Pros & Cons
ClickUp
Pros
- Deals can become delivery projects in the same workspace, which suits agencies and consultancies that sell and deliver client work.
- The free plan allows unlimited members and unlimited tasks, so small teams can try the platform before paying.
- Custom fields, task types, many views and automations let teams model most pipelines and processes without code.
- Enterprise security options include SAML, SCIM, audit logs, data residency and HIPAA support with a BAA.
Cons
- It is not a dedicated CRM. Reviewers report needing Zapier automations for CRM workflows, and the CRM page does not confirm email sync or native calling.
- Reviewers report a steep learning curve and say new users need hours of training to become proficient.
- G2 and Capterra reviewers report bugs, slow performance and support replies that do not resolve problems.
- The late-2026 pricing change raised per-user list prices for new workspaces, and heavy AI use requires buying extra credits.
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
