The catalog
Backend and payments: Supabase, Stripe, RevenueCat. Code and builds: GitHub, Expo. Design: Figma. Models: OpenAI, Anthropic, Google AI, Mistral, Groq, ElevenLabs, Replicate, Perplexity.
Store accounts are deliberately not in this list. You publish to the App Store and Google Play from your own developer accounts, so Buildr never holds those credentials.
How connections are stored
Keys are encrypted at rest and only ever read server-side. Nothing is exposed to the browser or written into exported code. Removing a connection revokes its use immediately.
