The honest answer
A single-workspace Kanban product is highly buildable. Real-time collaboration, enterprise permissions, automation, offline support, integrations, and years of edge-case polish are what separate an MVP from Trello.
The hard parts
What actually makes this difficult
- Concurrent ordering
- Realtime presence
- Permission edge cases
What you lose
The parts that make the paid product hard to replace
- Enterprise administration
- Large automation ecosystem
- Offline-first clients
People still pay for Trello because mature collaboration; power-ups; cross-device reliability.

Before you start
Trello build questions
Can I vibe code Trello?
Yes. A focused Kanban app is a strong intermediate project when version one targets one workflow and a small number of collaborators.
How should card ordering work?
Use stable sortable positions and transactional updates. Plan for concurrent moves instead of storing only array indexes.
Do I need realtime updates?
Not for the first useful version. Reliable refresh and optimistic local dragging can ship before sockets or presence indicators.
