Switching between multiple apps kills productivity. Every time your team jumps from Slack to another tool, focus is lost and valuable time disappears. But what if you could do most of your work directly inside Slack—and boost productivity by up to 340%? The key is choosing the right Slack integrations.
With over 2,500 apps in the Slack App Directory, finding the ones that truly make a difference can be overwhelming—especially for remote teams that need strong collaboration tools without leaving Slack.
This guide cuts through the noise and reveals the TOP 17 free Slack apps that transform Slack from a simple chat tool into a powerful productivity hub—covering everything from help desk ticketing to automated standups.
1. Suptask
Suptask changes Slack conversations into actionable tasks, which is a great way to overcome the inconvenience of traditional ticketing systems.
A process of creating tasks and tracking project progress can be carried out in the same Slack channel where the discussions happen. This seamless integration reduces response times by 25-40%, a finding confirmed by industry research.
One of the advantages of the platform is the creation of tasks from Slack messages; thus it becomes very easy to convert the requests that are made in passing into tracked tickets.
Organizations with distributed teams who have to deal with multiple time-off requests or IT support needs can use Suptask to get all the information they need without changing the context of their work.
2. Slack Forms by Workflow Builder
Workflow Builder, the just-in-time Slack native, turns your Workspace Slack into a mighty automation gadget.
Members of the team can then submit structured requests through custom forms, whether they are scheduling a meeting, reporting an incident, or requesting equipment. The workflow simply directs the submissions to the appropriate Slack channels and team members.
This automation tool is excellent for collecting feedback and standardizing repetitive tasks. Instead of the tedious process of searching through direct messages for project updates, teams can now utilize forms to gather task status reports, which then directly feed into project collaboration workflows.
3. Polly
Polly makes team engagement a breeze, not a hassle, since it's easy to gather feedback right in the Slack conversation.
Organizations that use regular pulse surveys report the employee engagement rate to be 25% higher, according to the research. The app provides support for everything from quick decision-making polls to comprehensive team sentiment surveys.
Remote teams might experience difficulties in maintaining team spirit. Polly is there to help with its anonymous polling features, which uncover the truth of the matter - team morale, project collaboration challenges. The templates for daily standups and retrospectives facilitate distributed teams to be on the same page without the need for an additional video call.
4. Google Calendar for Slack
The Google Calendar integration makes scheduling meetings right into Slack channels the main feature, thus the constant app-switching, which is the main problem of busy teams, is removed. Meeting reminders are delivered as Slack notifications, and other team members can join video calls with just one click from their Slack conversation.
This integration is beneficial when teams are working in different time zones. Based on Atlassian research, teams that are using calendar integrations have decreased the overlapping of meetings by 15-20%.
The automatic Slack status updates are very convenient because they let the members of the team know who their colleagues are who are not free without having to check the external calendars.
5. Notion
The Slack integration of Notion guarantees that necessary project documentation remains accessible within team conversations.
The changes made to project specifications, meeting notes, or decision logs in Notion by team members will push the relevant updates directly to the designated Slack channels.
This link is the main reason why the teams can keep the context at hand, as they do not have to switch between the different knowledge management tools. Product and engineering teams can attach technical specifications directly to Slack discussions, ensuring that everyone stays updated on the project's progress and requirements.
6. Google Drive
Google Drive from Slack is a file management tool that streamlines document collaboration in Slack channels by removing obstacles.
The team members can share files, get notifications, and manage permissions all from the conversation they are having in Slack. This integration was among the top three most installed file-sharing apps according to Slack's 2024 usage report.
The power is particularly evident in co-working cases where members must simultaneously revise documents and discuss changes. In such a setting, you do not see email chains or files shared in different platforms; everything is accessible in the Slack channel, where the project context already exists.
7. Zapier
Zapier is a tool of automation that is the best for Slack, as it links your Slack channels with over 6,000 other apps.
The staff can automate various tasks, such as automatically setting a task in project management software when a specified keyword is found in a Slack message, or simply taking an update from a Google Drive file and posting it into the related channel.
As per Zapier’s report, users cut down around 8 hours per month of work by automating of the routine workflows. For instance, when team members talk about code snippets in Slack, Zapier can make it as a rule to create GitHub issues without wasting any time, assign the tasks to the developers that are most suited to handle them, and keep track of due dates across various project management tools.
8. Simple Poll
Simple Poll keeps decision-making light and easy in Slack conversations. It doesn't offer the features as advanced as those of survey tools, but it is made for fast, on-the-spot polling which is quite catchy for discussion to continue.
Teams employ it for everything from selecting the optimal time for a meeting to choosing what to eat during virtual coffee breaks.
Slack data reveals that 60% of those who respond to a poll participate within an hour, for non-critical decisions.
This makes the app ideal for keeping distributed teams going. The app's simplicity minimizes the time required to switch back and forth between different tasks, and quicker turnaround of agreements can be achieved for day-to-day matters.
9. Standuply
Standuply changes the way that distributed teams have their standups by collecting updates asynchronously and sharing summaries in Slack channels. Instead of forcing everyone into the same time zone for meetings, team members respond to automated prompts at their convenience, and the Slack bot compiles the responses for the entire team.
One client case study showed the time spent on meetings decreased by 30% after the adoption of Standuply. The tool is compatible with several popular project management tools like Jira and Trello, and uses the API to fetch task details and updates to projects for daily reports.
10. Trello
Trello and Slack work together to create a more seamless visual project management experience within team conversations.
The team members can create new tasks, change the status of a card, and get notifications about due dates, all of this without going out of the Slack workspace. The integration is capable of deep linking to special cards, and real-time updates are done via Trello’s webhook system.
For agile teams managing multiple projects, Trello cards can be created directly from Slack messages, thus saving the context while at the same time not letting any go unnoticed. The visual board interface enables teams to view project progress at a glance, even when discussions occur in Slack channels.
11. Donut
Donut remediates the social distance gap in remote work by automatically pairing team members for virtual coffee breaks and casual conversations. Slack bot syncs up colleagues randomly for regular check-ins, thus strengthening the bonds of the tea,m which could be otherwise weakened in distributed work environments.
GitLab claimed a 17% increase in the number of voluntary social chat minutes after they introduced Donut. The instrument keeps the team spirit alive by inviting spontaneous team interactions and thus creating scenarios for the cross-functional relationship building, which happens naturally in physical offices.
12. Geekbot
Geekbot is an asynchronous team communication tool that gathers standup answers through direct conversation with a user and then publishes the report in the Slack channel.
The platform is open to custom report templates, the use of artificial intelligence for the determination of the sentiment of the text, and seamless connections with multiple project management tools.
Engineer and product teams can leverage Geekbot's talents to keep progress records updated across time zones, eliminating the need for synchronous meetings. The instrument’s sentiment analysis helps managers to identify morale issues within the team well before they hinder the team’s productivity or project collaboration.
13. Jira Cloud
The Slack integration of Jira Cloud issue tracking has been embedded into conversations with the development team. Through Slack channels, developers can create, update, and comment on Jira issues, receive notifications about pull requests, and manage project pipelines with visibility across team members.
According to Atlassian, teams using Jira Cloud for Slack can resolve incidents 30% faster as compared to those switching between tools. The integration allows for rich message formatting for issue previews and ensures security by maintaining permission mapping, while task management is made easy.
14. GitHub
GitHub’s official Slack integration posts directly into designated Slack channels all the activities related to the repository, such as commits, pull requests, and issue updates.
Development teams can select notifications by repository, event type, or contributor, ensuring that only relevant members are informed without being overwhelmed by too many notifications.
The integration allows for the close attachment of links to specific commits and pull requests; thus, teams can discuss code changes in Slack conversations without losing context. For agile development teams, this creates the visibility of project progress and facilitates the coordination of releases across distributed teams.
15. Loom
Loom completely revolutionizes how teams share complicated information by giving the option of video messages that are very quickly recorded and shared in Slack channels.
Instead of lengthy written explanations or synchronous calls, team members can record a screen walkthrough or update, which colleagues can then view at any time.
Teams report 25-40% reduction in Slack message volume and fewer follow-up questions after implementing Loom. The integration is compelling for onboarding purposes, when technical concepts are to be explained, or project updates are provided, as these are the cases where visual demonstration is most advantageous.
16. MailClark
MailClark is a combination of different communication channels that are all brought into Slack, where emails, social media messages, and other external communications are directly routed into designated Slack channels. This is especially helpful for small businesses that are managing customer support or sales inquiries across multiple platforms.
The integration works as a proxy that allows team members to respond to the messages of outsiders directly from Slack while at the same time maintaining professional email signatures and routing. Teams can work together to manage shared inboxes without the need to install customer service software.
17. ClickUp
ClickUp’s Slack integration makes it possible to manage the whole process of tasks within team conversations. While other simple project management tools have limitations, ClickUp allows users to manage complex project hierarchies, use custom fields, and do advanced automation without losing the close connection to Slack workflows.
Each platform supports two-way sync comments and statuses of the tasks; that is, the changes made in ClickUp or Slack will be visible in both places.
