Presenton

Open Source REST API Self-Hostable

Best for: Developers and teams who want Gamma-style AI presentation generation without vendor lock-in — self-host it, call the REST API from Claude or any script, and own your data

Not ideal for: Non-technical users who just want a polished deck fast — Gamma has a better out-of-the-box UI; Presenton's strength is programmability and self-hosting

📤

PPTX Compatibility

3.2

Programmability is Presenton's advantage over Gamma. Setup ease reflects the Docker/server requirement — not a one-click install. Visual quality is good but behind Gamma's polished templates.

# Self-host with Docker
git clone https://github.com/presenton/presenton
