As answered by people managing Countspace and JSONFormatter.org.
Countspace's answer
Existing countdown tools force you to create one countdown per URL, which fragments any use case with more than one date. Countspace lets you group them — a trip with departure + arrival + return, a wedding with lead-up milestones, a sports season, a launch with pre-orders + release + review windows. One board, one link, one screen.
Countspace's answer
Multiple countdowns stacked on a single shareable board, instead of the usual one-countdown-per-URL sites. Recipients don't need an account to view. Boards open fullscreen on any screen (TV, phone, event monitor) and can be embedded on third-party sites via a separate embed subdomain.

Next.js 15 (App Router), Supabase (Postgres + Row-Level Security + Realtime + Auth), Vercel (hosting + edge middleware), Stripe (payments).
Countspace's answer
Built out of the frustration I kept hitting as a solo maker — I made one-off countdown pages for different things (a trip, a wedding lead-up, event launches) and got tired of hopping between them. I wanted one place I could hand a URL to anyone and open fullscreen on any screen. So I built the app I wanted for myself.
Countspace's answer
Anyone whose life has more than one important date coming up at once. Wedding planners tracking lead-up milestones, event organizers, sports fans following a season, travelers with multi-stop itineraries, small teams tracking product launches and campaigns, personal users combining trips + deadlines + celebrations on a single board.
