.dev vs .holiday

The .dev extension is a newer generic top‑level domain aimed at technology and developer audiences, with a minimum registration cost of about $8.75 per year. The .holiday extension, also a newer gTLD, targets travel‑related sites and can be registered for as little as $5.66 per year. .dev is best for projects that want to signal a technical focus, while .holiday works well for tourism, event or vacation content. The main trade‑off is the higher price and more niche perception of .dev versus the lower cost but narrower thematic relevance of .holiday.
