Add AppLaunch Compose Checker

[MJDaws0n]

What this adds

Adds AppLaunch Compose Checker to Validation & Parsers.

It matches the repository's contribution requirements:

• Browser-based: analysis runs locally in the browser.
• Direct link: the entry opens the checker itself.
• 100% free: no signup, trial, paywall, or usage limit.

The checker reviews Docker Compose YAML for risky production defaults, exposed ports, likely literal secrets, mutable tags, missing healthchecks, resource limits, dependency readiness, and persistence. Compose contents are not uploaded.

Disclosure

I own AppLaunch and am submitting my own tool. No compensation is involved. AppLaunch also sells managed Docker hosting, but using the checker does not require a purchase.

Hey MJDaws0n! Thanks for your submission! 🚀

To keep awesome-devtools instantly accessible for everyone, all tools must be:

• Browser-based — no downloads or native app installs
• Direct link — goes straight to the tool (not a multi-tool landing page)
• 100% free — no signups, trials, paywalls, or usage limits

Please make sure your PR meets these criteria. It may take some time for your submission to be reviewed — you can occasionally comment with a "bump" to bring more attention to it.

Thanks for contributing! 🙌

CI note: the Dead Links check stopped in actions/checkout before it reached the link check because this pull_request_target workflow refuses fork code by default. The direct tool URL currently returns HTTP 200, and the submission workflow passed on the original commit.
