Is Crossplane or Longhorn better?

Neither clearly leads. Crossplane starts at Free and Longhorn at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, Crossplane or Longhorn?

Crossplane starts at Free and Longhorn at Free.

Does Crossplane or Longhorn run on more platforms?

Crossplane runs on Kubernetes, AWS, Azure, GCP. Longhorn runs on Linux, Kubernetes.

Can I use Crossplane for free?

Both have a free tier, so you can try either at no cost before committing.

What is Crossplane best used for?

Crossplane is most often used for building platform-as-a-service offerings for internal teams, creating unified control layers for multi-cloud infrastructure, designing declarative apis for infrastructure provisioning. Of those, building platform-as-a-service offerings for internal teams and creating unified control layers for multi-cloud infrastructure are not what Longhorn is typically brought in for.

What can Crossplane do that Longhorn cannot?

Crossplane covers Kubernetes extension, Custom API building, Resource management anywhere, Declarative interfaces. Longhorn covers Per-volume controllers, Synchronous replication, Snapshots and backups, Volume expansion.

The short version

Each has a real cost: Crossplane requires Kubernetes expertise and infrastructure; Longhorn there is no vendor and no SLA, so a production incident at three in the morning is your own problem unless you buy SUSE Rancher Prime support separately.
They diverge on capability: Crossplane covers Kubernetes extension, Longhorn covers Per-volume controllers.

Provider ecosystem smaller than Terraform

Longhorn

There is no vendor and no SLA, so a production incident at three in the morning is your own problem unless you buy SUSE Rancher Prime support separately.
Synchronous replication across nodes means write latency depends on the slowest replica and the network between nodes, which makes it a poor fit for latency-sensitive databases.
Every replica is a full copy, so three-way replication consumes three times the raw capacity, unlike erasure-coded systems that are far more space efficient.
It is designed for block storage on modest clusters and does not scale to the node counts or throughput that Ceph or a commercial array handles, so growth eventually forces a migration.
Recovery from certain degraded states, such as a volume stuck detaching or replicas failing to rebuild, requires manual intervention and knowledge of Longhorn internals that is not widely held.

Answered from the vendors’ own pages

Crossplane: Is Crossplane free?

Yes, Crossplane is open source and free to use. It requires a Kubernetes cluster but has no licensing costs.

Source

Longhorn: Who do we call when it breaks?

Nobody, unless you buy SUSE Rancher Prime, which includes commercial support for Longhorn. This is the decisive question for production use.

Crossplane: What is Crossplane used for?

Crossplane is used to build control planes and platforms for infrastructure management, enabling platform teams to expose safe APIs to other teams.

Source

Longhorn: How much capacity does replication cost?

Full copies, so three replicas means three times the raw capacity. Budget accordingly rather than assuming erasure coding efficiency.

Longhorn: Is it suitable for production databases?

For modest workloads yes, but synchronous replication adds write latency and high-transaction databases usually want something faster.
