GitHub Stack Viewer per cc7

🔗 See your entire pull request stack directly in GitHub.

GitHub Stack Viewer adds a visual representation of stacked pull requests directly to GitHub’s pull-request sidebar ✨

It detects relationships between pull requests by following their base and head branches, then displays the complete stack in dependency order. Open, draft, merged, and closed pull requests are clearly identified, while branching stacks are presented as an indented tree.

🔮 Features:

• Displays parent and child pull requests in one compact widget
• Supports linear and branching stacks
• Highlights the pull request currently being viewed
• Shows open, draft, merged, and closed states
• Works with public and private repositories
• Handles GitHub’s client-side navigation
• Contains no advertising or analytics

🔐 Privacy

GitHub Stack Viewer requires a user-provided GitHub personal access token. The token is stored locally in Firefox and sent only to GitHub’s API. A fine-grained token with read-only pull-request access is recommended.

🧠 How it works

Stack detection is based on branch relationships because GitHub does not provide a native stack identifier.

📌 The current version supports stacks within a single repository; cross-fork relationships may not resolve completely.
