Dev builds two free Polymarket dashboards with Claude Dashboards + Supabase
UnhappyTap9123 · reddit · 2026-11-10
A developer built two free Polymarket learning tools using Claude Dashboards (under Artifacts → Data) plus a free Supabase project: a market board (movers, order-book depth, rules) and a virtual-betting lab that fills simulated bets against live order books with fees, auto-settles, and tracks Brier scores and calibration with a loss-review screen. Workflow: have Claude write blueprint docs first, then one feature per prompt for Supabase (cache tables, pgcron, edge functions reading free Polymarket APIs) and the UI. Claude also traced a bug where a 60-item limit dropped unsettled bets. Honest limitations and reusable setup steps are included.
