FreeDomain: Free Domain Names for Side Projects and Demos

FreeDomain is an open-source project that lets you register domain names and subdomains for free under several community-operated namespaces. It is not a replacement for a commercial .com domain, but for demos, portfolios, and learning, it removes the annual cost barrier.

What it is

FreeDomain, hosted at github.com/DigitalPlatDev/FreeDomain, is a community project that provides free domain-like names under namespaces it operates. Currently supported extensions include US.KG, DPDNS.ORG, QZZ.IO, XX.KG, and QD.JE. The project's README notes that more extensions may be added in the future, though this is not a guaranteed commitment.

The service is designed for a specific scenario: you have a project running on localhost or deployed to a free hosting tier, and you want a clean public URL to share with others. Instead of buying a domain that costs money every year, you claim a free name under one of FreeDomain's namespaces and point it at your hosting provider using DNS records.

Why it matters

• Removes the cost barrier for demos. Buying a domain typically costs money annually. For a project that is still experimental, that cost may not be justified. FreeDomain lets you publish with a real URL before committing to a paid domain.
• Lower barrier to learning deployment. For people learning to deploy web apps, APIs, or static sites, understanding DNS is part of the process. FreeDomain gives a hands-on way to practice A records, CNAME records, TXT verification, and nameserver configuration.
• Clean URLs for portfolios and hackathons. A URL like yourname.us.kg is more shareable than a long hosting-provider subdomain. This matters for portfolio sites, hackathon demos, and client presentations.
• Practical DNS education. Using FreeDomain requires configuring DNS records, which is a real-world skill. The project's documentation walks through the process, making it a practical learning tool.
• Testing before buying. If you are building a product and want to test it publicly before investing in a commercial domain, FreeDomain provides a low-risk intermediate step.

How it works

The setup flow is straightforward. First, you register or log in at the FreeDomain NIC site, such as nic.us.kg. Second, you search for an available name under one of the supported extensions. Third, you configure DNS: either through the built-in DNS provider or by pointing nameservers at a service like Cloudflare. Fourth, you create the appropriate DNS records: an A record pointing at a VPS IP, a CNAME record pointing at Vercel, Netlify, or GitHub Pages, or a TXT record for domain verification. Finally, you wait for DNS propagation, which can take anywhere from a few minutes to a few hours, and test the result.
