Pros & Cons

Orangescrum

Pros

  • Cloud plans charge a flat monthly fee with unlimited users, so costs do not grow with headcount.
  • A self-hosted edition supports on-premises and air-gapped deployment for teams whose data must stay in-house.
  • Reviewers praise detailed time tracking, including billable and non-billable hours, with timesheet approval.
  • Agile tools such as sprints, backlogs and burndown charts sit alongside Gantt charts and critical path analysis.
  • Reviewers on Techjockey rate it highly for value for money (4.9 out of 5).

Cons

  • Reviewers describe the interface as dense, dated or overwhelming, and say beginners need time to learn it.
  • Some users report slowness, bugs, filter problems and slow support.
  • SSO, LDAP and two-factor authentication are only included in Enterprise.
  • The free plan is limited to one user and one project.
  • The vendor does not publish compliance certifications such as SOC 2.

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.
