Trello?

KINDAYou can build the valuable core, but the established product has meaningful operational complexity. Pick one narrow promise for v1.

BUILD FIRST

One specific customer type and one primary use case
A vertical slice that completes the main job without manual workarounds
Visible limits, review steps, and a fallback when an external dependency fails

LEAVE FOR LATER

Broad third-party integrations
High-scale collaboration, syncing, and permissions
Automation that can cause harm without human review

RESEARCH NOTES

What this tool actually does.

Checked 2026-09-06

Trello is Atlassian's visual Kanban-style collaborative project management tool. Work centers on boards, which contain lists that represent stages, and cards that move across lists toward Done. A card bundles task details: title, description, comments, attachments, checklists, due dates, labels, assignees, and an activity history. Real-time updates sync across web, desktop, and mobile, with offline support. Over 200 Power-Up integrations connect tools like Slack, Google Drive, Figma, Jira, Bitbucket, and Confluence. Built-in automation (Butler) lets users trigger rules, buttons, and scheduled actions. Templates support common workflows. Premium adds timeline, calendar, table, and map views. Pricing tiers include Free, Standard, Premium, and Enterprise.

RESEARCHED BUILD PROMPT

Give this to your coding agent.

Build a focused Kanban project-management app inspired by Trello's core workflow: users create boards for projects, add lists representing stages (e.g., To Do, In Progress, Done), and create cards for tasks. Cards support title, rich description, comments, checklists, due dates, labels, and assignees; dragging a card between lists updates its stage. Users can filter by label/assignee/due date, search cards, view an activity feed per card, and set simple automation rules (e.g., move card when checklist complete, send notification when due date passes). Implement as a web app with React and a backend (Node/Express or Python/FastAPI) plus PostgreSQL; use optimistic UI updates and WebSocket or SSE for real-time multi-user sync. Support auth (email/password or OAuth), drag-and-drop with dnd-kit, and a calendar/timeline view as optional. Include a README covering setup, architecture, and known limitations. Do not copy Trello's branding, exact visual design, Power-Ups marketplace, native mobile apps, enterprise admin dashboards, or advanced automation builder; focus only on the essential board workflow.

Out of scope for v1: enterprise-scale infrastructure, broad integrations, and feature parity with the reference product.
