Deploy and Host LandPPT AI Presentations on Railway

LandPPT is an open-source, LLM-powered presentation platform: turn a topic, outline or uploaded documents (PDF, Word, Markdown…) into a complete, professionally designed slide deck. It supports deep research with web search, AI-generated images, a rich template library, an AI editing assistant and export to PDF / HTML / PPTX.

About Hosting LandPPT

This template deploys:

Service	Purpose
landppt	Official `bradleylzh/landppt` image (FastAPI web app, port 8000). Persistent volume at `/app/data` for generated artifacts. Database migrations run automatically on startup
Postgres	Users, projects, slides and settings

The image refuses to run as root, so the start command fixes volume ownership and then drops to the app's non-root user (UID 10001). A random SECRET_KEY and admin password are generated for every deployment.

After deploy:

Open the generated domain and log in as admin with the password from the landppt service's LANDPPT_BOOTSTRAP_ADMIN_PASSWORD variable.
Change the password, then add your AI provider (OpenAI, Anthropic, Gemini, DeepSeek, Azure, Ollama or any OpenAI-compatible endpoint) in the AI settings.
Create a project from a topic or upload documents and generate your first deck.

Common Use Cases

Generate pitch decks, lecture slides and reports from a topic in minutes
Convert long documents and research into structured presentations
Deep-research mode with Tavily / SearXNG to build fact-based decks
A private, self-hosted alternative to Gamma-style AI presentation tools for your team

Dependencies for LandPPT Hosting

PostgreSQL (included)
An API key for at least one LLM provider (configured in the UI or via variables such as OPENAI_API_KEY)

Implementation Details

This template runs in LandPPT's single-node mode (inline task execution, in-memory cache, local artifact storage on the volume). Optional extras: TAVILY_API_KEY for deep research, image-provider keys (Pixabay, Unsplash, SiliconFlow, Pollinations), and the separate ghcr.io/sligter/landppt-pptx-renderer service for high-fidelity PPTX export. For multi-instance scaling, switch to TASK_EXECUTION_MODE=queue with Valkey/Redis and S3 storage as described in the project docs.
