The short version

  • Each has a real cost: Coolify commit history since June 2026 shows one maintainer at 73 commits and a second at 15 with nobody else above one, and the same two people also ship four other coolLabs products, so the project depends on a very small number of individuals.; 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: Coolify covers Git push deployments, Longhorn covers Per-volume controllers.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Coolify

  • Replacing a managed platform bill with a single Hetzner or DigitalOcean instance running a dozen small applicationsnot Longhorn
  • An agency hosting many low-traffic client sites on shared servers with certificates handled automaticallynot Longhorn
  • Self-hosting analytics, databases and internal tools from the one-click catalogue without writing Compose filesnot Longhorn
  • Deploying inside a country or jurisdiction where no managed platform operates a regionnot Longhorn

Longhorn

  • An on-premises Kubernetes cluster with local disks and no SAN that needs replicated persistent volumesnot Coolify
  • Edge sites where shipping a storage array is impractical and three nodes is the whole clusternot Coolify
  • A K3s deployment where the storage layer must be light enough to run alongside the workloadsnot Coolify
  • A team that wants snapshots and S3 backups of persistent volumes without paying per-node storage licencesnot Coolify

Where each one falls short

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

Coolify

  • Commit history since June 2026 shows one maintainer at 73 commits and a second at 15 with nobody else above one, and the same two people also ship four other coolLabs products, so the project depends on a very small number of individuals.
  • Multi-server support is documented as experimental, load balancer configuration is manual, every server must share the same CPU architecture, and moving images between hosts requires you to run your own Docker registry.
  • In self-hosted mode the Coolify machine holds every SSH key and secret with no documented high availability, so the dashboard host is a single point of failure that the paid Cloud tier fixes and self-hosting does not.
  • Scheduled S3 backups cover PostgreSQL, MySQL, MariaDB and MongoDB only, so application persistent volumes are your responsibility and a restore is untested unless you test it yourself.
  • Release cadence is fast enough that six patch versions shipped inside ten days in August 2026 against several hundred open issues, and because instances can update themselves a regression can reach a production host before you have read the changelog.

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.

Questions people ask

Is Coolify or Longhorn better?
Neither clearly leads. Coolify 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, Coolify or Longhorn?
Coolify starts at Free and Longhorn at Free.
Does Coolify or Longhorn run on more platforms?

Can I use Coolify for free?
Both have a free tier, so you can try either at no cost before committing.
What is Coolify best used for?
Coolify is most often used for replacing a managed platform bill with a single hetzner or digitalocean instance running a dozen small applications, an agency hosting many low-traffic client sites on shared servers with certificates handled automatically, self-hosting analytics, databases and internal tools from the one-click catalogue without writing compose files, deploying inside a country or jurisdiction where no managed platform operates a region. Of those, replacing a managed platform bill with a single hetzner or digitalocean instance running a dozen small applications and an agency hosting many low-traffic client sites on shared servers with certificates handled automatically are not what Longhorn is typically brought in for.

Answered from the vendors’ own pages

Coolify: Is anything held back for the paid tier?

No. Coolify Cloud hosts, updates and backs up the dashboard and gives it high availability. Every feature that touches your applications is in the Apache-2.0 build you can run yourself.

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.

Coolify: What does Coolify Cloud cost?

Five US dollars a month connects two servers, and each additional server is three dollars a month, with 20 per cent off for annual billing. You still supply and pay for the servers themselves.

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.

Coolify: Does it back up my application data?

It backs up PostgreSQL, MySQL, MariaDB and MongoDB to S3 on a schedule. Application persistent volumes are not covered, so anything stored outside a managed database needs your own backup plan.

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.

Coolify: Can I run it across several servers?

Yes, but the documentation calls multi-server experimental. Load balancing is not configured for you, all nodes must share a CPU architecture, and you need to run your own Docker registry.
