BUILD LOG
Your build. Followed.
Every post is timestamped, tagged to a vehicle, and threaded into a public build log. Keep a streak going with daily updates, and choose who sees it — public, followers-only, or private.
Now in beta on iOS
Your garage.
Your people.
The streets.
Document your build and get followed. Trade parts that actually fit your garage. Hang out with your scene — clubs, forums, meets — without juggling Instagram, Facebook groups, WhatsApp, and Craigslist.
Five pillars
What the app actually does.
Every feature exists because builders are currently juggling 6 apps to get this done. Spec puts it in one place.
MARKETPLACE
Buy. Sell. Trade. Actually fits.
Every listing is tagged to a specific make, model, and year range. Your garage auto-matches you to parts that fit, with full history and a seller SpecScore.
SCENE
Clubs and forums, not another group chat.
JDM, Euro, Domestic, Track, Stance, Drift — clubs by culture with built-in threaded forums and a club wiki, fully versioned so nothing gets lost.
EVENTS
Meets, shows, and track days — with a real door.
RSVP and see live attendee and car counts, then check in with a scannable pass. Organizers get a door list with arrival counts in real time.
KNOWLEDGE
Wrench knowledge that sticks around.
Tutorials are a first-class post type. Helpful replies earn you a SpecScore. The upvoted answers rise — not buried under 400 comments in a Facebook group.
THE FEED
The streets, for real.
Scene filters, car-culture reactions, and a following feed of the builders you actually care about — not an algorithm guessing.
MARKETPLACE
Parts that actually fit.
Every listing tagged to a make, model, and year range — matched straight against your garage, with a seller SpecScore attached.
SpecScore
See who you're dealing with
before you send money.
Every builder has a SpecScore — a number earned from what they've actually done. Buying a turbo off Craigslist, you know nothing about the seller. On Spec, you see their builds, their helpful answers, their transaction history, and how long they've been in the scene.
It's reputation you earn, not followers you buy.
Why Spec
Built for one thing. Not five things bolted together.
Car people currently juggle Instagram, Facebook groups, WhatsApp, Craigslist, old forums, and Discord — each doing one piece badly. Spec does all of it, together, with fitment that actually works.
