Sugar Calendar
Events can finally ask attendees a question at the moment they sign up.
A side-by-side editorial comparison of Celoxis and Ellie Planner — release velocity, themes, recent moves, and the top alternatives to consider.
Celoxis publishes buyer-guide content on a schedule; its releases are elsewhere
Every captured entry is search-targeted content for project management buyers: best-tools round-ups by vertical and company stage, a resource-levelling guide, a dashboards showcase, cyber security project management. Nothing announces a version, feature or change to Celoxis itself. Publication is regular and the topics rotate through segments — startups, telecom, creative teams — in the way a content calendar does.
Ellie opens its task data to outside agents, eight months after its last changelog.
Ellie is a solo-built task and calendar planner spanning web, desktop, iPhone and iPad. After an eight-month gap, the catch-up release lands a real Week Calendar on iPad, Pomodoro sessions started from a task and restored across reloads, Quick Capture as a standalone window on a global shortcut, rich-text task notes with Markdown shortcuts, and MCP/API access in beta. Beneath the headline items sits the unglamorous work: recurring tasks, timezones, rollover, and calendar sync behaviour.

The only product-adjacent signal is which capabilities the content keeps circling: resource levelling in Gantt charts, dashboards, portfolio-level control. That indicates where Celoxis believes it competes — scheduling and resource management for teams that have outgrown a task board — but it is positioning, not evidence of shipping.
Expect the segment rotation to continue producing one round-up per vertical. Anything about the product's own development will need a source other than this feed.

Beneath the headline items sits the unglamorous work: recurring tasks, timezones, rollover, and calendar sync behaviour.
The consistent pattern across four years of releases is reach - Outlook and Google calendars, Slack, Notion, Todoist, iOS widgets - all aimed at making Ellie available wherever work originates. MCP applies that instinct to agents rather than apps, and the release frames it exactly that way. The in-app AI assistant from a year ago put a model inside Ellie; MCP inverts the arrangement and lets an agent the user picks hold the task data instead.
MCP access is explicitly beta and gated behind Power Features, so the open questions are whether it graduates and how it is priced. The entries do not say which clients have been tested against the endpoint.
