Fibery vs Nimbus
A side-by-side editorial comparison of Fibery and Nimbus — release velocity, themes, recent moves, and the top alternatives to consider.
Fibery vs Nimbus: at a glance
What is Fibery?
Fibery's Custom Apps go GA, completing its turn from work tracker to embedded app platform
Fibery spent the past quarter building and shipping Custom Apps — AI-generated mini-apps buildable inside the platform via Claude, ChatGPT, or MCP. Custom Apps launched publicly in mid-August after two months of experimental iteration. In the same period, Fibery added AI-driven automation creation, a usage dashboard tracking AI and integration consumption, and expanded MCP coverage to rich text editing and direct Custom Apps authoring. The platform is shipping weekly with a mix of headliner features and steady bug fixing.
What is Nimbus?
FuseBase is pivoting into AI app building while its marketing still sells the old portal category.
The feed tracked here is thefusebase.com — the product trades as FuseBase now — and it carries two unrelated streams. The recent half is competitor-alternative SEO (Quip, Google Docs, Notion Sites, Clinked, Moxo) selling the collaboration and client-portal positioning. The product half, all from May and June, is about something else: FuseBase Flow, FuseBase AI Apps, and an AI Coding module for turning ideas into shippable applications.

Fibery's Custom Apps go GA, completing its turn from work tracker to embedded app platform
◆ Current state
Fibery spent the past quarter building and shipping Custom Apps — AI-generated mini-apps buildable inside the platform via Claude, ChatGPT, or MCP. Custom Apps launched publicly in mid-August after two months of experimental iteration. In the same period, Fibery added AI-driven automation creation, a usage dashboard tracking AI and integration consumption, and expanded MCP coverage to rich text editing and direct Custom Apps authoring. The platform is shipping weekly with a mix of headliner features and steady bug fixing.
◆ Where it's heading
Fibery is repositioning from a flexible project tracker into a platform where teams build custom tooling on top of their own data, without leaving the workspace. The Custom Apps launch — AI-generated, embeddable in documents, now on a versioned platform — is the clearest statement of that direction. MCP integration at multiple layers (rich text, apps, automations) shows Fibery making itself a first-class target in AI-native workflows rather than bolting on a chat widget.
◆ Prediction
The next likely move is tying Custom Apps directly into Fibery's automation engine — AI-built apps that trigger and respond to automations — which would close the loop between the platform's two main new capability axes. The breaking platform update to Custom Apps in September signals further architectural changes are coming before the feature stabilizes.
Nimbus
5.0PM
FuseBase is pivoting into AI app building while its marketing still sells the old portal category.
◆ Current state
The feed tracked here is thefusebase.com — the product trades as FuseBase now — and it carries two unrelated streams. The recent half is competitor-alternative SEO (Quip, Google Docs, Notion Sites, Clinked, Moxo) selling the collaboration and client-portal positioning. The product half, all from May and June, is about something else: FuseBase Flow, FuseBase AI Apps, and an AI Coding module for turning ideas into shippable applications.
◆ Where it's heading
The company is moving from a place to store documents and client files toward a place where agents build software, and the Flow launch states it most plainly — phases, slices, reviews and gates imposed on AI-generated projects instead of one overloaded chat. The target is client-facing businesses that want to ship applications without an engineering team. Marketing has not followed the product: every recent post still chases buyers shopping for a Notion or Quip replacement.
◆ Prediction
Expect the next real releases to keep hardening the AI Coding path — more structure around review, stability and deployment — since that is where every product post in this window concentrates. Whether the listicle engine ever repoints at the AI positioning is unresolved; right now the two halves of this feed address different buyers.
