Tag Name Validator

Validate a Git tag name and, when requested, check whether it follows a semantic-version pattern. The page separates Git ref errors from release-naming conventions, which helps when a tag is technically legal but does not match an automated release workflow.

What this developer tool does

Validate a Git tag name and, when requested, check whether it follows a semantic-version pattern. The page separates Git ref errors from release-naming conventions, which helps when a tag is technically legal but does not match an automated release workflow.

Applies Git check-ref-format restrictions, then optionally parses a v-prefixed Semantic Version 2.0.0 label.

Annotated and lightweight tags use the same ref-name restrictions. This check does not inspect whether the tag already exists.

Example

The bundled sample demonstrates the expected input. Select Sample, run the analyzer, and compare the detailed output with the summary metrics.

v2.4.0

Use cases

  • Pre-commit and code-review checks
  • Query or repository troubleshooting
  • Generating copy-ready diagnostics for an issue

Tips for reliable output

  • Use the exact text that the target system will receive.
  • Keep dialect- or policy-specific options aligned with your project.
  • Review warnings even when the main result is valid.
  • Save structured JSON when another script needs the findings.
  • Confirm destructive operations in the real environment separately.

Frequently asked questions

What input does the Tag Name Validator accept?

Paste plain text directly into the input box. The parser runs locally in the browser and does not send it to a server.

Can I use the Tag Name Validator with large files?

Moderate source and configuration files work well. Browser memory and algorithm limits may apply to unusually large input.

Does this Tag Name Validator modify my repository or database?

No. It only analyzes or transforms the text you provide and makes no repository or database connection.

Why might the result differ from another tool?

Repository policies, SQL dialects, and parser behavior vary. Treat the result as a focused preflight check and confirm project-specific rules.

Can I download the Tag Name Validator output?

Yes. Run the tool, then use Download for the primary result or the JSON and CSV buttons when structured data is available.
