Show HN: SendBetter – Dynamic image rendering API (20x cheaper)

I built SendBetter, an API for generating dynamic images.

The idea: define variables (text, images), design once in our editor, and programmatically render personalized visuals.

Why I made it:

* Existing tools are expensive ($49 for 1k images → $0.049 per image) * SendBetter starts at $0.002 per image * Better, modern editor * Free 1000 credits on sign up * One-time credit packs for non-frequent users.

Use cases: Personalized emails and WhatsApp, OG images, social media posts, certificates, marketing campaigns, etc.
