What it is

A JavaScript and TypeScript library that provides an unofficial API interface to interact with ChatGPT, allowing developers to integrate AI chat functionalities into their applications without official support.

This library offers an unofficial way to interact with ChatGPT, providing flexibility for developers who need a self-hosted solution but lack official API access.

When it fits — and when it doesn’t

A good fit for

  • JavaScript/TypeScript developers looking for an unofficial way to integrate ChatGPT into their projects.

  • Teams that need a self-hosted solution for AI chatbot development and testing.

Look elsewhere if

  • Projects requiring official support or guarantees from the API provider.

  • Developers who prefer using officially supported APIs with clear terms of service.

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

  1. 01

    Lack of official support and documentation

    Being an unofficial API, there is no guaranteed stability or updates from the original creators of ChatGPT.

  2. 02

    Potential legal risks associated with using an unofficial API

    Usage could violate terms of service and lead to account bans or other penalties.

  3. 03

    Limited functionality compared to official APIs

    The unofficial nature means it might not support all features available through an official API interface.

  4. 04

    Security concerns due to self-hosting requirements

    Self-hosting increases the responsibility for securing sensitive data and maintaining up-to-date infrastructure.

What it does well

  • Unofficial access to ChatGPT functionalities.

  • Support for both JavaScript and TypeScript.

  • Self-hosted, giving developers full control over their environment.
