How to Combine Ads With a Subscription in Gradio
This guide shows how to combine ads with a subscription in a Gradio app, the goal being to run ads on the free tier and a paid ad-free tier together. It builds on the Monetzly gRPC service (no Python SDK exists for this stack), so the approach is specific to how Gradio produces and streams responses.
Overview
Ads and subscriptions are not mutually exclusive for a Gradio app. A common setup runs Monetzly ads on the free tier and offers a paid, ad-free tier for power users — capturing revenue from casual and committed users alike.
Implementation is a branch on the response path: enable injection for free-tier sessions and skip it for paying users, based on your own Gradio app's user state.
Gradio apps are usually built for model demos, chat interfaces, and shareable AI prototypes, so combine ads with a subscription typically comes up while a user is mid-conversation, the moment where monetization has to be additive rather than disruptive.
How this works on Gradio
Gradio is Python. Drive the shipped tps_alter.proto gRPC service (or a Node sidecar) and yield injected tokens from a gr.ChatInterface generator fn for streaming output. Confirm the non-JS auth handshake before publishing.
Since Gradio is a Python stack with no official SDK, this task runs through the shipped tps_alter.proto gRPC service (or a Node sidecar); the auth handshake for a direct client is still TODO_VERIFY.
Steps
- Determine the user's tier from your Gradio app's auth/session state.
- Run ad injection for free-tier sessions.
- Skip injection (return the plain stream) for paying, ad-free users.
