The short version

  • Only Rook has a free tier, so it costs nothing to try first.
  • Each has a real cost: Rook rook automates Ceph but does not abstract it, so an incident still demands Ceph expertise, and organisations without it end up hiring consultants at exactly the wrong moment.; Sourcegraph enterprise pricing starting at $16k annually creates significant barrier for small teams
  • 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.

Rook

  • A team that already runs Ceph and wants its lifecycle managed declaratively inside Kubernetesnot Sourcegraph
  • A large cluster where three-way replication overhead is unaffordable and erasure coding is requirednot Sourcegraph
  • An organisation building a private cloud that cannot use managed cloud storage services for residency reasonsnot Sourcegraph

Sourcegraph

  • Large-scale code migrations across hundreds of repositoriesnot Rook
  • Enterprise governance and code ownership trackingnot Rook
  • AI-assisted bug hunting and security pattern detectionnot Rook
  • Onboarding engineers into large unfamiliar codebasesnot Rook
  • Regulatory compliance and code audit trailsnot Rook

Where each one falls short

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

Rook

  • Rook automates Ceph but does not abstract it, so an incident still demands Ceph expertise, and organisations without it end up hiring consultants at exactly the wrong moment.
  • There is no vendor and no SLA; the realistic commercial support routes are IBM Red Hat OpenShift Data Foundation or an independent Ceph consultancy, both of which change the cost picture entirely.
  • Ceph is resource hungry, needing substantial memory and dedicated disks per OSD, so the hardware cost of a properly sized cluster is often underestimated.
  • Recovery and rebalancing after a disk or node failure generates heavy background input and output that can degrade application performance for hours, which surprises teams sizing for steady state.
  • Minimum viable clusters require several nodes with several disks each, so it is impractical at small scale and the entry hardware cost exceeds simpler alternatives.

Sourcegraph

  • Enterprise pricing starting at $16k annually creates significant barrier for small teams
  • No free tier or standard plan published; all options require custom sales engagement
  • Complex enterprise-only positioning limits adoption compared to GitHub Copilot's pervasiveness
  • Requires indexing entire codebase; not suitable for small or ephemeral projects

Questions people ask

Is Rook or Sourcegraph better?
Neither clearly leads. Rook starts at Free and Sourcegraph at $16000/year, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Rook or Sourcegraph?
Rook has a free tier; the other does not. Paid plans start at Free for Rook and $16000/year for Sourcegraph.
Does Rook or Sourcegraph run on more platforms?
Rook runs on Linux, Kubernetes. Sourcegraph runs on Cloud, Self-hosted.
Can I use Rook for free?
Yes. Rook has a free tier, so you can try it without paying. Sourcegraph starts at $16000/year.
What is Rook best used for?
Rook is most often used for an on-premises kubernetes platform needing block, shared filesystem and s3 storage without buying three products, a team that already runs ceph and wants its lifecycle managed declaratively inside kubernetes, a large cluster where three-way replication overhead is unaffordable and erasure coding is required, an organisation building a private cloud that cannot use managed cloud storage services for residency reasons. Of those, an on-premises kubernetes platform needing block, shared filesystem and s3 storage without buying three products and a team that already runs ceph and wants its lifecycle managed declaratively inside kubernetes are not what Sourcegraph is typically brought in for.
What can Rook do that Sourcegraph cannot?
Rook covers Ceph operator, Block, file and object, Erasure coding, CSI driver.

Answered from the vendors’ own pages

Rook: Who supports it in production?

Nobody by default. IBM sells Red Hat OpenShift Data Foundation, which is supported Rook and Ceph, and independent consultancies sell Ceph support. Decide this before deployment.

Rook: Does it need Ceph knowledge?

Yes. Rook handles deployment and routine operations, but troubleshooting a degraded cluster is a Ceph skill and there is no way around it.

Rook: Can it replace an object storage appliance?

Functionally yes, through the RADOS gateway, but you take on the operations that an appliance vendor would otherwise carry.
