Pros & Cons
GitLab
Pros
- Planning, code, CI/CD, and security live in one tool, so issues link directly to merge requests and pipelines.
- Time tracking with estimates and logged time is included on every tier, including Free.
- It can be self-managed or run as single-tenant Dedicated, which suits regulated enterprises.
- Reviewers on G2 and Capterra rate it about 4.5 out of 5 and praise its robust CI/CD and version control.
Cons
- Users who don't write code face a lot of complexity, and reviewers complain about frequent interface changes.
- Ultimate pricing isn't public, and Premium is listed only with annual billing.
- OKRs require Ultimate and are still not ready for production; the global time tracking report is also experimental.
- Users have long complained that epics exist only at the group level.
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.
