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.; Volnyn website creation sits on Pro Max, not the entry paid tier, so the feature most buyers arrive for is on the second plan up.
  • They diverge on capability: Corteza covers Corteza Low Code, Volnyn covers AI website builder.

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.

Volnyn

  • Website creation sits on Pro Max, not the entry paid tier, so the feature most buyers arrive for is on the second plan up.
  • Everything is metered from one credit balance, which makes the monthly cost a function of usage rather than a number you can budget. A few AI videos at 100 credits each consume a meaningful share of a Pro allowance.
  • Prices are published in UAE dirhams only, so buyers elsewhere carry the conversion and any card fees on top.
  • The product surface is unusually broad for its size, spanning site building, apps, documents, media generation, browser automation, a freelancer marketplace, a property portal and games. Depth in any one of those is harder to assume than it would be for a focused tool.
  • No founders, leadership or company history are published, and the stated address is a large shared office building, so there is little to verify the operation behind the product against.

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.

Volnyn: Is Volnyn free?

There is a free plan, and it is gated by credits rather than by time. Chat costs 5 credits a message, an AI image 50 and an AI video 100, so the free tier is usable for evaluation rather than for running a site.

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.

Volnyn: What does Volnyn cost?

Pro is AED 33.05 a month or AED 27.43 billed yearly for 5,000 monthly credits. Pro Max is AED 55.09 monthly or AED 45.72 yearly for 7,000 credits and adds AI website creation. Enterprise is AED 146.86 monthly or AED 121.90 yearly for 9,000 credits.

Source
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.

Volnyn: Which plan do I need to build a website?

Pro Max. AI website creation is listed on that tier at 10 credits per website, so the cheapest paid plan does not include the site builder itself.

Source
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.

Volnyn: How do Volnyn credits work?

One balance covers everything. Credits arrive monthly with your plan, roll over if unused, and can be topped up on demand. Each action has a published cost: 5 credits a chat message, 50 an image, 100 a video, 10 a website.

Source
Volnyn: Can Volnyn build mobile apps?

Yes, it lists an app builder covering iOS and Android alongside the website builder, drawing on the same credit balance.

Source
Volnyn: What is the Volnyn browser agent?

A Chrome extension published as Volnyn AI Browser Agent that drives a browser to carry out tasks on your behalf, separate from the site builder.
