ChatGPT App for Your SaaS · $599 · 7 business days after access · Coming soon
Let ChatGPT users use your product without leaving the chat.
The upgrade to a Custom MCP Server. OpenAI's Apps SDK is built on MCP, so we build an MCP server over your API with 1–3 actions, add the app's in-chat interface, deploy it with authentication, and get it working in ChatGPT developer mode. Then we help you prepare the submission for OpenAI's review.
ChatGPT App for Your SaaS is a fixed-price service from ChikuOS, run by Siddharth Mishra, an independent developer in India. Put your SaaS inside ChatGPT with a ChatGPT app (Apps SDK) that has 1–3 actions. It is planned at $599 with a turnaround of 7 business days after access, but it isn't available to buy yet.
