Trello Power-Ups

Web

TypeScriptReactTrello API

A pair of open-source Trello Power-Ups that fill gaps in Trello's built-in feature set.

Sums

Totals number-based custom fields across lists or an entire board. Handy for tracking time, costs, or story points without leaving Trello.

Merge Checklists

Combines checklists from multiple cards into one. Originally built to consolidate ingredient lists from recipe cards into a single grocery list.

Built to share

Both are built with React and TypeScript, deployed on Netlify, and available on the Trello Marketplace. Open source with 10+ GitHub stars.
