What people use each for

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

Corteza

  • An NGO replacing a Salesforce donation that has run out, needing to keep the data model but remove the recurring costnot Redpanda
  • An integrator building a regulated vertical application it intends to resell, requiring a permissive licence it can ship commerciallynot Redpanda

  • Smaller teams wanting streaming without a dedicated platform groupnot Corteza

Where each one falls short

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

Corteza

  • Planet Crust is a small company of roughly a dozen or so people, so the entire commercial support capability behind Corteza is thin and a large deployment can outgrow the vendors ability to respond
  • No pricing is published for Planet Crusts support, hosting or implementation services, so the true running cost of a supported deployment cannot be estimated without a sales conversation
  • The connector ecosystem is small compared with commercial low-code platforms, so integrations with common SaaS tools usually mean writing against the REST API rather than installing something
  • Hiring is hard: almost nobody has Corteza on a CV, so you are training internal developers on a niche platform and you cannot easily replace them
  • The bundled CRM is a starting point rather than a mature product, and teams that expect Salesforce-equivalent sales functionality out of the box will spend months building the gap themselves

Redpanda

  • The community edition is source-available rather than OSI open source, which matters for some procurement
  • Kafka API compatibility is high but not total, and deep ecosystem tools can hit gaps
  • Smaller community than Kafka, so fewer people have solved your problem before
  • Some operational and tiered-storage features are enterprise-only

Answered from the vendors’ own pages

Corteza: Is Corteza the same thing as Crust?

Yes. The project was branded Crust and renamed Corteza in 2019 when Crust Technology donated it to the Commons Conservancy.

Redpanda: Is Redpanda free?

A community edition is free and source-available. Enterprise features and Redpanda Cloud are paid, and the licence is not OSI open source.

Corteza: Who owns the code?

The Commons Conservancy, a Dutch foundation. Planet Crust in Cork is the primary developer and sells commercial services around it.

Redpanda: Can I use my Kafka clients?

Yes. Redpanda implements the Kafka API, so existing clients and most tooling connect without changes.

Corteza: Is there a paid enterprise edition?

No. Corteza is Apache 2.0 with no feature gating. Planet Crust sells support, hosting and development instead of a restricted edition.

Redpanda: Why remove ZooKeeper and the JVM?

Both are significant sources of Kafka’s operational burden — tuning, coordination and failure modes. Removing them is the core of Redpanda’s pitch.

Corteza: Can it genuinely replace Salesforce?

For case management and a straightforward sales pipeline on a self-hosted footprint, yes. For a large sales organisation relying on AppExchange products and a mature ecosystem, no.
