Pros & Cons
Lucidspark
Pros
- Facilitation tools such as voting, timers, breakout boards and call-to-me suit remote workshops.
- Security credentials are unusually strong for a whiteboard: SOC 2 Type II, ISO 27001/27701/42001, FedRAMP Moderate and IRAP.
- It works closely with Lucidchart, which Enterprise plans bundle, for teams that diagram as well as brainstorm.
- Over 100 integrations, including Jira, Azure DevOps, Asana, Slack, Teams and Zoom.
- The free plan and 9 to 10 USD per user Team pricing keep the cost of entry low.
Cons
- The free plan allows only three editable boards.
- Reviewers often call the paid subscription expensive for individual users.
- The number of features creates a learning curve for new users, and some find sharing permissions confusing.
- There is no native time tracking, resource management or project reporting.
- Reviewers say chart and data tools are weaker than in Lucidchart.
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
