Apps, integrations & Connect
Free tier caps you at 10 integrations and Slack Connect needs every external party on a paid plan — useful collaboration ends up gated behind seat licences on both sides.

Integrations are plain webhooks plus a Bolt-style event router in your repo — Linear, GitHub, Sentry and PagerDuty wire in as 30-line handlers. Cross-org collaboration runs over a shared-channel table you control, not a vendor product you pay both sides of.
