Pricing is based on per user, instead there should be a plan for unlimited users, REST APIs requires a token management.

Cross Department Collaboration Must Have

2018-06-24

Quick easy consolidated platform for collaboration and work storage.

Pros

The file management system is super easy to use and understand, just drag and drop your file and everybody has it instantly.

Cons

Single Sign On setups have to be manually setup or created by workspace owners, it would be good to have Google integration from the outset to jump straight into a workspace.

Good for ad-hoc projects, not necessarily for long-term organization

2018-02-24

I don't recommend it for project management, though.

Pros

Integration with external tools makes automation and use within complex workflows a breeze Easy to use Efficient notification control

Cons

Not much granularity in terms of access roles Search feature makes it hard to retrieve information in their context

Easy Team Collaboration

2018-11-15

Excellent team collaboration in an software that's easy to collaborate with.

Pros

Aside from Slack itself, there exists a huge selection of third-party Slack plugins to make the tool more powerful and connected to other services, and a developer-friendly API for custom integration.

Cons

It's rare, but on the few occasions that Slack goes, we may realize we don't even know how to email or use office phones anymore.

Productivity Work Management for Teams

2019-12-12

We moved all of our email conversations to slack and sharing files between the team is a very useful feature. Now slack became a primary tool for our organization.

Pros

Having an option to upload Documents and Sharing with the team along with the search option is time-saving when compared with Emails.

Cons

Third-party Extensions are not available for every project management task and remembering shortcuts for using some extensions or apps is not that flexible.

Good enough for team collaboration

2019-03-12

Free version is fully functional unless you need to keep track of old conversation, the free version only keep recent conversations.

Pros

Integration with third parties, Slack has a very easy way to integrate with other tools compared to other collaboration tools

Cons

I do not like the way that replies to comments are presented, they are hidden from the regular conversation so it is easy to miss comments if you do not follow the thread

Almost a perfect communication tool

2018-12-05

Overall, Slack has been a great tool for outside communication and collaboration. Together with project management tools, our company is complete email-free.

Pros

Everything from creating and reviewing tasks from a third-party app, to sending out recurring questions across your team, Slack plugins can do it all. - Notifications, uploads, and chats happen very quickly and sync very well.

Cons

The web app, the windows app, and the mobile app all require you to manually sign into each organization on each device.

Not sure what all the fuss is about

2019-12-10

Its streamlined UI is appealing to some but not robust enough for our needs.

Pros

Slack offers a lightweight project management/collaboration tool that isn't bogged down by lots of questionably necessary functionality and enables communication between project teams.

Cons

I consider myself fairly savvy when it comes to user interfaces and just haven't found Slack to be particularly intuitive.

Slack - a platform where team communicate and collaborate effectively

2020-04-30

I like the product quite well in terms of messaging, chatting, team management, project management, and management of other tasks.

Pros

Slack can be integrated easily with a lot of third-party applications such as Office 365.

Cons

When you have more number of simultaneous channels, organization and alert mechanism becomes a disturbance for you, so it requires some level of organizing mechanism at the user end. Video calling quality could be improved.
