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.

Mattermost

Pros

• Can be fully self-hosted or air-gapped, which suits defense, government and regulated industries
• Enterprise tiers include strong compliance tooling: FIPS 140-3 builds, legal hold, compliance export and granular RBAC
• Playbooks give incident and DevOps teams repeatable checklists with automated triggers inside chat
• Built-in Jira, GitHub and GitLab integrations, plus an open API for custom bots
• Open-source core under MIT and AGPL licenses avoids full vendor lock-in

Cons

• The Boards kanban plugin is in maintenance mode and has been removed from the in-product marketplace
• Since v11 the free Entry plan shows only the last 10,000 messages and Team Edition is capped at 250 users, which drew community criticism
• The vendor publishes no prices, licenses are annual prepaid only, and every server needs its own license
• No Gantt charts, time tracking or project reporting, so it cannot replace a dedicated project management tool
• Self-hosting requires admin time and server upkeep
