// Trello vs Flux
Trello got you started. Flux keeps you shipping.
Trello is the kanban board that defined the category. Flux builds on that foundation with real-time SSE sync, a built-in AI assistant, multi-board views, event-sourced undo, and an MCP server for AI agents. Here is an honest comparison.
| Feature | Flux | Trello |
|---|---|---|
| Real-time sync | SSE - instant push to all clients | Polling - updates on refresh or delay |
| AI assistant | Built-in Gemini integration | Butler automation (rule-based, not AI) |
| Multi-board view | Native cross-board column view | No built-in multi-board view |
| Activity log | Event-sourced with before/after snapshots | Basic activity feed, no undo |
| Undo | One-click undo from activity log | No general undo |
| API | REST + MCP server for AI agents | REST API, no MCP |
| RBAC | 4-tier: owner, admin, member, viewer | Normal and admin, plus board-level |
| Pricing | Free to start, no credit card | Free tier with limits, paid from $5/mo |
| Self-hosting | Self-hostable on your infrastructure | Cloud-only (Atlassian hosted) |
| Power-Up ecosystem | API + MCP for custom integrations | Large Power-Up marketplace |
01 Is Flux a Trello replacement?
+
Flux covers the same kanban workflow as Trello - boards, columns, cards, labels, checklists, comments, and attachments. It adds real-time SSE sync, a built-in AI assistant, multi-board views, event-sourced undo, and an MCP server for AI agents.
02 Can I migrate from Trello to Flux?
+
Flux supports board import. Export your Trello board as JSON and import it into Flux to bring over your columns, cards, and labels.
03 Where is Trello better?
+
Trello has a mature Power-Up ecosystem with hundreds of integrations, a larger user community, and deep Atlassian suite integration (Jira, Confluence). If your team is embedded in the Atlassian stack, Trello has a smoother integration path.
04 Where is Flux better?
+
Flux has real-time SSE sync (no refresh needed), built-in AI assistance, multi-board cross-column views, event-sourced activity with one-click undo, and an MCP server that lets AI agents manage your boards autonomously.
