The short version

  • Only Volnyn has a free tier, so it costs nothing to try first.
  • Each has a real cost: Stacker there is no source export and no self-hosting, so leaving means rebuilding the entire interface and permission model elsewhere, even though the underlying records remain yours.; 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: Stacker covers Per-record permissions, Volnyn covers AI website builder.
  • Prices and features above were last checked on 15 September 2026.

Where each one falls short

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

Stacker

  • There is no source export and no self-hosting, so leaving means rebuilding the entire interface and permission model elsewhere, even though the underlying records remain yours.
  • Performance is bounded by the data source, so an Airtable base near its row limit or an API under rate limiting produces a slow portal that no amount of Stacker configuration will fix.
  • Pricing distinguishes internal editors from external portal users, so a portal that succeeds by adding hundreds of light-touch external users can end up costing more than the internal system it fronts.
  • Custom logic is limited to the actions and conditions the builder exposes, so anything resembling a calculation engine or a branching multi-step approval hits a wall and needs an external automation tool bolted on.
  • It is a portal and CRUD tool by design, with no offline mode, no native mobile application and no real reporting layer, so it will not be the only system a growing operation runs.

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

Stacker: Where does my data live?

In the source you connect: Airtable, Salesforce, HubSpot, Google Sheets or your own Postgres. Stacker reads and writes to it rather than becoming the system of record.

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
Stacker: Can I export the app if I cancel?

No. The data stays in your source system, but the interface, permissions and workflows are Stacker configuration and do not come with you.

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
Stacker: Is it suitable for hundreds of external users?

Technically yes; check the pricing arithmetic first, because external portal users are charged separately and that is where the bill grows.

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
Stacker: Will it replace Airtable?

No, it sits in front of Airtable. If the base itself is at its limits, the fix is moving the data to Postgres rather than changing the portal.

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.
