Apps SDK Preview: Plan, Build, and Deploy ChatGPT Apps

OpenAI’s Apps SDK page outlines how to design, build, and deploy ChatGPT-native apps. It stresses quality via design and developer guidelines and provides a clear path: research use cases, set up an MCP server, and deploy. Supporting guides help with metadata optimization, security and privacy, and troubleshooting, with the SDK currently in preview.
Key Points
- Apps SDK is available in preview now for building and testing; app submissions will open later this year.
- Quality is central: follow App design guidelines and App developer guidelines to align with ChatGPT-native UX, safety, and policy standards.
- The recommended workflow is Plan (research use cases), Build (set up an MCP server), and Deploy (ship your app).
- Guides cover Optimize Metadata, Security & Privacy, and Troubleshooting to improve discovery, safeguard users, and resolve issues.
- Resources and references are provided to support end-to-end development and integration with ChatGPT.
Sentiment
Overall, the sentiment is **mixed to cautiously skeptical**. While there is recognition of the technical advancements and potential for a large user base, a dominant theme is developer fatigue and significant doubt regarding the user experience efficacy of chat-based interfaces. Many commenters express cynicism about OpenAI's strategic motivations, comparing the SDK to past 'app store' failures and viewing it as a move to build a 'walled garden' ecosystem.
In Agreement
- The rapid pace of new tools and SDKs, while challenging, fosters a thriving ecosystem of competition and innovation.
- Modern LLMs offer genuine language comprehension, making current chatbot initiatives fundamentally more capable than older, regex-based systems, and this comprehension is often underutilized.
- The Model Context Protocol (MCP) is seen as a positive directional step, addressing protocol gaps and enabling the return of UI elements to the client, which expands possibilities for LLM-integrated applications.
- The potential to reach a large user base (e.g., 700M ChatGPT users) presents a significant opportunity for developers, reminiscent of the early success of the iPhone App Store.
- The concept of micro-scoped LLM instances coordinating tasks via workflows is effective for automation.
- Similar 'super app' functionalities (like Tencent's WeChat) demonstrate a proven model for integrated platforms.
Opposed
- Developers are experiencing significant fatigue due to the constant churn of new models, tools, and SDKs, feeling overwhelmed by the need to continuously learn new paradigms.
- Conversational user interfaces are criticized as opaque, lacking 'affordances' for discoverability, and being brittle in real-world use, leading to user confusion and a preference for visual elements over language-heavy interactions.
- This initiative is seen as primarily reinforcing OpenAI's 'walled garden' and moat, with developers effectively building OpenAI's platform and potentially cannibalizing their own opportunities, similar to past platform plays.
- Many view this as a repeat of OpenAI's previous 'app store' attempts (e.g., GPTs) and other companies' chatbot platform flops, predicting a similar lack of widespread success.
- Skepticism exists regarding the monetization strategy for developers (revenue sharing, potential for hidden ads, preferential discovery), and doubts are raised about the economic viability for small independent developers.
- There is disappointment that OpenAI, having promised AGI, is instead delivering SDKs and 'TikTok clones,' seen as a distraction from their core mission.
- Current MCP-UI implementations are considered too slow for practical use, and there's a desire for entirely generative UI solutions over hard-coded widget schemas to overcome brittleness.
- A platform needs a strong user moat or unfair advantage beyond just a 'better quality model' to succeed long-term.
