About GitHub Labels Manager

Audit a pasted labels export for duplicates, colours and gaps, then export JSON, CSV or a gh label script. Part of the DevTools Surf developer suite. Browse more tools in the DevOps / CI-CD collection.

Use Cases

• Design a consistent label taxonomy for a new repository before onboarding contributors.
• Audit and clean up label duplication across a GitHub organization's repositories.
• Generate a label import script to apply a standard label set to multiple repos via the GitHub CLI.
• Plan priority and status labels for a sprint-based GitHub Projects workflow.

Tips

• Establish a consistent naming convention (type:bug, priority:high) before creating labels — retroactive renaming requires updating all open issues.
• Use color groups to signal meaning: reds for blockers/bugs, greens for enhancements, blues for documentation, yellows for questions.
• Export your label set as JSON and commit it to the repo so it can be applied to forks or new repos via the GitHub API.

Fun Facts

• GitHub launched issue labels in 2011 with nine default labels (bug, duplicate, enhancement, etc.). These defaults have not changed meaningfully in over a decade.
• The GitHub API allows up to 100 labels per repository — most project management teams use 15-30 labels before the system becomes harder to maintain than it saves.
• GitHub automatically creates labels when a new repository is created — a process that seeds thousands of identically-named 'bug' labels in purple-ish colors across millions of repos.

FAQ

Can I apply labels to an existing repo in bulk?

Export the label configuration as JSON and use the GitHub CLI (gh label create) or the Labels API to apply them. The tool generates the CLI commands alongside the visual editor.

What's the best color scheme for labels?

Use hue families: red for bugs/blockers, green for new features, blue for documentation, yellow/orange for needs-attention states. Avoid colors that are indistinguishable to colorblind users.

How many labels should a repo have?

15-25 is the practical upper limit before cognitive load outweighs benefit. Use scoped prefixes (type:, priority:, status:) rather than many flat labels to keep the list scannable.
