presenton/presenton: Open-Source AI Presentation Generator API Hits 4.4K Stars — Direct Gamma and Beautiful.ai Alternative
GitHub·medium signal
Presenton is an open-source, self-hostable AI presentation generator with a public API, explicitly targeting Gamma, Beautiful.ai, and Decktopus as commercial competitors to displace. At 4,363 stars, it's gaining traction in the vibe-coded tool category where AI generates full slide decks from prompts. The API-first design makes it composable with agent workflows — a distinction from consumer-facing presentation tools.
