OpenAI API Alternative: app.nz
The OpenAI API is the default starting point for teams using frontier models and the OpenAI SDK. app.nz provides agents, hosting, deploys, model routing, and GPU infrastructure.
OpenAI API Alternative: app.nz

Where OpenAI API is strong
- Frontier models and a widely used SDK shape.
- Large ecosystem of examples and client libraries.
- Suits OpenAI-only access.
Where app.nz is different
app.nz covers:
- cloud coding agents that work on repos and return durable diffs
- static sites, server deploys, private container builds, domains, logs, queues, and secrets
- one OpenAI-compatible gateway for text, image, video, audio, embeddings, search, and 3D
- scale-to-zero GPU hosting for Cog and Comfy workloads
- one credit balance and API surface across the product
app.nz keeps the OpenAI-compatible shape, routes across providers, and adds app deploys, coding agents, and GPU endpoints.
Choose OpenAI API when
Choose the OpenAI API directly for vendor access without cross-provider routing or app hosting.
Choose app.nz when
app.nz runs the whole loop on one account: an agent edits code, the build deploys, model calls go through the gateway, and GPU endpoints run on demand.
Migration path
Switch the base URL and API key, then use app.nz model ids or auto routes.
Bottom line
app.nz hosts the app, routes the models, and runs the GPU or worker infrastructure behind them.
