aftermarket.dev
The secondary market in almost every category runs on data that’s fragmented and badly integrated. Cars, watches, auto parts, phones. A developer-facing business fixing that is a real proposition, and this address states its position precisely.
The .dev extension is reserved for technical use and enforced with HTTPS, which means a site there reads as a developer product before a visitor sees anything else. Paired with aftermarket, the name names both the audience and the market.
It suits a pricing data API, a developer platform for marketplace integrations, a tooling suite for dealers, or the documentation site for resale infrastructure.
One word, a strong technical extension, no hyphen, and a combination nobody would arrive at by accident.
Available now. Enquiries welcome.
