The short version

  • Each has a real cost: 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.; esbuild deliberately does not type-check TypeScript, only strips types, so tsc still runs separately
  • They diverge on capability: Corteza covers Corteza Low Code, esbuild covers Very fast builds.
  • Prices and features above were last checked on 31 August 2026.

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 esbuild
  • An integrator building a regulated vertical application it intends to resell, requiring a permissive licence it can ship commerciallynot esbuild
  • A mid-size European company that wants one platform for internal applications and a sales pipeline without paying per seat as headcount growsnot esbuild

esbuild

  • Build pipelines where bundle time is the bottlenecknot Corteza
  • Libraries and tools needing a fast, embeddable bundlernot Corteza
  • Replacing slower bundlers where the plugin ecosystem is not needednot 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.

esbuild

  • Deliberately does not type-check TypeScript, only strips types, so tsc still runs separately
  • Plugin API is far narrower than webpack or Rollup, and complex builds hit its limits
  • Code splitting support has historically lagged the more established bundlers
  • Frequently used indirectly through Vite, so direct use is a narrower need than the download numbers suggest

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.

esbuild: Is esbuild free?

Yes, open source under the MIT licence.

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.

esbuild: Does esbuild type-check TypeScript?

No. It strips types for speed and does not check them. Run tsc separately if you need type checking.

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.

esbuild: Do I need esbuild if I use Vite?

You already have it. Vite uses esbuild internally for dependency pre-bundling and transforms.

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.
