FAQ

Q: Which social platform API keys do I need? A: Each platform requires its own OAuth app credentials. Register apps on the Twitter Developer Portal, LinkedIn Developer, Facebook Developer, etc., and obtain Client ID and Secret.

Q: Do AI features require an OpenAI API key? A: Yes — AI content generation requires an OpenAI API key (or compatible API). Local models via Ollama are also supported. You can still use scheduling and publishing without an AI key.

Q: How many social accounts can I manage? A: The self-hosted version has no account limit. You can connect any number of social accounts — great for agencies and multi-brand management.
