Drawbacks

• Requires Development Knowledge
  Planby is a developer tool—it’s not a no-code/low-code solution for end users.

• No Built-In Backend or Storage
  Developers must build their own backend logic and data storage system.

• Limited Ecosystem Compared to Commercial Tools
  Lacks built-in analytics, user management, or workflow automation found in platforms like Asana or ClickUp.

• Community-Driven Support
  While active, it lacks the professional support and SLA guarantees of paid software.

Despite these considerations, Planby offers unmatched freedom, control, and value for developers building custom scheduling solutions.

Comparison with Other Tools

Planby fills a specific niche within the scheduling and planning space:

• Versus Full SaaS Tools (e.g., Asana, Trello, ClickUp): Planby is not a standalone product; it’s a component to build your own. Ideal for product teams with internal dev capacity.

• Compared to DHTMLX or FullCalendar: While FullCalendar is event-focused, Planby provides timeline-based Gantt chart visualizations with better React integration.

• Relative to TUI Calendar: Planby offers more modern React/TypeScript support, making it better suited for current web app stacks.

Planby is perfect for teams who need advanced timeline visualizations without heavy external dependencies or cost.
