What is a Custom App
Only for Pro and Enterprise plans
You can think of a Custom App as a Custom View: it is a way to view and work with data stored inside Fibery — see information, update, delete and add new entities. With AI, you can build Apps that help end users interact with Fibery faster and more easily. Some use cases to spark your imagination:
Custom Form that has steps, allows you to add collection entities right away, hide or show fields based on conditions
Custom calendar view that shows events better
Custom email-like UI to handle incoming requests faster
QA runs tracker
Barcode scanner
Dashboard that represents data in a nice way
An App is just UI — it can't have any server-side logic — but together with Fibery's flexible databases you can build really cool and complex things
Why Custom Apps exist
Every work tool covers about 80% of what you need with pre-built Views. The last 20% is where the pain lives: the stepped intake form, the calendar that shows events your way, the dashboard your CEO actually reads. Until recently, that 20% meant a feature request (and a wait), a workaround, or yet another tool in your stack.
AI changed the economics. Custom UI that used to take a developer weeks now takes a conversation. Your data already lives in Fibery databases — so instead of waiting for us to ship your exact view, you generate it yourself, on top of your own data, in an afternoon.

That said, don't generate code you don't need. If a configured View, a Form, or an automation covers the case — use it. Reach for a Custom App when configuration runs out of road.
How does an App differ from a View
In a nutshell, an App is a special kind of View. You can create it in any Space or in the Private area, move it to another Space, make it a favorite, etc. The main difference is what you can do inside the App. A View is fairly stable and has just a few configuration options, like filters, sorting, etc. An App is unique and you can build hundreds of them to solve very specific problems and use cases that a pre-defined View just can't handle.
A View is configured (you pick a database, set up filters & sorting), an App is generated (you describe it to AI, it's custom code).
Two ways to create Apps: in Fibery or with your own AI tools
Any user can build Apps in the Private section, and any Architect can build an App inside a Space. There are two main ways to create Apps:
In Fibery. You build by talking to an AI agent in a chat panel — prompt, it builds automatically, you preview live, you re-prompt. Check the Build your first custom App guide
With your own AI tools. You can Build Apps via MCP and use the full power of Claude Code, Codex, or other similar tools
Permissions
When a Custom App is built, it only has access to the data the builder had access to at build time — that's the scope baked into the app. What other users see afterward depends on how the app fetches data:
Live data. If the app queries data live each time it's viewed, permissions work like any other View — each user sees only the data they personally have access to.
Stored/fetched data. If the app fetches data once and stores it (a snapshot), it behaves like a static report. Anyone with access to the app sees that stored data, regardless of their own permissions — because it's not checking permissions on each view, just displaying what was saved.
Note that it isn't yet possible to Share or Publish an App. However, if you Publish Space to Web, the App will be visible to everyone, along with all Space content and Views.
How much does it cost to create an App
The honest answer is "we don't really know for sure", since we need to accumulate statistics and see the numbers. From our internal tests it can cost anywhere from $2 to $100, depending on App complexity and the model (Sonnet is cheaper, Opus is way more expensive).
We recommend using Sonnet — it does a good job in most cases and you will save money.
