Short answerChoose a plugin if your users stay in ChatGPT and you may need tools through MCP. Choose a hosted bot page if you need a public link without ChatGPT and your bot only needs instructions and files.
| OpenAI plugin | Hosted bot page | |
|---|---|---|
| Who can use it | People with ChatGPT who install it | Anyone with the link |
| Actions | Rebuild with apps or an MCP server | Not supported on GPT Migrator hosting |
| Model costs | Within the ChatGPT plan, per OpenAI's plan terms | You pay your API provider |
| Setup effort | Migrate button plus testing | Upload files, add your key |
| Control | OpenAI's product rules | Yours, within the host's limits |
OpenAI's migration guide notes that recipients install plugins and that you need the Share plugins permission: sharing. For hosting see how it works. You can do both: migrate to a plugin for team use and host a public version.
Decision flow: alternatives.
Need your GPT running again without ChatGPT?
GPT Migrator can host your instructions and files as a standalone chat page for $47 per month. You bring your own OpenAI or Anthropic API key. It answers from your instructions and files and does not run GPT Actions.
