TL;DR: Trello is the best free visual Kanban with Butler automation. RunoSO Kanban links every card to its client, invoice and vault entry so moving to Done can create an invoice in 90s — no tab hunt. Choose Trello for pure boards; choose RunoSO when tasks are the business.
Trello owns simple Kanban with a generous free tier (10 boards), drag-drop, labels, and Butler automation (“when card moved to Done → move checklist → post comment”). But every card that needs client context, invoice or credential forces you to jump to FreshBooks/Notion/1Password. RunoSO Kanban is linked — task → client → project → invoice → vault lives in one view.
Trello Appeal (Why 50M Use It)
- Free tier generous, power-ups (Calendar, Slack, Drive), Butler no-code.
- Great for standalone boards: editorial, personal CRM, sprint.
Fail point: solo operator closes Build landing in Trello, then opens Sheets to log time, then FreshBooks to invoice, then vault to fetch API key — 4 jumps, 6 minutes lost.
RunoSO Kanban Edge — Linked Objects
Tasks live inside a client & project. Card shows assignee, priority (Low/Med/High), streak, due, and linked invoice/vault count. Move Done → check “Create invoice for this project?” — 90s flow from how to create invoice.
| Feature | Trello | RunoSO |
|---|---|---|
| Boards / Lists / Cards | Excellent, unlimited | Kanban + List, per-project |
| Client linking (filter by client) | Manual (board per client) | Native — Acme Corp → 12 tasks |
| Invoice link (card → invoice) | No (Power-Up hack) | Native — invoice linked to project + client |
| Vault link (card → credential) | No | Native — card shows 3 linked secrets |
| Asset / renewal context | No | Domain/SSL/hosting beside board |
| Automation | Butler (powerful) | Streaks + ⌘K + recurring invoices (simpler) |
| Content pipeline Idea→Published | Board workaround | Native Kanban + calendar linked to client |
| Mobile / offline | Excellent iOS/Android | Web PWA, mobile okay |
| Price (solo) | Free (10 boards) / $5 Standard | Free (5 projects) / ₹169 Solo unlimited |
| Deep work cost | 3-4 tool jumps per task | One view, no sync |
Solo Operator Reality — Time Math
Trello: 15 tasks/day × 3 jumps × 2 min = 90 min/day = 7.5 hrs/week context switching. RunoSO linked board = 15 min/day. Founder story: I tracked 18 hrs/mo lost in why I replaced tools.
When Trello Wins (Keep Both)
- You only need visual tasks, already pay for invoicing/vault elsewhere and love Butler.
- Team >10 needs advanced Power-Ups + Enterprise.
- Content pipeline is simple (3 lists).
Keep personal board in Trello, business OS in RunoSO — boundary prevents “where is that API key?” at midnight.
When RunoSO Wins
- Tasks are billable and must become invoices — see how to organize freelance business.
- Credentials per task (deploy key, Stripe test key) — see organize hosting creds.
- Domain renewals per client must surface on board — see domain checklist.
Switch Path (Export → Map → Keep Trello Archive)
- Trello → Board menu → More → Print and export → Export JSON.
- In RunoSO → Projects → New → map Trello lists (
To Do→Backlog,Doing→Active,Done→Completed). - Link first task to client + vault secret, test 1-click copy.
- Keep Trello archive read-only 30 days; measure: does linked board save >30 min/day?
Try linked Kanban on RunoSO features — link task → client → vault in one click.
