The best Slack apps for your workspace in 2026

Slack has more than 2,600 apps in its app directory. Plenty of them are narrowly useful: for example, Slack’s Vercel app is great if you’re hosting web development projects, but it doesn’t have any appeal outside of that. But most businesses using Slack have the same broad needs: communication, team building, project management, automation, onboarding, and getting work done without lots of context switching.
