Cardsmith for Agencies: 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.

Agencies pay per-seat and per-client fees that scale with their success. Self-hosted, pay-once tools replace per-seat pricing with a flat cost that margins actually survive.

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.
