Switch Steam accounts in one click, and launch every game with the right account, monitor, resolution and sound.
SwapDeck solves a niche-but-real pain for multi-account Steam players: switching accounts usually means retyping passwords and Steam Guard codes. Here, one click does it — and pressing "Play" completes the whole ritual automatically: switch account, set the primary monitor, resolution and sound device, launch companion apps like SimHub, then restore everything on exit. Sim-racing setups with ultrawide monitors and wheel software are first-class citizens.
Author byteminite is blunt in the README's "How it's made" section: "SwapDeck is vibe coded: it was designed, directed and tested by me, and the code was written by Claude, using Claude Code running in Munder Difflin, a free, open source multi-agent harness." Ten days from zero to a complete desktop app with auto-updates, a tray panel, controller support and a playable browser demo (the site ships with made-up accounts so you can click through the real interface). Local-first: no accounts, no telemetry, data stays on your machine. Released 2026-09-29, pushed daily through 2026-10-08.
