is-a.dev offers free developer subdomains

This is niche developer infrastructure, but it solves a real problem elegantly: giving indie builders a cleaner identity layer without forcing them to buy a domain first.

• –The GitHub-first registration flow turns DNS changes into auditable, version-controlled requests that developers already understand
• –Documentation spans popular hosts and services, so the project works as a practical onboarding layer rather than just a vanity domain gimmick
• –Manual review plus abuse reporting gives it more trust and namespace hygiene than many fully automated free-subdomain offerings
• –For AI developers, the value is mostly around shipping demos, portfolios, and project landing pages rather than core model or tooling work
