A $9 English digital product for US indie hackers: thirty daily build-in-public prompt cards, a tracking table, missed-day filler, and hard rules against fake user or revenue counts. Open PRODUCT.md on the landing for the full calendar. Pay once with USDC on Base. No SaaS clone, no ad-spend advice, no invented forecasts. Built for makers who want an honest public build log without padding metrics.
Indie Offer Lab ships original English digital packs for Marc Lou-style indie hackers. We sell small, fulfillable worksheets and calendars on GitHub Pages with Base USDC checkout. This calendar exists because fake build logs waste trust; each day has a concrete job and a skip rule beats inventing numbers.
