the blunt take

Trello is a drag-and-drop kanban board with a decade of polish on top. The board is a weekend. The decade is the problem.

Cards, lists, and drag-and-drop are genuinely buildable solo. But Trello's moat is the integrations ecosystem, the automation engine, the calendar/planner sync, and the "it just works on mobile too" layer — each one a separate week of pain.

or, you know, use one of these.

if building feels spicy
option A
Planka (self-host)
Open-source Trello clone. Docker compose up. Genuinely feature-complete for small teams.
option B
GitHub Projects
Free with your repo, has kanban views, and your devs are already there.
option C
Wekan (self-host)
Another OSS kanban. Meteor-based, ugly, but it works and costs $0.

what'll actually be hard.

est. total: 6 weeks
1 weekend for boards + cards CRUD · 1 week for drag-and-drop that doesn't feel broken · 1 week for real-time multi-user sync · 1 week for automation rules engine · 1 week for calendar/planner integration · 1 week of polish and mobile layout

hard
nightmare
01
easy
Boards, lists, and cards CRUD
Postgres tables + REST endpoints. This is the tutorial project.
02
easy
Card labels, due dates, assignees
More CRUD. A few extra columns. Still easy.
03
medium
Drag-and-drop reordering
dnd-kit handles the UI. The real pain is fractional indexing to avoid re-ordering the whole list on every drop.
04
medium
Real-time multi-user sync
Supabase Realtime gets you 80% there. The other 20% is conflict resolution when two people move the same card.
05
hard
Automation rules engine
"When card is moved to Done, assign to QA and set due date +2 days." Trigger/condition/action trees are a mini workflow engine. Budget a full week.
06
hard
Calendar/planner sync (Google, Outlook)
OAuth per user, bidirectional event sync, timezone math, webhook refresh tokens expiring at 3am. This is where projects go to die.
