna to buy; every remaining user either operates a JVM cluster themselves or migrates, and both are projects rather than tasks.; TIBCO Enterprise Message Service the 2026 roadmap is oriented to modernising existing estates rather than winning new deployments, so a greenfield buyer is choosing a product its vendor is not investing in for growth.
  • They diverge on capability: FaunaDB covers Document-relational model, TIBCO Enterprise Message Service covers JMS 2.0 broker.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

FaunaDB

  • The hosted service was wound down in 2025, so there is no managed Fauna to buy; every remaining user either operates a JVM cluster themselves or migrates, and both are projects rather than tasks.
  • The open-sourced repository has had no substantive activity since May 2025 and the drivers were frozen alongside it, so you inherit responsibility for security patches in a Scala distributed database that almost nobody else is running.
  • FQL has no wire or dialect compatibility with anything else, so migrating off is a rewrite of every query, index and access rule in the application rather than a data export.
  • No BI tool, ORM or CDC connector speaks FQL, so reporting and analytics always required exporting the data first, and that export tooling is now also unmaintained.
  • The community was small before the shutdown and has dispersed since, so operational answers, tuning advice and people who have run a Fauna cluster in anger are all scarce when something breaks.

TIBCO Enterprise Message Service

  • The 2026 roadmap is oriented to modernising existing estates rather than winning new deployments, so a greenfield buyer is choosing a product its vendor is not investing in for growth.
  • Nothing is published on price, licensing is per server or per core, and renewal pricing across the Cloud Software Group portfolio has risen sharply since the 2022 Citrix and TIBCO combination.
  • It is a JMS broker, not a durable event log, so replay, stream reprocessing and long retention patterns require Kafka alongside it rather than instead of it.
  • Skills are concentrated in a contractor market that is ageing, and hiring engineers who want to work on EMS is materially harder than hiring for Kafka.
  • Deep integration with the rest of the TIBCO stack, particularly BusinessWorks, makes partial migration difficult; teams commonly find that leaving EMS means replacing several products at once.

Questions people ask

Is FaunaDB or TIBCO Enterprise Message Service better?
Neither clearly leads. FaunaDB starts at Free and TIBCO Enterprise Message Service at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, FaunaDB or TIBCO Enterprise Message Service?
FaunaDB has a free tier; the other does not. Paid plans start at Free for FaunaDB and On request for TIBCO Enterprise Message Service.
Does FaunaDB or TIBCO Enterprise Message Service run on more platforms?
FaunaDB runs on Web. TIBCO Enterprise Message Service runs on Linux, Windows, Solaris, AIX, Docker.
Can I use FaunaDB for free?
Yes. FaunaDB has a free tier, so you can try it without paying. TIBCO Enterprise Message Service starts at On request.
What is FaunaDB best used for?
FaunaDB is most often used for keeping an existing fauna-backed application alive on self-hosted infrastructure while a migration is planned and funded, extracting historical data from a fauna dataset that can no longer be reached through the hosted api, studying a production implementation of deterministic distributed transactions, since the full server source is now readable under apache 2.0, forking the engine deliberately, where an organisation has jvm and distributed-systems staff and wants a document-relational store it fully controls. Of those, keeping an existing fauna-backed application alive on self-hosted infrastructure while a migration is planned and funded and extracting historical data from a fauna dataset that can no longer be reached through the hosted api are not what TIBCO Enterprise Message Service is typically brought in for.
What can FaunaDB do that TIBCO Enterprise Message Service cannot?
FaunaDB covers Document-relational model, FQL v10, Distributed ACID transactions, HTTPS access. TIBCO Enterprise Message Service covers JMS 2.0 broker, Fault tolerant pairs, Server routing, Rendezvous and FTL bridging.

Answered from the vendors’ own pages

FaunaDB: Can I still sign up for Fauna as a service?

No. Fauna Inc. wound down the hosted service in 2025 and the company website is no longer serving. The only way to run Fauna now is to build and operate the open-sourced server yourself.

TIBCO Enterprise Message Service: Is TIBCO EMS still supported?

Yes, releases continue under Cloud Software Group, with 10.x versions shipping and FIPS 140-3 compliance added.

FaunaDB: What licence is the open-sourced code under?

Apache 2.0, with the copyright held by a FaunaDB Foundation. That is a permissive OSI licence with no competing-use clause, so you may run it, modify it and even offer it as a service.

TIBCO Enterprise Message Service: What does it cost?

Nothing is published. It is licensed per server or per core with annual maintenance, usually inside a wider TIBCO agreement.

FaunaDB: Is the open source version the same software that ran the cloud?

It is the core database engine. The control plane, billing, dashboard and multi-tenant operational tooling that made it a service are not part of the release, so you are running the engine, not the product.

TIBCO Enterprise Message Service: Should a new project choose EMS?

Rarely. The vendor roadmap targets existing estates, and greenfield event-driven projects generally start with Kafka or a cloud broker.

FaunaDB: What should I migrate to?

There is no drop-in target. Teams that valued the document model with relationships usually land on Postgres with JSONB, and teams that valued the serverless HTTP access pattern usually land on DynamoDB or a managed Postgres with an HTTP driver. Either way the query layer is rewritten.

TIBCO Enterprise Message Service: Can EMS talk to Kafka?

Yes, an EMS transport for Apache Kafka is supported on Linux, which is the usual bridge during modernisation.

FaunaDB: How hard is it to self-host?

It builds as a fat JAR and runs as a multi-node JVM cluster. There is an OPERATING.md, but no supported packaging, no operator, no upstream releases and no support contract, so budget for a distributed-systems engineer, not a container.
