15 Best Slack Apps and Integrations for Your Business

With over 10 million daily active users and more than 750,000 organizations using it every day, Slack has quickly become the favorite communication platform for modern businesses. This popularity is well-earned — Slack offers chats, channels, threads, voice and video calls, ensuring seamless connectivity for everyone. As more teams go remote, Slack stands out as the ultimate tool for smooth collaboration.

In today's digital world, Slack is more than just a messaging app, it's a hub where productivity and innovation meet. Its integration capabilities are shaping the way we work, saving time, improving workflows, and connecting various apps with just a few clicks. The best part is that Slack offers a collaborative ecosystem where everything happens in one place, so you don't have to keep jumping between tabs and windows.

In this article, we'll dive into what Slack apps and integrations are and showcase the 15 best ones, including their key features and pricing. Let's get started!

Slack Apps vs Slack Integrations: What's the Difference?

A Slack app is a handy piece of software based on the Slack API, built to perform specific commands, interact with users, and simplify processes within your Slack workspace. Think of it as a virtual assistant hanging out in your Slack channels, ready to help whenever you need it.

These apps can do all sorts of things, like scheduling and tracking tasks, creating an internal knowledge base, or building your company's org chart right from your Slack data. By taking care of repetitive tasks and making communication smoother, Slack apps save you time and help keep your online workspace organized.

‍Slack integrations allow you to connect other software you use (like Google Calendar, Salesforce, or one of your company's internal tools) to Slack. With over 2500 Slack integrations available, you can customize and enhance your experience with alerts, workflows, and instant access to what you need in just a few clicks.

All apps and integrations can be found in the Slack App Directory, a marketplace similar to App Store for iOS and Google Play for Android. There, you can browse and install the tools your team needs.
