AppRanks verdict
Generated from live marketplace data — refreshed daily
Postman is a newly-listed Slack app with a limited review volume. It is listed in the Developer Tools category on Slack Marketplace, which AppRanks treats as the canonical taxonomy node for ranking and competitor comparison. no published reviews yet means feature claims are unverified by the wider merchant base. Without a published review base, the only fit-signal available is the developer's own documentation plus the marketplace's listing-quality audit (linked below). The free tier lets you trial the entry feature set without committing a payment method. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical Slack Marketplace listing.
Pros
- +Free tier available — no card required to evaluate

About Postman
How Postman works
Show full descriptionShow less
Postman is an API collaboration platform that simplifies each step of the API lifecycle and streamlines teamwork so you can create better APIs, faster. With 40M+ developers across 500K+ companies, including 98% of the Fortune 500, teams trust Postman. Now with Postman Agent, your team has an Autonomous API Engineer on call — triggered from Slack to run real workflows: testing APIs, investigating issues, opening PRs, and returning verified results your team can immediately review and ship. When you’re troubleshooting and building APIs, it can be tough to share relevant context with your team and also stay in the loop about changes as they happen. With Postman’s app for Slack, you can: - Kick off autonomous API tasks without leaving Slack,— just mention @Postman in any channel to trigger Postman Agent. It spins up a sandboxed environment to run test suites, investigate issues, document APIs, and post back verified results including collections, specs, and pull requests. - Keep your team on top of changes in Postman, with channel notifications that give helpful context, including what changed and a changelog link - Take quick Postman actions without leaving Slack, such as adding a comment or watching or forking a collection. - Get a 200 response faster with support from your team by sharing response links in Slack or Teams, which immediately shows if the response was successful, and if not what kind of error occurred. - Subscribe to updates from API publishers via Slack to stay aware of the latest. - Request access to Postman resources via Slack. If a teammate shares an internal Postman workspace that you don’t have access to, you can request access directly without leaving Slack. Then Postman admins can approve or deny the request directly within Slack. Heads up: AI can make mistakes. Remember to review the code and answers.
