This self-hosted presentation tool does everything Canva does, and it costs nothing

Presenton is a free, self-hosted, AI-powered presentation tool that serves as an open-source alternative to Canva. It runs in Docker with a single command, supports local AI models via Ollama (no API key required), and can generate full slide decks from prompts. It offers customizable templates, lets you set slide count and language, and exports to PDF or PPTX. Generation speed can be slow with local models, but it's a capable no-cost replacement for those frustrated by Canva's increasing paywalls.
