Want to get more out of Slack and make collaboration as smooth as butter? Then, start reading to discover the best Slack apps that'll drive your team toward success, without switching tabs anymore.

In recent years, Slack (standing for Searchable Log of All Conversation and Knowledge) has experienced a huge boom in users, mirroring a larger trend where the adoption of collaboration tools saw an increase of 44% after the pandemic began. It says so itself. According to its data, more than 100,000 organizations use Slack to boost collaboration among team members.

No wonder. This communication platform has chats, channels, threads, and video calls that keep your coworkers connected.

But what if it could do more using integrations? Slack connects with plenty of third-party apps that streamline your workspace further when it comes to time tracking, knowledge sharing, project management, etc.

In this guide, we'll talk about some of the best Slack apps that you can use today, highlighting their top features and who they're good for.

What are Slack apps and why use them?

Slack apps are third-party integrations that extend your Slack workspace with additional functionality. They connect your favorite tools directly to Slack, eliminating the need to switch between applications, often using capabilities like Slack’s Events API to power real-time notifications and updates.

Key benefits of using Slack apps include:

• Reduced context switching: Manage tasks, share files, and start meetings without leaving Slack, which is critical given that dependencies on legacy systems can end up consuming 16+ hours weekly for many organizations.

• Streamlined workflows: Centralize team activities in one communication hub.

• Increased productivity: Turn Slack into a more complete work hub for updates, actions, and answers.

And when you need to collaborate beyond your company, teams can use Slack Connect for collaborating with external partners to keep conversations and shared work in the same place.
