Tag your Polar.sh checkout links by channel + source. SourcePolar aggregates your Order metadata into a per-channel attribution dashboard. No more guessing whether DEV.to, X, or YouTube made the sale.
You see "5 paid orders this month." You don't see which channel — your DEV.to article, your X build-in-public, your YouTube comparison, your LP — produced each of them. Without per-channel attribution, the next channel investment decision is guess-driven.
SourcePolar generates a unique checkout link per channel × source, with metadata baked in. When buyers complete purchase, the Order inherits your channel tag. The dashboard breaks down paid_orders + revenue + refund rate by channel. Day 30 KPI judgment becomes actionable per-channel, not just binary.
All plans buy-once friendly. No long-term contract. Cancel any time. Polar.sh billing handles tax/VAT compliance.
