Pros & Cons
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.
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.
