Presenton

Open source AI presentation generator, self-hosted alternative to Gamma

Alternative to: gamma, canva, beautiful.ai, decktopus

Presenton generates fully editable presentations from prompts, documents, or your own PowerPoint templates using AI, with drag-and-drop editing and export to PPTX or PDF. It can run entirely on your own infrastructure with local models through Ollama, or connect to OpenAI, Gemini, Claude, or Azure OpenAI, giving you a self-hosted alternative to cloud AI presentation tools.

Presenton Docker Compose example

Self-host Presenton on your own server, homelab, or VPS starting from this Docker Compose example. It runs Presenton in Docker containers using the official ghcr.io/presenton/presenton:latest image, with persistent volumes and automatic restarts preconfigured. Review the environment variables and adjust them to your setup, save the file as compose.yml (or docker-compose.yml), and start the stack with docker compose up -d.
