OpenAI opened ChatGPT as an app market. Your product now ships inside it

At DevDay in San Francisco on September 29, OpenAI pushed out more than twenty announcements. They were not a loose pile of launches; they all point the same way. ChatGPT is being turned from a chatbot into the place where software gets discovered and run. OpenAI · CNBC

The core piece is Plugin extensions. Developers can now attach sidebar entries and interactive panels directly inside ChatGPT and Codex, along with viewers for the file types a product supports. Altman put it plainly on stage: you can build an editor or a dashboard into ChatGPT, even a whole workspace. OpenAI handles distribution. OpenAI Developer Community

Agents shipped the same day. Dots, powered by GPT-6 Astra, each get their own cloud computer and connect to more than 4,000 apps. You message them from ChatGPT, Slack, or Teams. The agent API widened too: the Agents API now supports computer use, and a new Pro 500 tier costs $500 a month. The Decoder · Agentpedia

The layer to watch is distribution, not the app store itself

TechCrunch read the package as ChatGPT becoming the place where software is found and used. More than thirty partners are in the marketplace at launch, Adobe, Figma, HubSpot, and Salesforce among them. TechCrunch

What matters for indie builders is the gap: the money layer is not there yet. OpenAI announced no revenue share and no billing system. Discovery and distribution are in place, identity is in place, but nothing moves dollars. The app store is not collapsing so much as discovery and execution are folding into ChatGPT itself. Whether your product gets found inside that surface or only reached by a link from outside is the next fork in the road.

Two things are worth trying now. Read the Plugin extensions docs and pick one screen from your product that would fit inside ChatGPT. Then take a workflow you already run and move it onto the Agents API with computer use. Dots rolls out first to Pro and Business Premium, so your actual users are not there yet, but the API side is open today.
