Best Slack apps for small teams in 2026: 10 picks and what they cost
The best Slack apps for a small team are the ones that remove a context switch you make every day. For most teams of 5 to 50 that means a short stack: Google Drive and Google Calendar (or their Microsoft equivalents) for files and meetings, Zoom or Loom for calls and async video, GitHub or Jira for engineering work, Geekbot for standups, Polly for quick polls, Donut for onboarding and team connection, and one AI agent for recurring written work such as weekly updates. Most of these apps are free to install, but Slack Free allows only 10 apps, so choose deliberately. The table below lists what each one does in Slack and what it costs as of October 2026.
Which Slack apps are worth installing in 2026?
| App | What it does in Slack | Price (Oct 2026) | Best for |

How should a small team choose Slack apps?
- Start from a daily annoyance. If people keep asking "is that meeting still on?", install the calendar app. If standups eat 30 minutes, try an async standup tool. Do not install apps because a list told you to, including this one.
- Mind the Free plan limit. Slack Free allows up to 10 apps. Pro ($7.25 per user a month, billed annually) and higher plans allow unlimited app integrations.
- Check who can install. Admins can require approval for apps. Decide who owns app requests so they do not stall.
- Read the permissions. Marketplace listings show what each app can read and post. Prefer apps that only see channels they are invited to.
- Give each noisy app its own channel. Notifications from GitHub, Jira or monitoring tools belong in a dedicated channel, not in #general.
Which apps help with files, calendars and meetings?
Google Drive is the one most Google Workspace teams should install first. Slack's listing says it can create new Docs, Sheets and Slides from Slack, grant the right access automatically when you share a file, and send updates on comments and access requests that you can reply to from Slack.
Google Calendar shows your daily schedule, reminds you before events with a join button for Google Meet, Zoom, Webex or Teams, lets you respond to invites, and can set your Slack status while you are in a meeting (without showing the meeting name).
Zoom lets you start and join meetings from Slack, and with AI Companion enabled it posts meeting summaries with key takeaways and action items afterwards. Loom covers the opposite case: a two-minute recorded walkthrough instead of a meeting. Its Starter plan is free with 25 videos per person and 5-minute recordings.
Which apps help engineering and project work?
GitHub posts issue, pull request, commit, release and deployment activity into channels, groups updates for each pull request in one thread, and lets you create issues from a message. Our GitHub Slack integration guide covers the commands and filters. Jira Cloud now has an @Jira agent that creates and updates work items from plain-language messages, with notifications you can filter to assignments, comments and status changes. If your team sends a sprint summary, see sending a Jira sprint report to Slack.
Both apps are good at events and bad at summaries: they tell you every time something changes, not what the week added up to. Keep them in a dedicated channel and send a weekly summary to the people who do not read that channel.
Which apps help with standups, polls and team culture?
Geekbot runs async standups and check-ins: it asks each person the same questions at a set time and posts the answers to a channel or thread. Its Starter plan is free for teams of up to 10 users with unlimited standups, and Basic is $2.50 per participant a month. For other options, including AI-drafted updates, see AI tools for Slack standups and status updates.
Polly handles polls, surveys and pulse checks. Its Free plan includes unlimited responses with 45 days of results history; paid plans add surveys, standups, scheduling and exports. Donut pairs teammates for intros, runs onboarding journeys and handles shoutouts and celebrations. Its Free plan covers one channel and up to 24 users per round of intros.
One built-in option to consider before adding apps: Slack Workflow Builder covers forms, reminders and simple approvals on paid plans without installing anything.
Do you need an AI agent app in Slack?
Only if your team repeats the same written work every week: status updates, client reports, briefs before calls, or handoffs when someone goes on leave. Slackbot covers some of this on Business+ and Enterprise plans, and shared agents such as Claude Tag, Viktor and OpenTag cover more; our best AI coworkers for Slack compares them, and free AI agents for Slack lists what each free plan includes.
Geniusly is an AI coworker for your team in Slack. It reads the accounts you connect (Gmail, Google Drive, Google Sheets, Slack, GitHub, Linear, and Google Ads) and prepares a brief, report, status update, or handoff for a person to review. Connected apps are read-only by default, except Google Sheets edits you explicitly ask for, and Slack messages beyond its reply are posted only after your approval. Anyone in a channel it has been invited to can ask it for work, it can run a task once, daily, or weekly, and it has a Free plan. It is a narrower tool than a general AI employee, which is the point for a small team: one job, done the same way each week, reviewed by a person. You can get started with Geniusly free.
Frequently asked questions
What are the best free Slack apps?
Google Drive, Google Calendar, Zoom, GitHub and Jira Cloud are free to install (you need an account with each service). Geekbot is free for up to 10 users, and Polly, Donut, Loom and Geniusly have free plans.
How many apps can you install on Slack Free?
Up to 10, according to Slack pricing as of October 2026. Pro, Business+ and Enterprise+ allow unlimited app integrations.
Are Slack apps safe to install?
Apps in the Slack Marketplace show the permissions they request and their security details. Review what an app can read and post, prefer apps that only see channels they are invited to, and use admin approval for app installs.
What is the best Slack app for standups?
For classic async standups, Geekbot is the common choice and is free for up to 10 users. Polly also includes standups on paid plans. If you want the update drafted from your tools rather than typed by each person, an AI agent is the alternative.
What is the best Slack app for productivity?
The calendar and file apps usually save the most time because they remove daily context switches. After that, it depends on your bottleneck: meetings (Zoom, Loom), status updates (Geekbot or an AI agent) or project tracking (GitHub, Jira).
Do Slack apps work on every Slack plan?
Most do, but some features depend on the plan. Workflow Builder needs a paid plan to build workflows, and Slackbot's AI features are fully available on Business+ and Enterprise plans.
