Show HN: ChatAPI – PWA to Use ChatGPT by API (github.com)

I've built this PWA to use ChatGPT by API.

My main motivation was to use the API since it is much cheaper than the premium plan and I only pay for usage. The main inspiration was ChatGPT-web by Niek [1], but I was lacking time to dig into the code base to make changes. Hence I went for a lightweight approach with Alpine.js and Open Props. There is no build step, the dependencies are fetched via CDN.

In general it was much fun to work with Alpine.js - being a parent means having very little time. So it was great to not have to invest 20h into learning a new framework. My main ask was something that gives me data binding and does not require a build step. Alpine.js was the perfect fit!

A hacky bit I'm proud of is the dynamic loading of languages for syntax highlighting with highlight.js :)

Feel free to fork, adapt and host for yourself!

I use https://www.chatbotui.com/ all the time - not exactly the same approach you've taken, but is very useful.

For something a little heavier but much more robust in terms of features/functionality I've been enjoying FastChat: https://github.com/lm-sys/FastChat

It allows you to plug in different backends so that you can use OpenAI compatible clients with various LLM's, selfhosted or otherwise.

Similar concept but for the command line, with some more features: https://github.com/marcolardera/chatgpt-cli

I built a super-simple, 100% client-side chatgpt client because I wanted more control over what was sent to the API (system prompt, temperature, context window size etc): https://github.com/benrhughes/chat
