Pros & Cons

Linear logo
Linear

Pros

  • Reviewers repeatedly name the interface as one of the fastest in the category, with interactions that feel instant.
  • The Free plan includes unlimited members, the API and webhooks, and Linear Agent.
  • Built-in AI features include triage routing, MCP access and coding agent sessions.
  • The security page lists SOC 2 Type II and ISO 27001, and a HIPAA BAA is available on request.

Cons

  • The workflow is built for software teams and fits non-engineering use poorly.
  • There is no native time tracking, and G2 reviewers say epic management is weak.
  • Dashboards, SAML and SCIM require the custom-priced Enterprise plan.
  • Some AI features use separate AI credits, so the per-seat price can understate the total cost.

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
