Git Remote URL (SSH) Regex for Python

What this pattern does

This page provides a comprehensive, battle-tested regular expression for matching git remote url (ssh), ported and verified for Python. A rigorously tested regex reduces debugging time and protects your application from edge-case failures. The snippet below is ready to drop into your Python project — whether you're validating in a Django view, a FastAPI endpoint, or a standalone data processing script.

Python Implementation

# Git Remote URL (SSH)
# ReDoS-safe | RegexVault — Dev & Systems > Git

import re

git_remote_url_ssh_pattern = re.compile(r'^git@([a-zA-Z0-9][a-zA-Z0-9\-.]{0,61}[a-zA-Z0-9]):([a-zA-Z0-9_.\-][a-zA-Z0-9_.\-/]{0,253}(?:\.git)?)$')

def validate_git_remote_url_ssh(value: str) -> bool:
    return bool(git_remote_url_ssh_pattern.fullmatch(value))

# Example
print(validate_git_remote_url_ssh("git@github.com:user/repo.git"))  # True

Test Cases

When to use this pattern

This pattern is drawn from the Dev & Systems > Git category and carries a ReDoS-safe certification. That matters for Python developers because particularly important in Python web servers where CPU-bound regex operations can stall concurrent request handling. RegexVault audits patterns against known backtracking attack vectors, ensuring you have the necessary context before using this regex in a high-stakes production environment.

Common Pitfalls

Technical Notes

SSH Git URLs use SCP-like syntax (host:path). Group 1 = hostname, group 2 = repository path. The colon is not a port separator here.
