Automate GitHub + Trello with GAIA
Move Trello cards automatically when GitHub PRs merge or issues close
Small development teams and indie developers often use Trello for its simple kanban boards and GitHub for source control, but keeping a Trello board up to date with what is actually happening in GitHub is a manual, error-prone process. A card stays in 'In Progress' long after the PR has merged. Cards in 'Ready for Review' have no link back to the actual GitHub PR. The Trello board that started as a live project tracker becomes a stale to-do list that nobody trusts.
GAIA connects GitHub and Trello so the board updates itself as code moves through the development pipeline. When a developer pushes a branch tied to a Trello card, GAIA moves the card to 'In Progress.' When the PR is opened, the card moves to 'In Review' and a GitHub link appears in the card. When the PR merges, the card moves to 'Done' automatically. The board reflects the real state of the project at all times.
This integration is perfect for small product teams, freelancers managing client projects in Trello, and any team that wants the simplicity of Trello with the automation power of a connected engineering workflow. No plugins, no Trello Power-Ups required — GAIA handles the bridge.
5 things you can automate
Everything GAIA can do when GitHub and Trello are connected.
Move Trello cards through lists based on PR status
GAIA maps GitHub PR lifecycle events to Trello list transitions. Opening a PR moves the card to 'Code Review,' a passed CI run moves it to 'Ready to Merge,' and a successful merge moves it to 'Done' — all without the developer touching Trello.
Create Trello cards from GitHub issues
When a new GitHub issue is opened and labeled 'backlog' or 'sprint,' GAIA creates a corresponding Trello card in the configured list with the issue title, description, labels, and a direct link back to the GitHub issue for full context.
Attach pull request links to Trello cards
When a developer opens a PR that references a Trello card ID in the branch name or description, GAIA attaches the PR link to the Trello card as an attachment so reviewers and project managers can jump directly to the code diff from the board.
Close GitHub issues when Trello cards are archived
GAIA also works in reverse: when a Trello card is moved to 'Done' or archived, GAIA can close the linked GitHub issue and post a final comment with the Trello card URL, keeping both tools consistent from either direction.
Daily stale card notifications
GAIA monitors Trello cards in 'In Progress' lists and cross-checks them against GitHub PR activity. Cards with no associated PR activity in the last few days trigger a Trello comment notification reminding the assignee to update the PR or flag a blocker.
How to set it up
Connect GitHub and Trello to GAIA in three steps.
- 1
Connect GitHub and Trello to GAIA
Authenticate your GitHub repositories and Trello workspace in GAIA's integration panel. Select the Trello boards and lists that should receive GitHub-driven updates and configure which repositories to monitor.
- 2
Map GitHub events to Trello list transitions
Define how GitHub events correspond to Trello list movements. Tell GAIA which branch name patterns or PR description formats indicate a card link, and configure the list names that correspond to each stage of your workflow.
- 3
GAIA automates your Trello board from GitHub
GAIA listens for GitHub webhook events and moves, updates, and comments on Trello cards accordingly. Your board becomes a live, accurate reflection of development progress that the whole team — technical and non-technical — can follow.
