Fast and Efficient Team Collaboration App every Company must have

5.0 last month New

Comments: Feedback from the team is the overall experience of using it for collaboration is very smooth and good.

Pros:

I like it a lot because there is practically zero learning curve. The platform is smooth and fast and the features are very intuitive. It is great for collaboration especially for remote team.

Cons:

Except for some problems when uploading videos, there isn't much to complain about this app. I see some people complain that for the free plans, the storage size is too little. But entering into a paid plan isn't that costly either.

Alternatives Considered: Missive, Mattermost and Zoho Cliq

Reasons for Choosing Slack: Slack is a much better app for our use case. And it is very easy for the team members to pick up and use easily without any problems.

Reasons for Switching to Slack: Better features and cost efficiency is the main reasons we chose Slack over the rest.

It's a great Communication tool and the pricing is fair!

5.0 2 months ago New

Comments: We felt that we made the right move by switching to this pro tool. Our communications it's very effective, and there is no mistake in mixing private or personal communications. This helped our team to stay focused and always reply in business mode.

Pros:

We are a marketing agency and have several types of contracts and clients who love fast communications and avoid long email threads. We cannot live without it.

Cons:

We are glad that restrictions for free accounts were removed, which allow new adopters to get to know the tool better and incorporate it into their daily activities.

Alternatives Considered: Workplace from Meta and Google Workspace

Reasons for Choosing Slack: Management was becoming chaotic.

Switched From: Google Chat

Reasons for Switching to Slack: Because having an independent communication application with no need to have an opened browser tab was a great choice. Also, the versatility to move between workspaces is a must.

Slack is a good software, but does not bring something extra to the table.

3.0 last month New

Comments: Overall, I'm happy with Slack. The tool does exactly what it is supposed to do and no more than that. I don't feel the urge to change, but if my colleagues feel the need to switch, then I don't mind either.

Pros:

The best thing about Slack is its convenience. The tool is easily accessible from both desktop and mobile, and as a person that often works remotely, it is a plus that my chats are synced on all my devices. The tool is easy to integrate, and colleagues that are new to the software never have trouble using it

Cons:

Something I personally don't like about the software is the following:In group chats, multiple topics are often discussed at the same time. When I want to reply to a specific thing my college mentions, it will be hidden under the phrase of this person, which makes it easy to overlook my response. In other communication software, show your comment along with the message you are replying to, making it easier not to overlook a message.

Experience after 3 years of useing Slack

5.0 4 months ago

Comments: Slack demonstrates a strong scientific link, particularly when used for internal company communication. Slack is also user-friendly, with an easy-to-use layout and a login interaction with LinkedIn. Furthermore, as compared to other programs, this application is quite light on computers and phones.

Pros:

It is highly handy for this application to combine login with Linkin, which helps to improve connection possibilities while eliminating many redundant login processes. Also, because Slack is cross-platform (desktop, Android, and iOS), everyone in my firm can communicate with one another regardless of device. Furthermore, the possibility to connect to other storage services like Dropbox, Google Drive, GitHub... Slack's free plan allows users to save up to 10,000 messages exchanged by the team, 5GB of storage, and connect up to 5 additional carrier services.

Cons:

The storage of messages only takes place for a short time and it is necessary to update the paid application versions to use more features. This makes the free version quite limited and unpopular for long-term storage of information.

Alternatives Considered: Redmine and Zendesk Suite

Reasons for Choosing Slack: Slack presents more versatility than telegram and is easier to use.

Switched From: Telegram

Reasons for Switching to Slack: I went through all the possible applications to find the most user-friendly channel in my software company. Done Slack clearly shows multi-app friendliness so I chose it.

Slack has become the easiest way to get in touch with your teammates.

5.0 2 months ago New

Comments: There cannot be a better way to communicate among teams than Slack. Slack has made our lifes easier since we have been working from home remotely from different parts of the globe but stay unified and connected with the help of this tool. They also have a mobile app that lets you access all your chats and files on your phone. Its a great tool for every organization.

Pros:

We have been using Slack for almost a year now and all our departments love it. It is a great way to catchup internally within teams or also coordinate with cross functional teams. We use slack for daily followups and project management and task tracking. The IT department of our organization also uses Slack for bug tracking and remote work. Team communication is now just a click away and we feel connected with Slack.

Cons:

Slack has no issues or bugs that we have faced so far. Works like a charm.
