Text chat
Slack prides itself on delivering efficient communication between teams and individuals via direct messaging and group and company-wide notifications. Users can send private messages to other teammates or message everyone on their channel to ensure that everyone is kept informed.
Channels can be created, renamed, and deleted as needed and you can add topics within a Channel, whether for organizing corporation-wide communication or keeping track of chats with individual clients or friends. The Group Chat feature allows multiple users to chat across timezones and continents whenever mutual decisions and discussions need to occur, ensuring that everyone can register their thoughts, opinions, and even GIFs in real-time.
Discord may have started with gamers as their primary market, but this communications service has expanded to embrace fandoms, communities, and interests of all kinds. Said communities often operate using a forum-like structure with servers being invitation only to avoid users accessing content they may find objectionable.
However, unlike Slack, Discord users must be at least 13 years old to register with the app. While Discord now uses account verification, all other users can see is your avatar and username. You can report users in Discord if their conduct is inappopriate, while chatting is easy with a customizable, user-friendly interface and the ability to search for topics, servers. You can even send and even pin direct messages in Discord directly from the app landing page.
Voice calls
Discord lets users create voice chat servers with a few simple clicks — all you need to do is click the “+” button near voice channels, select Voice Channel, click create, and you’re ready to start sending invitations. It’s also possible to call individuals directly, for one to one communication.
Users have an array of options to customize their audio experiences, including adjustable input and output sensitivity, noise reductions, and echo cancelation, all wrapped up with a microphone settings meter to help you avoid accidentally deafening someone. The app’s highly customizable permission settings determine whether anyone is free to join the conversation or a curated list of select participants with both channel and server-level roles. If you need it, Discord also has a text-to-speech feature.
On Slack, any member of the same workspace can initiate an audio call to another individual. Audio calls are conducted using voice over internet protocols or VoIP, which bypasses the need for traditional phone lines and permit workspace members to speak to each other as needed.
Video chat
Both app’s video chat features can be initiated via a DM with screen-sharing capabilities. However, free Slack accounts are limited to one-on-one participants on a single call, and regular Discord accounts are limited to 10 participants (currently raised to 25, due to current events). Slack and Discord both offer screen sharing, but only Discord offers screen sharing for free.
Paid features and integrations
Both services offer premium packages with enhanced features and services, such as games, streaming, web apps, etc.
Slack plans offer various features, such as extended message history, increased storage capacity, screen sharing, and app integrations.
While Discord only offered text and audio chat features at first, users can now enjoy screen-sharing, video-conferencing, and integration with Spotify, Xbox Live, and Twitch. Discord offers a paid monthly subscription to Discord Nitro, which offers features such as animated avatars, custom emojis, and higher quality Discord screen sharing. Discord Nitro also allows you to upload larger files.
Both apps have iOS and Android versions, as well as desktop and client browsers.
Popularity and audience
The main difference between the two apps is that Discord is specifically geared towards gamers. At the same time, Slack tends to be used by every-day netizens and businesses of varying sizes. Still, each service has much to offer an interested party.
Each service has a respectable user base, with 200 million active monthly users for Discord (2023) and 35 million annual users for Slack (2022). Another similarity between Slack and Discord is the circumstances of their founding by groups of successful financiers who tried and failed to enter the video game market themselves, only to subsequently and independently launch communication apps.
Discord
If you indulge in online gaming even slightly, there’s a pretty good chance you’ve heard of this app. Discord was designed around server-based communications from the get-go and you can find Discord for Xbox Series X and Discord for PlayStation 5 consoles, and for PC.
It currently has at least 6.7 million servers devoted to particular games, game modes, and other sub-topics, making it great for finding existing communities of likeminded individuals. The company’s image suffered considerably when it was discovered that white supremacists and Neo-Nazis used a Discord server to plan the infamous 2017 Charlottesville rally, leading to the implementation of bot-moderation services and account verification tools to prevent such incidents in the future.
Slack
Slack has always envisioned itself as a one-stop-shop for workplace communications by combining email threads, phone and chat services, and virtual meeting spaces, but where it really shines is the staggering 2,500 available apps bots to help you manage and use Slack to its fullest extent.
In case you’re unfamiliar, bots are automated programs that can handle a truly incredible number of tasks — e.g., LunchTrain for privately organizing employee lunches, Trello for approving users and adding cards, Statsbot for analytics updates, metrics management, and report generation — letting you focus on more pressing concerns. You can even create your own custom bots with a little know-how and a decent amount of patience.
Which is best for you?
While both services offer an impressive array of free-to-use communication apps, the sheer disparity of incorporated bots, apps, and integrations makes Slack the clear winner in terms of offering the most flexibility for your group. However, Discord provides a top-rated service that has taken great strides to attract non-gaming interests while originally marketed and designed towards gamers. While it remains to be seen if Discord will catch up to Slack’s massive library of offerings, all any group really needs are video-conferencing, chat services, and making sure no-one makes another “Leroy Jenkins” joke.
If your friends already use Discord, stick with it and enjoy benefits such as Discord Netflix streaming parties. But if you’re looking to take your group somewhere new, Slack might be the better place to start.
