We tried other management tools, but to be honest, the real competition to Slack was Gmail or real-world interruptions.

Project management and communication apps tend to overlap but I find that no one app does all jobs perfectly. Trello and Hive have better Kanban functionality and so serve the "small task within a large project" paradigm better. Slack is by far the better communication tool but …

Trello is a task management tool platform that best complements Slack. Even though you can tag different team members to boards or specific tasks, Slack provides a more robust platform to communicate and share files, ideas, or issues about a task. And can be used as a general …

In comparison to Teams, I think Slack is a much nicer platform to use. If your technology department allows you to integrate third party applications, it can work really well paired with zoom, sharepoint etc. I think for many mid sized businesses it can be a good fit to enhance …
Chose Slack
Slack is a much better product, in my opinion! It’s much easier to use than other products, even though it may be similar enough. I would rather use it than any other product like Slack. Our team loves it and it integrates well with other apps like Asana or gmail.
Chose Slack
Teams always crashes and the 2 steps authentication was really annoying to go through. I liked Google Chat but Slack is more user friendly
Chose Slack
Asana makes project management easy but not the communications. When you're working with remote or global teams, it's necessary to have options in an app to channel work and communicate efficiently.
Chose Slack
I selected Slack because it is the combination of the two that are mentioned above. In ClickUp you can manage the projects and tasks, in Skype you can communicate. Whereas Slack single-handedly handles both of these features, It manages your projects / tasks and allows you to …

Slack's flexibility vs usability is well balanced. Slack does not require a time-sonsuming setup.

Honestly, we did some research and Slack was the one rated the best so we tried that first. We haven't gone back from it.

Before Slack, I used to use Telegram and Whatsapp, but they both were also my personal platform to chat with friends and family. This mix between personal and professional life was very damaging because it felt like I was always working. Slack gave me the possibility to feel …

Slack is better at scaling, better for project management, and better for integrations than everything else we tried, including plain email.

For internal/team communications, Slack is by far the best app I've worked with. The channel system is very simple yet very intuitive. As a result, the app is extremely easy to get familiar with and use daily, even for members of our team who are not very tech-savvy. Slack is …

Slack is better in every way. Slack supports multiple workspaces in a single application. It allows to configure notification of each channels so that you receive messages that you need. Meetings with huddle is pretty awesome where we can have separate space for chat for that …

Slack is just more superior in every way despite certain shortcomings. It is visually pleasing as well.

Slack was so simple to start using--super easy integrations with Jira, Sharepoint/OneDrive, and our PM tools--that it was a no-brainer. The video was glitchy, especially for any users who had iffy upload speeds (which isn't Slack's fault entirely, but they did not have as many …

Simply put, Slack is a much more robust and comprehensive tool.

Whatsapp - Slack is more professional
Chose Slack
Much more customization and ability to organize by topic rather than just by project.
Trello

Trello is the best way to give all of your project ideas and display your thoughts in a stream. Even if this app does not have a calendar, you can still estimate the time [of completion] of your project by adding up the tame it'll take to finish every task. Something that Slack
Chose Trello
Without a doubt, Trello is the easy one of the bunch to use. It is beautiful to look at and easy to interact with. It does for sure lack some features that other software has like Wrike, Basecamp, and Slack. But for simple smooth task management, it is the go-to.
Chose Trello
Trello is another must product for any business like Slack. Both allow a company to have collaborative efforts and increase efficiency which means happier employees and more money for businesses.
Chose Trello
Asana is awesome but it comes with a price. For a startup pricing hurts. ClickUp is so vast and has a lot of areas to get lost in, if you don't set some standards there are many ways to do it wrong. Slack is just a communication platform, you can collaborate and stuff but not …

We actually use both in our company. I personally prefer Slack just because I feel like it gives me more avenues of communication with my peers and coworkers then Trello does.
However, Slack would fail to meet our business requirements for what we need to succeed with new …

Our business ended up using Monday due to the holistic nature of the tool. It allows us to collaborate amongst teams and see the project as a whole easier. Trello is for personal usage and task management. I use Monday to organize my overarching needs, and then put specific …

We found that those software, while they included Kanban boards, offered a lot more features. Our tickets tended to get lost and it was harder to navigate through. Our Product team didn't particularly like how they functioned as much.
Chose Trello
Trello is more simple and not as "robust" as the other tools, but it's easier to use and manage and understand and ACTUALLY get stuff done with. It's simplicity is part of the beauty of using it. You don't need a million options that nobody uses, you just need to get stuff done.
Chose Trello
Trello won becuase of the easy drag and drop feature that makes it simple for team members to jump on and use from day one. That said, Asans has way more features and for a tech-savvy person it would be the choice; it is still user-friendly. While it has a steeper learning …

I have been able to use the free version of Trello for many years and for the free version, this platform offers incredible value. I have not yet found such value in other free versions of similar platforms. This platform is also very easy to use as a first time user.

Trello is more in-depth and task-driven, whereas 15Five is more accountable and has personal weekly goals and accomplishments. Trello can be divided up to allow others to do the listed task, and all employees work together to accomplish and complete each required ticket/card …

I also use Whatsapp chat as a task management tool. Whatsapp group chat is very convenient for assigning tasks and making follow-ups. Trello currently lacks here. Whatsapp chat is also way more handy and user-friendly than Trello, because of its better interface and engagement. …

We do use and like Jura but this can be used with it and we do. It isn’t just Jira light. It’s feature packed but available and understandable to the masses. Anybody can learn this where Jira may take more time. The price is better and it’s just better looking visually honestly.

I selected Trello because even if it's similar to a lot of competitors, it is the cheaper but mainly it is the simplest and quickest software.
Chose Trello
We selected Trello as it was easy to setup...only a few minutes. We looked at MS Planner as part of our Teams integration but that did not have nearly enough labels for our purposes.
Chose Trello
Trello is very easy to use. It is an intuitive software that does not require prior learning to take advantage of it. Asana has a complicated interface, not very intuitive and difficult to use. Trello has an intuitive interface that I like very much.

Chose Trello
Being free and SaaS, it requires very little setup in comparison. It's very simplistic but is just enough.
Chose Trello
Trello is visually more appealing and easier to understand by simply looking at it. When it comes to sharing my board with others, they can quickly (within seconds) see our progress, which gets them excited and buys me more momentum. Asana is great, but it takes a little bit of …
Chose Trello
I would say Trello is very well suited for my team's needs as we are relatively small in size but frequently scale up based on the project's size and needs. We tend to use it at a basic level for organizing internal tasks and to-dos, but also develop large complicated boards …

Trello fills a specific function for simple project tracking. It is better to use this tool as a complement to your workflow instead of a replacement. Anything more complicated should be moved to more adept tools, and communication should be moved to a more focused platform. …

Slack is great for tracking commits to new coding projects. You can take parts of code that still need to be implemented later and easily search through the history of comments if there is something that goes wrong with a code commitment. It can be difficult for people that only like Teams to adjust to a new platform if you are using both to communicate.

For teams or individuals with lots of individual tasks/details to track, Trello is perfect! It basically removes the need for a paper checklist. For those that need an overall project management tool that requires less tasks and more overarching goals, collaboration amongst various teams, and gantt charts I would suggest monday.com

  • Helps track employees "to do before hire", "to do after hired," and "to do when employee leaves"
  • Provides important information on each employee like personal information along with data collected during the time of hire and during employment time
  • Allows more than one person to be assigned to a task per employee and will remain open until everyone involved has completed their task

Cons
Salesforce
  • Would love a better integration with GitHub. For example, notifications when your PR is updated, when review is requested, @-mention in comments, etc.
  • Improved "Later" tab, for example the ability to create to-do lists or making the "Later" tab into a more powerful to-do list (annotate items with notes)
  • More powerful integrations, e.g. Google Calendar could render a calendar view within Slack, rather than sending the daily schedule

To be more transparent, I give 10 because Slack serves our collaboration needs. It provide us a good platform for team communication relaying important update within the company, it has even mobile app where you can install in your phone to monitor any updates within that team that needs your immediate attention and intervention.

I am very likely to renew Trello, because it doesn't cost anything to do so. I am also very likely to use Trello's upgraded features in the future because a lot of my team's data is stored on there and they have already gotten used to the platform. Trello is very easy for new team members to pick up, making the onboarding and usability very streamlined.

Usability
Salesforce
My rating was 7. Its intuitive interface and user-friendly features like channels, threads, and integrations make it excellent for team communication and onboarding. However, its usability is held back by the resource-intensive desktop app and cluttered feeling in large workspaces. The mobile app's performance and unreliable notifications have also been noted as weaknesses.

Trello is incredibly intuitive, both on desktop and mobile right away. It is also full of helpful features that make it even easier to use, and is flexible enough to suit almost any organizational need. Onboarding for the software is thorough, but concise, and the service is frequently updated with even more QOL improvements.

Slack is a soft app, we don't have many issues with it. I recall one or two people complaining about something during our usage period, but I didn't have a bad experience. When the app is slow, usually the problem is with my computer or my internet. The app works just fine.

Whenever I've had to troubleshoot an issue with Slack (which, to be honest, has not happened very often), their online documentation has been easy to locate, easy to understand, and effective in resolving my issue. Slack's ever-growing popularity also means that there's a large community of practice out there that can be depended upon.

I haven't reached out to their support very often and their support is very limited anyway for the free users. They do have tons of great articles and videos in their Help Center and constantly send emails with updates and add-ons to the product. The fact that I've barely ever had to contact their support team means that they've developed a great product.

For our small business, getting a few of us started well on Trello was the key, I think. As long as a couple of us were really comfortable with the interface, we could lead others and help them with any questions. From now on, anyone who works with us just naturally uses Trello for information sharing - it's just part of what we do.

I like Slack better than ClickUp, because I would spend 30-60 minutes a day updating my ClickUp tasks. The way ClickUp was used was very micromanaging. I billed by the hour, so I was willing to put in the time to alert the boss what tasks I was working on.
One of my jobs used Hive - I mostly just ran it in the background in case anyone messaged me. I did not use it often.

  • Trello keeps me organized, focused, and on track. I could filter the Trello board to only see my issues and understand what I needed to work on and when.
  • Trello helped our team implement an agile structure. It's a very simple kanban method of viewing all of your team's tasks and statuses. You can completely customize the columns to your team's specific workflow and create tags relevant to your work.
  • Trello helps reduce unnecessary communications between teams. When I want to request translations, I simply create a card on the localization Trello board -- no need to directly message anyone on the team, and I can watch the status of the card change from "in progress" to "in review" to "translated," all without having to directly ask for updates.
