Pros & Cons
Knack
Pros
- Pricing is by plan, not per user, so apps can be shared with many users or external clients at no extra seat cost.
- Reviewers say non-coders can build relational, feature-rich apps without writing code.
- Front ends include calendars, maps, Kanban boards, charts and dashboards for tracking projects.
- Knack's site lists SOC 2 Type II, HIPAA and GDPR compliance, plus SSO.
- Client and vendor portals with role-based logins are a core use case.
Cons
- It is a general app builder, so project management features such as Gantt charts and time tracking are not ready out of the box.
- Reviewers report slower performance and limited customization on larger, complex apps.
- Users have complained that there is no change log for edits made in the builder.
- A competitor's comparison rates its workflow automation as basic and says it relies on Zapier for many integrations.
- The Starter plan is capped at 3 apps and 20,000 records, and promotional prices rise after 3 months.
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.
