What you may give up

Production in-app design editor requires a separate commercial Polotno SDK license.

Operate your own infrastructure and register platform developer apps; approvals and analytics scopes required.
AI uses your own provider keys and provider billing.
X analytics availability depends on your X API plan.

Tier C: AGPL core; vendor claims ungated Cloud parity, but production design editing depends on licensed commercial Polotno software. Tier C for that workflow; scheduling itself remains open. License source
