Frequently asked

Common questions about Codwa Tools

Are these tools really free?

Yes, 100% free with no time limit. No account required, no feature locked behind a subscription, no "upgrade to Pro" nag — open it, use it, done.

Is the data I enter stored or sent to a server?

For tools like the Slug Generator, SERP Preview, Open Graph Preview, Schema Generator, Robots.txt Generator, and Hreflang Generator — everything runs directly in your browser, nothing is sent to our servers at all. For tools that check a URL (like Meta Tag Checker), only the URL you submit is processed to fetch its data, and it isn't stored.

Can I use these for commercial or client work?

Absolutely. Use them for personal projects, client work, or your own business — there are no usage restrictions.

Why did Codwa Studio build free tools like this?

We've personally run into the frustration of SEO tools gatekeeping basic features behind a subscription. Codwa Tools exists so freelancers, developers, and small marketing teams can get work done without a cost barrier.

Will more tools be added?

Yes, this list keeps growing. If there's a tool you'd find useful that isn't here yet, let us know via the contact page.
