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.
Upbase
Pros

- The free plan includes unlimited members, tasks, time tracking and chat.
- Profitability tracking by project and client combines time with revenue and cost data.
- Reviewers on G2 and Product Hunt praise the simple, clutter-free interface.
Cons
- Integrations are mostly limited to Google Workspace and a Chrome extension, and the API is listed as in progress.
- Product Hunt reviewers describe the automation and AI features as early-stage.
- The security page names no certifications such as SOC 2 or ISO 27001.
- There are few reviews, and one Product Hunt user reported getting no support reply on a lifetime-deal issue in 2025.
- Custom fields, recurring tasks and the timeline view require a paid plan.
