Showdown, rebuilt.

Same server. Same ladder. Same players. A client from this decade.

Format Team

In this prototype, “Find a battle” starts a playable demo match vs the computer in the new battle UI. On the real server this button sends /search over the same socket the Live tab uses.

Your demo record: 0–0

What’s different?

Calc built in. Every move button shows a damage range vs the active opponent — no Showdex tab-juggling.
Readable log. Turn-by-turn, grouped, with damage % — not a wall of pipe characters.
Teambuilder that feels like software. EV sliders, usage-style move picks, one-click import/export.
Mobile-first. Big tap targets, one-column battle view.
Nothing to migrate. Your account, rating and teams live on their server — this is just a front door.

Your password goes only to Showdown's own login server, relayed by our Cloudflare Worker — their server doesn't answer browser pages directly (no CORS headers). It is never stored, logged, or kept after login. Using an unregistered name? Leave the password blank and it's yours for the session.

Import / Export

Paste any standard Showdown team export — the slots above update. Export regenerates paste text from the slots (edits and EV sliders included).

Live spectate REAL — official server

This tab opens a real WebSocket (SockJS transport) to sim3.psim.us, joins the lobby as a guest, lists live battles and renders any battle you pick with the new UI’s log parser. Spectating needs no account. Playing on the ladder needs the challstr login flow — that’s the next build step, not faked here.
