Launched in 2013, Slack didn’t take long to grow into what it is today: a collaboration hub with 10 million daily users sending a whopping one billion messages weekly. Slack is one of the most popular global solutions for team communication, but beyond messaging your coworkers about work (or what’s for lunch), the platform allows you to connect with like-minded tech professionals outside of your company circle through Slack communities.

Hundreds of Slack communities are bringing people get together on the topics that interest them most—and this number only continues to climb. That means plenty of opportunities to meet and chat with others on just about anything tech related, from software development to UX to data science.

If you’re hungry to grow your tech career, you can’t go wrong with Slack communities, which is why we’re covering the most important info you need to get started, plus 22 of the best Slack communities to join for networking, talking code, finding solutions and maybe even landing your next job.

What is Slack?

Slack “brings the right people, information and tools together to get work done” for companies of all industries and sizes. It replaces roadblocks that commonly slow organizational success with solutions like real-time messages, integrated file sharing (e.g., PDFs, images, videos) and voice or video calls.

Slack 101

If you haven’t used Slack before (or need a refresher), read over the following information on basic functions and features to get the most out of your experience off the bat. 

A workspace is a company’s shared hub for team communication. If using Slack for work, your employer will send you an email invitation to become part of its workspace.

Channels are where members communicate in a workspace. Much like online chat rooms, channels are where team collaboration happens. They can be organized by team, project or topic so that users are only involved in the conversations relevant to them. Users can join and leave channels as needed. But while you can join any public channel, you’ll need an invite to join a private channel.

Communities are like workspaces, except instead of connecting team members at a company, they bring together like-minded professionals from across the globe to talk about a certain topic. (And just like workspaces, Slack communities have channels for more targeted conversations.) Many communities are free to join, but some require a monthly, yearly or one-time fee.

Direct messages are private messages for one-on-one conversations. You can DM one person and up to as many people as needed. Unlike channels, these conversations are only searchable by you and other people included in the message.

Benefits of Slack communities

Joining a Slack community puts you in direct contact with other techies that have similar backgrounds, interests, roles, skills and goals. It’s a chance to expand your networking circle from the comfort of your home, favorite coffee shop or wherever (which can also be useful if you tend to avoid in-person networking events).

And because the tech industry requires you to embrace continual learning as languages, technologies and trends are always changing, Slack is a way to learn from others, find and offer solutions to unanswered questions, and build professional relationships and mentorships that can last for years to come.

What makes it different than other social or professional networking sites? For one, there’s far less distraction, which allows for more focused communication—zero ads or news articles filling your feed and competing for your attention.

You also have easy access to every message sent within channels or direct messages—it’s all indexed and searchable. No more scrolling through countless messages to find that one tidbit of information you need, just search by keyword. Another perk? Slack bookmarks any message you want. All you have to do is “star” it.

And if you’re looking for a new job, you may just find one in a Slack community. Because it’s a tech candidate’s market, tech sourcers and recruiters are finding new ways to reach tech talent. This means less time spent on traditional job boards and search engines, more time on platforms like Slack.
