Is Longhorn or Pi better?

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

Which is cheaper, Longhorn or Pi?

Longhorn starts at Free and Pi at Free.

Does Longhorn or Pi run on more platforms?

Longhorn runs on Linux, Kubernetes. Pi runs on Web, Ios, Android.

Can I use Longhorn for free?

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

What is Longhorn best used for?

Longhorn is most often used for an on-premises kubernetes cluster with local disks and no san that needs replicated persistent volumes, edge sites where shipping a storage array is impractical and three nodes is the whole cluster, a k3s deployment where the storage layer must be light enough to run alongside the workloads, a team that wants snapshots and s3 backups of persistent volumes without paying per-node storage licences. Of those, an on-premises kubernetes cluster with local disks and no san that needs replicated persistent volumes and edge sites where shipping a storage array is impractical and three nodes is the whole cluster are not what Pi is typically brought in for.

What can Longhorn do that Pi cannot?

Longhorn covers Per-volume controllers, Synchronous replication, Snapshots and backups, Volume expansion. Pi covers Conversational AI, Voice mode, Empathetic responses, Multi-platform. Both handle Web interface.

Where each one falls short

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

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

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.

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.
