AgentKart vs GPT Store

AgentKart is a free, open-source web marketplace for AI agents. It is designed for discovering, sharing, and collaborating on agents through a curated marketplace. Visitors can browse the listed agents, while people with agents can submit them to reach a global audience. Publishing access is open, so contributions are part of the service’s stated purpose rather than a restricted workflow. AgentKart focuses specifically on AI agents instead of a wider software catalogue. The site presents community participation alongside discovery and sharing, giving users a place to explore available agents and contribute their own. AgentKart says its source code is available on GitHub, although the linked repository returned a 404 when opened. The listed platform is web, and no paid plan is specified.

GPT Store lets signed-in ChatGPT users browse and use GPTs, versions of ChatGPT configured for specific purposes. The Store features partner and community GPTs in categories including writing, research, programming, education, and lifestyle; users can also open GPTs through direct links or workspace settings. A GPT can include instructions, conversation starters, uploaded reference files, and capabilities such as web search or image generation. It can connect to outside services through apps or external API actions, but cannot use both in the same GPT. GPTs are designed to work in ChatGPT and cannot be embedded in an external website or application. Each conversation starts without saved memory, custom instructions, or earlier conversations. Builders cannot view individual conversations. If a GPT uses an app or external API, relevant input may go to that service, whose data handling OpenAI does not audit or control. Personal Free, Go, Plus, and Pro accounts cannot publish new GPTs; workspace publishing depends on settings and permissions. Free access is listed, with limits on messages, uploads, image creation, and voice chats. OpenAI says retirement is planned for affected Enterprise workspaces on December 11, 2026.
