Shipped Countspace today, a countdown-boards app I've been chipping at nights/weekends. Basic idea: stack multiple countdowns on one board and share the link, instead of the usual one-countdown-per-URL sites.

Posted on a couple subs this morning and got one really good comment from a top commenter on r/SideProject that made me realize my landing page explains the concept in words when it should just show a personal example board upfront ("summer trip + wedding + festival" style). That kind of hurt but useful.

Anyone else launching this week? Would love to swap notes on what's actually working (or not). Also open to a quick look if you have a sec, mostly want to know if the "boards of countdowns" thing clicks or feels weird.

Solo built, Next.js + Supabase. First day of real traffic. It's a lot.

Just launched Countspace, a small side project — the pitch is "one board for all the countdowns you care about" instead of the usual one-countdown-per-URL apps.

Stack + notes on choices:

- Next.js 15 App Router. Public board + explore pages are server components with force-dynamic; realtime countdown ticks are the only client boundary.

- Supabase for Postgres + RLS + Realtime. RLS policies are the entire authorization layer — no separate API auth code.

- OG images generated on demand via next/og, cached by Vercel per slug.

- Event JSON-LD injected server-side so Google can surface upcoming events as rich results.

- Separate embed.countspace.app subdomain handled by middleware — main app ships strict CSP with frame-ancestors 'none', embed subdomain opens it up so third-party sites can iframe boards.

Free tier is 3 countdowns. Feedback welcome — especially on the App Router patterns.
