Likelihood to Recommend

Nextcloud

Nextcloud is well suited in any collaboration scenario where users wants to share comments and resources as well as organize events or work together.
It is also very well suited for non-profit organizations as it is free to use and very simple even for non-tech users.
I can't imagine scenarios where it might not be appropriate as running requirements are minimal (php, mysql) so even a single user could find benefit to use it as an alternative for basic icloud or gmail use (files with desktop and mobile clients, calendar and address book).

Slack

When there's a team that spans time zones and continents, Slack is the perfect tool for communication & collaboration. It houses a workplace directory, so any employee can be searched for by name. Sending a direct message to any individual in the company is as simple as finding their name, then typing a message & hitting send! Essentially, it's a hub for all communication -- individual, team, and company-wide announcements can be quickly & easily disseminated using Slack.

Pros

Nextcloud

  • File sharing (internal, public or federated).
  • One software, many activities (files, address book, calendar, chat, edit, email) ...
  • Groupware, sharing between users or groups is really easy and finely controlled.
  • Integrations and many apps.

Slack

  • Slack is a solid chat tool that works across a variety of platforms, with a very low barrier for entry: new users can be invited via email, and can use web-based, desktop, or mobile versions of the application.
  • Slack has really captured the zeitgeist of digital culture, including strong support for customizing look and feel (including custom emojis), and a plethora of integrations with popular web-based tools, including Pivotal Tracker and GitHub on the productive side, and Giphy.com on the fun side.
  • Slack continues to refine and improve their product, with new features being rolled out just about every month.
  • Slack offers a great value in their free version of the app, with most of the tool's functionality available for no cost.

Cons

Nextcloud

  • Merge talk and file client apps on mobile devices.
Joseph Costa | TrustRadius Reviewer

Slack

  • The sorting of channels - it's a bit confusing, could be better sorted, it would make it easier to search and make it more agile.
  • Search - It could also improve, it is not bad, but in some cases (rare) it is difficult to find the term that you want.
  • Heavy performance in other operating systems - At least in Linux, Slack seems to do a little more machine performance than when it is used on a computer running Windows.

We've been thoroughly impressed and hence will renew the application for sure as it's meeting and at times exceeding our exceptions in getting things done. A surely shot application that is recommended for a startup, a small company and also very large enterprise and also for multiple open source projects.
Given the points stated, it's a renew for us.

Everything just works. I think the navigation and usability is quite intuitive. I have never had to look up any information or google how to use a feature of Slack (both in the desktop form and on the mobile app). I've never heard any complaints from our other employees either. I have been asked to remind people how to set up reminders, ironically. Although that itself is really simple too (you type "/remind" and then the reminder details).

I never needed support as everything always worked fine. The documentation on Nextcloud website is extensive and clear. The community is very active on the forum and should support you if you don't already find what you are looking for.

I don't need to be very technical to use the Slack or to integrate tools into Slack. Adding an app (integration) is seamless and the platform walks me through the process. I can communicate with my colleagues quickly either with chat or by using the call feature to phone them. If I ever have a product question, I can quickly go to one of our product channels and search for related questions or pose a question that our experts monitor. These features have made me more effective in my day and in managing my customer base

Alternatives Considered

Nextcloud

Even excluding the budget and privacy concerns, we selected Nextcloud for its simplicity of use and the UI is very clear.
It just does what it is supposed to do.
  • No license.
  • Much, much ease of use.
  • Not opening several windows.
  • No un-useful services.
  • No automatic update.
  • Control over data.
  • Open-source software.
  • Integrations.

Slack

Atlassian actually ended up shutting down HipChat and partnering with Slack, but these are areas in which I think Slack outperformed HipChat:
  • Better UX
  • Ability to edit messages once they've been sent
  • More functionalities and integrations with different tools
  • Ability to share channels with other organizations
  • Better mobile app
  • Dark mode

Return on Investment

Nextcloud

  • We do not spend money on software license (unlike Office 365).
  • Very simple maintenance and upgrading.
  • Very simple backup and restore.
Joseph Costa | TrustRadius Reviewer

Slack

  • I believe this has increased productivity amongst the team in that we can get immediate responses to issues and questions, allowing us to have a better continuous flow of work
  • Having an easy to use tool like this speeds up on boarding, as new team members can easily learn. They also will have access to all existing resources within the tool
  • We have been able to customize communication groups to include those appropriate, eliminating unnecessary noise regarding areas not relevant to particular team members.
