.dev vs .mobility

.dev is a newer generic top‑level domain aimed at technology and developer audiences, with registration starting at $8.75 per year. .mobility is also a newer gTLD but has a broader, general‑purpose focus, and its price is not publicly listed, making cost comparison difficult. .dev is best suited for sites that want to signal a technical or developer focus, while .mobility may be chosen for projects related to transportation, movement, or broader mobility themes. The main trade‑off is the clear, low‑cost pricing and clear audience association of .dev versus the uncertain pricing and less specific branding of .mobility.
