As answered by people managing Learn Git Branching and Countspace.
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.
Countspace's answer:
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.
