Trello's Free plan stops at 10 open boards per Workspace and 250 Butler command runs a month, and Standard only lifts that ceiling to 1,000 runs, with unlimited runs reserved for the $10 per user Premium tier. Because the quota is shared across the whole Workspace, a handful of card-move and due-date rules can exhaust it before the month ends. Self-hosting Wekan, Planka, Vikunja, Kan and Kanboard removes both ceilings: boards are plain rows in your own MongoDB, Postgres or SQLite instance, and rules run as webhooks, REST API calls or Kanboard automatic actions on your own cron schedule instead of metered command runs. Wekan, Planka and Kan can ingest a Trello board JSON export and Vikunja imports through Trello's OAuth flow, so existing boards carry over without being rebuilt by hand.
