    Easiest way to get everything under one roof.


    Building active communities is really hard.

    I'm a part of a ton of Slack communities but I'm active in only a handful.

    Slack works to its fullest only when it is implemented in a team and everyone's supposed to use it for communication. Slack could/should improve on making the communities on it better by adding relevant features.

    Possibility to be logged on multiple teams, being available at all times on mobile and desktop, and easy to connect with other services.


    I'm pretty happy with Slack, so no cons for now :)

    As a remote designer, this is a must have. I'm always contactable and available. Super easy way to also have quick calls and communicate with other team members on different teams.

    less email


    managing multiple conversations could be easier

    I love using emails less.

    UX Improvement: Having conversation tabs similar to any modern web browser so important conversations don't get lost in the left menu drawer.

    New Feature: Calendar. This would hopefully kill our company's horrific use of Microsoft Outlook once and for all :-)

    Easy to set up, simple to use, awesome for remote teams


    None that I can see

    Transformed the way we deal with freelancers and sped up our communication exponentially. It means that we can have reactive conversations, essentially 'spinning around in the chair and chatting,' when we think of something.

    Chat rooms, privacy, cat gifs


    Consolidate threads

    We use Slack at 99designs for all internal comms and have even implemented a Slack plugin for customers on our site to help manage their design contests. It's a great communication tool, offering the ability to create various chat rooms for different purposes (we have serious ones like #Announcements and silly ones like #dadjokes) and communicate across our international offices. We also recently started using Slack's video chat feature and definitely like it more than Google Hangouts - better connectivity for sure.

  • Pros: 

    I collaborate with multiple organizations and seamlessly integrate apps into the chat function for domain name availability to trello cards.


    Wish they had a better app market to integrate with Slack.

    Overall this product works smoothly and the updates the developer releases are meaningful and truly addresses a lot of the bugs I generally see the week before a release. They true stay on top of the product and make a great interface for user interaction.

    Fully featured yet smooth and fast.

    Very efficient notifications.


    The repeated third party apps integration tips is almost spammy.

    A little more inline tips on text formatting would help

    I use this one everyday, will not be installing the native app for my desktop and I really wish this was available for mobile as well. As a web technology addict, I'd say this is one beautifully made web-app and it totally does what it needs to do. Even better.

    Smooth as silk. Great integrations. Fun to use. Great for comms.


    Multiple Slack channels still not handled super well on desktop.

    Well, it's Slack. You know what it is. It's pretty cool, eh? Still crossing fingers for a smoother Slack desktop experience, but otherwise it's a marvelous thing.

    Different channels, cool integrations with other apps (google analytics, poll etc)


    Thread function could be improved

    It's a great app for chatting with your team (workmates). What I like it has different channels you can create and post relevant chats (like marketing, sales, product dev etc). Also, you can integrate this with other tools like for eg. google analytics and let them send a notification message to a specified channel in case of anomalities etc. Great alternative to skype for business!

    Edward HuI love a good product with great UI/UX

    Make internal communication WAY easier


    I really can't think of any

    Slack is a great communication software that can totally eliminate internal email communications. Also let's not forget about the huge marketplace behind it, which enables insane amount of intergration.

    simple, usable, fast


    sometimes slow code snippets

    This is one of the bast conversation tools I've used personally.

    Fast & simple with a different ways to express your thoughts.

    Fancy code & snippet tools, but sometimes link preview feature can be hell :(

    Easy to use, nice to collaborate with my team!


    I am really satisfied, didn't find anything you could improve!

    Interface, multi-platform, accessibility



    Slack is awesome! Very well thought-out with tons of short cuts, a great API and a pretty robust app directory to enhance the experience in all kinds of ways, some fun, some serious. Definitely integrates with almost all major platforms and the apps for Android and iOS are fantastic as well. No complaints here.

    Interesting concept but I like GroupMe or Sling more


    Not the best way to keep in touch professionally. Used it for one of my last positions and it wasn't user friendly b/w web and app :(

    Interesting concept but the channels can get pretty confusing and there were many miscommunications between our organization because people couldn't use it coherently. Maybe I'll try it again sometime but I need a break.

  • Pros: 

    Slack creates an egaging environment for open conversation.


    I found the channel threads get quite tricky, convos easily get lost.

    Slack also has a lot of good integrations with other softwares make our day-to-day work super easy. The option of free slack also gives the opportunity to connect with people outside of org.

    its incredible good to use , and works flawlessly over different devices


    can be frustrating if channels are large can mean missing out on lots of messages

    great for both work , small teams and even for creating communitys

  • Pros: 

    - Good UX.

    - Perfect for internal-communication in a business.

    - Sharing documents, screenshots, images ect

    - Group messages


    Can't put a finger on it!

    We're a Saas company and we use it every single day for ALL communication. It is just a great tool.

    Simple and intuitive UI.

    Share feedback in real time across teams.

    Reduces communication gaps and improves productivity.



    Ummm, no such cons so far:)

    Saying that Slack will replace email communication channel, wouldn't be an overstatement :)

  • Chad Reid

    Intuitive, with a nice interface.


    Suffers from downtime now and again.

    It's a flashier version of HipChat, but not demonstrably better necessarily. Although I do like how shared Google documents show up in chats.

    I can see what my team is up to in real time and have a history of it.


    Can be distracting if you aren't careful.

    Adding more voice integrations would be amazing.
