Fibery

Pros

• Users define their own databases and relations, so a single workspace can replace separate tools for feedback, roadmaps, and wikis.
• Observers and guests are free on every plan, so stakeholders can view and comment without adding paid seats.
• Nine view types, including Gantt with dependencies, Timeline, Calendar, and Map, are built in.
• Reviewers on G2 and Capterra describe support as responsive and hands-on, including help with complex setups.
• Every plan includes AI features and an MCP server, and the vendor says customer data is not used to train AI models.

Cons

• Reviewers most often complain about the steep learning curve, especially for non-technical teammates.
• Teams must model their processes before tracking feels natural, which adds setup overhead.
• Reviewers describe dashboards and charts as less polished than in dedicated tools, and portfolio resource planning is limited.
• SSO and SCIM are available only on Enterprise, which requires at least 25 paid seats.
• Fibery does not list native time tracking or team chat on its features page.

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.
