Cardsmith for Coaches & Course Creators: Design social-card templates visually, render them from a GET

Design social-card templates visually, render them from a GET request. Your self-hosted Bannerbear.

The tool this job usually means renting is Bannerbear, at $49/mo — roughly $588 a year, every year. Cardsmith does the job for a one-time $99 — running on infrastructure you control.
