Pros & Cons
Slack
Pros
- The app ecosystem is very large, and tools such as ClickUp, Notion, HubSpot and Clockify can post updates into channels.
- Slack Connect lets teams work in shared channels with up to 250 outside organizations on paid plans.
- Compliance coverage is broad, including ISO 27001, SOC 2 Type II, FedRAMP Moderate and HIPAA configurability.
- Lists add table and board layouts with assignees, due dates and subtasks, without leaving chat.
- Workflow Builder automates routine requests and approvals without code.
Cons
- There are no native Gantt charts, dependencies, time tracking or portfolio reporting, so Slack doesn't replace a dedicated PM tool.
- Frequent notifications and busy channels can interrupt focus, a common complaint in reviews.
- The free plan keeps only 90 days of message history and allows 10 apps.
- Advanced AI features require Business+ or above, and per-user costs add up as teams grow.
- Reviewers report that finding older messages through search can be difficult.

- Importers for Trello, Jira, GitHub and Asana make it easier to move existing projects in.
Cons
- Storage on the hosted tiers is very small: 10MB on Free and 500MB on Basic.
- The vendor pages do not mention native time tracking, Gantt charts or automation rules.
- Reporting depends on dashboards and CSV exports rather than advanced analytics.
- Some self-hosting users describe it as bloated and clunky out of the box.
