What is Leantime?

Leantime swaps role ranks for real permissions and syncs with your calendar app.

Leantime moved from 3.10 to 3.14 between October and 10 November. v3.14.0 replaces role-rank checks with specific permission checks across projects, timesheets, users, API keys, to-dos, milestones and sprints, and opens the calendar to plugins; a new CalDAV plugin syncs both ways with Nextcloud, Radicale and Apple Calendar. Earlier releases added mobile push, per-project modules, global search and self-updating plugins.

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.

Leantime vs Nimbus: editorial side-by-side

L5.0

Leantime swaps role ranks for real permissions and syncs with your calendar app.

◆ Current state

Leantime moved from 3.10 to 3.14 between October and 10 November. v3.14.0 replaces role-rank checks with specific permission checks across projects, timesheets, users, API keys, to-dos, milestones and sprints, and opens the calendar to plugins; a new CalDAV plugin syncs both ways with Nextcloud, Radicale and Apple Calendar. Earlier releases added mobile push, per-project modules, global search and self-updating plugins.

◆ Where it's heading

The release cadence is roughly one feature version every two weeks, split between finer access control and a plugin marketplace that carries more functionality. Core changes increasingly exist to give plugins stable hooks, as the calendar rework shows.

◆ Prediction

Expect more marketplace plugins built on the new calendar and permission hooks, and further permission work extending to the remaining modules.

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.
