ChatGPT SDK Unlocks New Developer Integration Paths
OpenAI Opens Submissions for Apps Using ChatGPT’s SDK, Unveiled at DevDay
The quiet hum of innovation at OpenAI’s DevDay in October has grown into a loud signal. Today, the company flings open the gates: developers can now submit apps built on ChatGPT’s SDK. That SDK, still in preview, is no mere plugin, it’s a bridge, engineered on the Model Context Protocol (MCP), an open standard for secure, tool-to-model handshakes.
Early pilots with Booking.com, Canva, and Spotify proved the concept. Now the roster swells: OpenTable, Apple Music, Target, and others have joined the fold. But access comes with a price, OpenAI promises a rigorous, safety-first review.
Every app must pass scrutiny on privacy and transparency before it touches a single user. The ecosystem is no longer a curated showroom; it’s an open market, and the rules are clear.
The move builds on OpenAI's Apps SDK, which was unveiled at DevDay in October. The SDK allows users to interact directly with apps inside ChatGPT and is currently available in preview. The Apps SDK is built on the Model Context Protocol (MCP), an open standard that enables models to connect securely to external tools and services.
OpenAI's pilot partners, including Booking.com, Canva, Coursera, Figma, Expedia, Spotify and Zillow, were among the first to launch app integrations. The ecosystem has since expanded to include apps such as OpenTable, Airtable, Apple Music, Replit, Target, Agentforce Sales and others. OpenAI said all ChatGPT apps are subject to a structured review process focused on safety, privacy and transparency before publication.
This is the moment OpenAI stops curating and starts scaling. By opening the floodgates to any developer willing to submit, they are betting that the ecosystem, not the company, will define what ChatGPT becomes. The review process is the only wall; safety, privacy, and transparency are not afterthoughts but the price of admission.
For users, it means an app store that grows faster than any single roadmap could predict. For developers, it is a direct line to millions of active chat sessions, provided they play by the rules. The SDK is no longer a promise.
It is a platform. Now the question is not who gets in, but what happens when everyone does.
