Best Slack Integrations in 2026: Free and Paid Options
Seven Slack integrations compared on what the free plan allows, what the first paid tier costs, and which limit stops a small team first.
Short answer: Make is the best free Slack automation, with 1,000 credits a month and no time limit on its free plan. Zapier is the easier builder, but its free plan stops at 100 tasks a month on two-step Zaps. For task updates in a channel, Asana is free for 2 seats and Trello is free with unlimited Power-Ups per board.
The first limit many teams hit is Slack's own. Free workspaces connect up to 10 apps. Pro removes that cap and costs $8.75 per member a month on monthly billing.

Slack is where many small teams start the day, so the integrations decide what the subscription really costs. The question is rarely whether an app connects.
It is which free limit you hit first: the app count, a task or credit cap, the seat count, or a meeting clock.
We compared seven integrations on their free plans first, then on the cheapest paid tier, in US dollars. Each entry names the limit that changes the decision, so you can tell when a free plan keeps working and when the bill starts.

Make
The free plan with the most room for Slack workflows, and a Slack integration with 46 modules.
- Pricing
- Free: 1,000 credits a month, 15-minute minimum between runs; Core from $9/mo for 10,000 credits.
Best for: Teams that want Slack automation on a free plan and can wait 15 minutes between runs
Pros
- The free plan has no time limit and 1,000 credits a month
- Make's Slack integration lists 46 modules: 7 triggers, 31 actions and 8 searches
- The paid entry tier, Core, starts at $9 a month for 10,000 credits
Cons
- The 15-minute minimum between runs rules out real-time Slack triggers on the free plan
- Credits are a different unit from Zapier's tasks, so comparing the two plans needs a worked example
Zapier
The easiest builder for a Slack alert, with a free tier that a busy channel can use up quickly.
- Pricing
- Free: 100 tasks a month, two-step Zaps only; Professional $19.99/mo billed annually for 750 tasks.
Best for: Teams already on Zapier, or anyone who wants a guided builder over a visual canvas
Pros
- Two-step Zaps on the free plan cover one trigger and one Slack message
- Professional at $19.99 a month billed annually includes 750 tasks
- The next tier, 1,500 tasks, is $39.00 a month billed annually for heavier flows
Cons
- Free allows 100 tasks a month, so a Slack alert on every new lead can use the whole allowance fast
- Multi-step flows are paid only, which pushes most real workflows onto Professional
Asana
Task tracking and Slack in one free plan, until a third seat forces the paid tier.
- Pricing
- Personal free for 2 seats per project and team, Slack included; Starter $10.99 per user/mo billed annually.
Best for: Two-person teams that want task updates posted into Slack
Pros
- Personal lists the Slack integration among its free connections
- Starter adds timeline views, dashboards, automations and forms once the team pays per seat
- Starter billed annually saves $2.50 per user a month against the $13.49 monthly rate
Cons
- Two seats is a small allowance, and the third person moves the whole team to $10.99 per user
- Dashboards and automations, the parts that make Slack alerts useful, sit on the paid tier
Trello
Board-based work with unlimited Power-Ups on the free plan, capped at 10 boards per workspace.
- Pricing
- Free: unlimited Power-Ups per board, up to 10 boards; Standard $5 per user/mo billed annually ($6 monthly).
Best for: Small teams that run work on boards and want Slack to-dos without paying
Pros
- Unlimited Power-Ups per board on Free means a Slack connection never needs a paid tier
- Free includes capturing to-dos from email, Slack and Teams, a direct route from chat to a board
- Standard is $5 per user a month billed annually, or $6 billed monthly
Cons
- The 10-board cap on Free is the limit that forces an upgrade for agencies with a board per client
- Each Power-Up needs its own setup and permissions review before the team relies on it
GitHub
Pull request, issue and deployment events in Slack, on a free GitHub plan with unlimited private repos.
- Pricing
- Free: unlimited public and private repositories, with unlimited collaborators on private repos.
Best for: Engineering teams that want pull request, issue and deploy alerts in one channel
Pros
- The app posts issue and pull request events and handles /github slash commands from Slack
- Workflow runs can be rerun and deployments approved from Slack, not only watched
- Unlimited collaborators on private repos on Free means the alert channel does not add a seat bill
Cons
- A busy repository floods a channel unless you pick the notification types, such as reviews, releases and deployments
- The app supports GitHub.com and Slack.com, with a separate data-residency build for ghe.com and GHES 3.8 and later
Loom
Video updates that land in Slack on the free Starter plan, capped at 25 videos per person.
- Pricing
- Starter free: 25 videos per person, 5-minute screen recordings; Business $18 per user/mo.
Best for: Teams that send short async video updates into Slack and do not need long recordings
Pros
- Slack is included on Starter, the free plan
- Starter allows up to 50 workspace members, so a small team fits on the free tier
- Business is $18 per user a month, and the page says annual billing saves up to 17%
Cons
- 25 videos per person means a daily update uses the full allowance in about five working weeks
- The 5-minute cap cuts off a longer walkthrough, so a demo needs two recordings
Zoom
Meetings started from a Slack channel, with a 40-minute clock on every group call on Basic.
- Pricing
- Basic free: group meetings capped at 40 minutes, 100 participants; Pro $14.16 per user/mo billed annually.
Best for: Teams that start calls from Slack and keep group meetings under 40 minutes
Pros
- Basic allows unlimited meetings and up to 100 participants per meeting
- Pro is the paid tier above Basic, at $14.16 per user a month billed annually
- Basic costs nothing, so a team can start there and move to Pro only when the clock gets in the way
Cons
- The 40-minute group limit ends a standup or workshop mid-call on Basic
- Pro is $16.99 per user a month on monthly billing, $2.83 more than the annual rate
What it is
A Slack integration is an app that posts into a channel, reads a message, or moves records between Slack and another tool, so people stop copying updates by hand. Many connect for free. The cost sits in the automation tool that runs the work, the seat count of the app on the other end, and the Slack plan that decides how many apps you can add.
Why it matters
Slack's free plan is generous for chat and strict for apps. You get 90 days of message history and up to 10 apps. Pro removes the app cap and allows unlimited app integrations.
For a five-person team on Pro, the Slack seats alone cost $43.75 a month before any integration bill.
The stack behind the app matters more than the app itself. A Zap that posts a Slack alert for every invoice is cheap at 50 invoices a month and expensive at 5,000.
Count the tasks, credits or seats before you pick the tool.

The bottom line
Use Make when the free allowance is the goal. Use Zapier when the team already runs it and stays within its task limits. Asana and Trello are the free starts for task updates in a channel.
GitHub covers engineering alerts on a free plan, Loom carries short video updates, and Zoom is the call you start from Slack, with its 40-minute clock.
Pay for Slack Pro only when the 10-app cap blocks the integration you need, and check that cap before you pay for any tool.
