DIY ChatGPT apps without the plumbing

What it does

OpenGpt is an open-source web platform that lets anyone spin up a ChatGPT-powered “App” — essentially a packaged prompt with a UI — and let others run it. Think of it as a tiny app store where the inventory is user-generated prompt wrappers. You can also bring your own OpenAI API key to bypass rate limits.

The interesting bit

The project leans hard into user-generated content: over 800 user-created apps appeared in three days after launch. That velocity suggests the barrier to entry — prompt + config, no code — hit a sweet spot for the March 2023 ChatGPT gold rush.

Key highlights

• Users can run existing apps or create new ones from the web UI
• BYO API key support for removing rate limits
• i18n support and homepage curation to hide broken apps
• Live at open-gpt.app
• Built in TypeScript; open source under what appears to be a standard OSS license

Caveats

• README is sparse on architecture, deployment, or contribution docs
• “Planned Features” checklist is frozen in March 2023; unclear what has shipped since
• The “App” concept is thin — these are prompt templates, not standalone applications

Verdict

Worth a look if you need a quick internal prompt-sharing platform or want to study a minimal viable GPT wrapper. Skip it if you need deep customization, multi-model support, or evidence of active maintenance beyond the initial launch sprint.
