Nextcloud apps vs other suite apps
Nextcloud ships with a large catalog of first-party apps, several of which overlap with dedicated tools in your catena software suite (Rocket.Chat, Plane, Outline, Easy!Appointments, EspoCRM). Both can be installed at the same time, but you usually want to pick one app per job so your team is not split across two tools.
This page compares the most common Nextcloud apps to their suite counterparts and recommends which to enable.
Featured Nextcloud apps in this guide
Section titled “Featured Nextcloud apps in this guide”Nextcloud apps live under Apps -> Your apps inside Nextcloud. The ones covered on this page:

How to read this page
Section titled “How to read this page”For each capability:
- Try the Nextcloud app first if the feature is unclear or the use case is light. Lighter footprint, no extra template to deploy, and you can switch to the dedicated suite app later if you outgrow it.
- Use the dedicated suite app when the Nextcloud app’s limits start to bite, or when the capability is core to your team’s daily work and you need more features, speed, or integrations.
- Use both is rarely a good idea. The exceptions are called out explicitly below.
Your operator can pre-enable a starting set during deployment; you can enable or disable any Nextcloud app yourself afterwards from the same screen.
Chat and video calls
Section titled “Chat and video calls”Both can host channels, direct messages, calls, and file sharing. The interesting axes are where they diverge:
| Axis | Nextcloud Talk | Rocket.Chat |
|---|---|---|
| Deployment | Bundled inside Nextcloud, no extra container | Separate template, own database, own domain |
| Designed for | Small teams where chat is a side channel next to files | Larger rosters where chat is the primary collaboration surface |
| Mobile experience | Lives inside the Nextcloud mobile app | Dedicated iOS / Android apps with native push notifications |
| Integrations | Tightly bound to Nextcloud (Files, Calendar, Deck, Contacts, share-from-app) | Marketplace of apps + channel bridges (Telegram, SMS, Matrix, etc.) |
| Customer-facing channels | None | Built-in livechat widget for website support and omnichannel |
| Federation | Federation across Nextcloud servers (Federated Cloud Sharing) | Matrix federation across organizations |
| Identity | Tied to Nextcloud accounts (Nextcloud itself can chain to Keycloak SSO) | First-class Keycloak SSO out of the box |
| Admin granularity | Inherited from Nextcloud’s roles | Per-channel roles, retention policies, audit logs |
Use Nextcloud Talk for small teams (under 10 people) where chat is a side channel next to file collaboration.
Use Rocket.Chat when chat is the primary collaboration surface, when you need a public livechat widget, when you want a polished dedicated mobile app, or when fine-grained admin controls matter.
Use both only during a migration window. Otherwise turn off Talk when Rocket.Chat is your team chat.

Tasks and project management
Section titled “Tasks and project management”| Nextcloud Tasks + Deck | Plane |
|---|---|
| Tasks: simple to-do lists tied to your CalDAV calendar | Issues, cycles, modules, sub-issues, custom fields |
| Deck: kanban boards, lightweight Trello-equivalent | Kanban, list, calendar, gantt, sprints |
| Personal or small-shared lists | Cross-team workspaces, roadmaps, milestones |
| No estimates, no roadmap, no automation | Estimates, automations, GitHub/GitLab links |
Use Nextcloud Tasks for personal to-dos that sync to the same calendar your CalDAV clients see.
Use Nextcloud Deck for small kanban boards (5-10 cards) shared inside a department.
Use Plane for any work tracked across multiple people, sprints, or external dependencies. Plane is the recommended project-management tool in the suite.

Wiki and shared documents
Section titled “Wiki and shared documents”| Nextcloud Collective + Notes | Outline |
|---|---|
| Collective: collaborative wiki backed by Markdown files in a folder | Database-backed wiki, Notion-style pages |
| Notes: per-user note-taking, syncs to mobile via Notes apps | Hierarchical collections, nested docs |
| Lives next to your files (one URL, one login) | Separate domain, Keycloak SSO, faster search |
| Versioning via Nextcloud file history | Built-in revision history, comments, mentions |
Use Nextcloud Collective for low-volume internal pages where everything else lives in Nextcloud already.
Use Nextcloud Notes for personal notes that sync with mobile.
Use Outline for company-wide knowledge bases, onboarding documentation, or anything that needs strong search and a polished reading experience.
Reference: Nextcloud Collectives · Nextcloud Notes · Outline.
Public booking pages
Section titled “Public booking pages”Both let customers book time slots without a Nextcloud account. They differ in deployment shape and team support:
| Axis | Nextcloud Appointments | Easy!Appointments |
|---|---|---|
| Deployment | A Nextcloud app, runs inside Nextcloud | Separate template, own database, own domain |
| Provider model | One Nextcloud user per booking page (up to 10 pages per user) | Many providers, services, locations managed from one dashboard |
| Calendar | Tied to that user’s CalDAV calendar (any CalDAV calendar works) | Per-provider calendars, syncable via ICS |
| Customer flow | Embeddable form; two-way email confirm/cancel via emailed links | Public booking page hosted at the app’s domain; email + SMS reminders |
| Best for | Solo practitioners, freelancers, anyone whose schedule already lives in Nextcloud | Multi-staff businesses (clinics, salons, repair shops) |
| Payments | None | None natively (Stripe via a small bridge in the suite) |
Use Nextcloud Appointments when you are a one-person operation and your calendar already lives in Nextcloud — it is the lightest possible setup, no separate deploy.
Use Easy!Appointments when several staff need their own schedules, when you want a dedicated booking domain, or when you need services / capacity / multi-location modeling.
See How to pick a scheduler for the full decision tree across all booking patterns.
Nextcloud Calendar (the staff CalDAV calendar) is complementary to both — it covers internal calendars and meeting rooms, not customer bookings. See the Nextcloud-only list below.
Reference: Nextcloud Appointments · Easy!Appointments.
Forms and surveys
Section titled “Forms and surveys”The suite does not ship a dedicated forms app, so Nextcloud Forms is the recommended path for any inner-company forms — HR check-ins, event RSVPs, intake questionnaires, internal surveys. Enable it in Nextcloud under Apps -> Your apps.
| Use case | Recommended app |
|---|---|
| Internal forms (HR, RSVPs, surveys, intake) | Nextcloud Forms |
| Form input that triggers a workflow (auto-create CRM contact, send email, post to chat) | n8n Form Trigger node |
| Customer-facing lead capture tied to a sales pipeline | EspoCRM web-to-lead form |
| Document-signing flow | DocuSeal |
For most inner-company needs, Nextcloud Forms is the right answer: results land in a Nextcloud spreadsheet, the form lives at a public or staff-only URL, and you do not need a separate deployment. Reach for n8n only when the form must trigger an automated downstream action.
Reference: Nextcloud Forms · n8n · EspoCRM · DocuSeal.
Contacts and CRM
Section titled “Contacts and CRM”| Nextcloud Contacts | EspoCRM (or Twenty) |
|---|---|
| Personal and shared address books (CardDAV) | Sales pipeline: leads, accounts, opportunities |
| Phone, email, postal address, notes | Activity history, tasks, calls, deals, reports |
| Meant to feed your phone and email client | Meant to track sales motions over time |
Use Nextcloud Contacts for the staff phonebook and shared address books that sync to phones via CardDAV.
Use EspoCRM when you need to track customer relationships, sales opportunities, and activity history. EspoCRM is the default CRM in the suite.
These two are complementary. Run Nextcloud Contacts for the directory, EspoCRM for sales. Avoid duplicating the same person in both unless you have a specific reason.
Reference: Nextcloud Contacts · EspoCRM · Twenty.
Nextcloud Mail is an IMAP/SMTP client, not a mail server. catena does not host email. Nextcloud Mail can connect to your existing email provider (Microsoft 365, Google Workspace, mailbox.org, etc.) so your team reads and sends mail inside Nextcloud.
Reference: Nextcloud Mail.
Nextcloud-only apps worth knowing
Section titled “Nextcloud-only apps worth knowing”These have no direct equivalent in the suite. Enable them in Nextcloud (Apps -> Your apps) when relevant.
- Calendar — staff and shared calendars over CalDAV. The default for internal scheduling, meeting rooms, and team availability.
- Attendance — clock-in / clock-out time tracking. Useful for small businesses that need a simple staff-attendance log without pulling in a full HR / payroll system.
- Memories / Photos — photo timeline and album browser for image files in your Nextcloud. Useful if your business stores a lot of visual assets.
- Bookmarks — shared bookmarks across your team. Useful for curated link collections.
- Polls — quick group polls (date pickers, multiple choice). Lightweight Doodle equivalent.
- News — RSS reader. Niche but solid.
When in doubt, start with the Nextcloud app
Section titled “When in doubt, start with the Nextcloud app”The Nextcloud apps above are free to enable, light on resources, and easy to turn off if they don’t fit. If you are not sure whether your team needs the dedicated suite app, try the Nextcloud version first — for a week or two, with the actual people who will use it. You will quickly know whether it covers the use case or whether the limits start to bite.
If the Nextcloud app is enough, you save a deployment, a domain, and a separate login surface. If it is not enough, the dedicated suite app is one operator request away — and your data on the Nextcloud side stays in place during the switch.
Talk to your operator any time you want to enable, disable, or swap which app handles a given capability. They can adjust the enabled list in one batch.
