Pros & Cons
GitHub
Pros
- Projects sits next to issues, pull requests and commits, and items can move to Done automatically when linked pull requests merge.
- Projects is included in every plan, and paid plans start at 4 USD per user per month.
- Table, board and roadmap layouts, with custom and iteration fields, cover basic sprint planning.
- One project can pull issues from multiple repositories.
- The GraphQL API, GitHub Actions and the Marketplace make it highly extensible.
Cons
- There are no built-in burndown, velocity, cumulative flow or cycle-time reports.
- Boards have no WIP limits, and there is no workload or capacity planning.
- Reviewers say it has a steep learning curve and is unfriendly for non-technical stakeholders.
- Projects is limited to 50 fields, and the roadmap view does not handle dependencies or critical paths.
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.
