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.

What is Fibery?

Fibery puts MCP setup in one settings page and speeds up entity views and formulas.

Fibery's November 5 release is quality-of-life: keyboard filters in search, more actions on whiteboard entity cards, faster entity pages and batched formula updates. Fibery MCP now has its own settings page with one-click Claude and ChatGPT connections and ready commands for Claude Code, Codex, Cursor and OpenCode. AI Connectors reached free beta on October 29.

Nimbus vs Fibery: editorial side-by-side

N5.0

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.

F6.3

Fibery puts MCP setup in one settings page and speeds up entity views and formulas.

◆ Current state

Fibery's November 5 release is quality-of-life: keyboard filters in search, more actions on whiteboard entity cards, faster entity pages and batched formula updates. Fibery MCP now has its own settings page with one-click Claude and ChatGPT connections and ready commands for Claude Code, Codex, Cursor and OpenCode. AI Connectors reached free beta on October 29.

◆ Where it's heading

Fibery alternates big AI releases (AI agent, Custom Apps, AI-built integrations) with polish weeks. Making MCP setup a first-class setting shows it expects outside agents to work in Fibery as much as its own.

◆ Prediction

The pricing decision on AI Connectors is due by year end; MCP-based connector creation is still the open item from October.
