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.
TeamGantt
Pros

- Exports to CSV, PDF and Microsoft Project, and calendar feeds sync to Google, iCloud and Outlook.
Cons
- No built-in workflow automations, as TechRepublic notes.
- Project caps of 5 to 20 on lower plans mean costs rise as you add projects.
- Documents, wiki and team chat are not built in, so teams rely on other tools.
- Some users report a learning curve and cluttered views on large projects.
