01What it is and who is there

The Slack Marketplace lists apps that work inside Slack, such as bots, workflow tools and integrations. Teams use Slack all day, so a useful app becomes part of daily work. Listing requires a review by Slack. The audience is team members and admins in companies of all sizes.

02Cost and what you actually pay for

Listing terms are set by Slack; check the current Marketplace guidelines. Building the app is your main cost.

03Is it right for you?

It fits products that post to or read from Slack, such as standups, alerts, approvals or AI assistants. It fits poorly for products with no Slack use. Admin approval inside companies can slow adoption.

04Before you start

  • A Slack app built with Slack's APIs.
  • Read the Slack Marketplace guidelines and security requirements.
  • A clear privacy policy and support page.
  • Screenshots and a short demo.

05Step-by-step: how to distribute here

  1. Build the app and test it in your own workspace.
  2. Review it against Slack's Marketplace guidelines.
  3. Submit for review and fix what is flagged.
  4. Write a listing that shows the job in Slack, with screenshots of real messages.
  5. Add an "Add to Slack" button on your site.
  6. Watch which teams install and follow up with admins.

06What to post or submit

Short description:

[Product] [does job] right in Slack. [One-line benefit]. Free for [plan].

07Common mistakes and do-nots

  • Do not request more scopes than you need.
  • Do not post noisy messages users did not ask for.
  • Do not submit before the security requirements are met.

08How to measure it

  • Track installs and active workspaces.
  • Track paid conversions per workspace.
  • A realistic test: two to three months.

09Time budget

  • Before: 20 to 40 hours to build and pass review.
  • Ongoing: 2 to 5 hours a month.
