Products that do what Simple OpenAI Playground Clone does
Hey HN! I love the OpenAI Playground UI but I don't love the Auth0 implementation causing me to waste precious minutes entering 2FA codes... so I spent a week cloning the basic features of the OpenAI Playground UI, all in a single HTML file. You can try it on github pages[0] or run it locally in your browser. Just paste your API key and hit start to begin using it. You can also add your key to the URI fragment[1] and bookmark it to start immediately. [0] https://minwidth0px.github.io/gpt-playground [1] like https://minwidth0px.github.io/gpt-playground#API_KEY

Hi HN, We're a small team building AI tutors out of India, and as you might guess, this means we spend a ton of time writing, testing, and refining prompts for LLMs. When we started out, we were using the OpenAI playground but things became tedious when we wanted to compare responses from different models. We tried a bunch of other playgrounds but found them lacking in some features so we built our own.

I made a ChatGPT client that is contained in 1 HTML file. Would love to know what you guys think. The idea is to have something very simple to use that people can just download and use. If they want, tweak as per their liking. (You will need an OpenAI API to use it). - It doesn't call or use any 3rd party services (except jQuery and Bootstrap loaded from a CDN). Use your own API key, call the OpenAI API directly in its normal functioning ( there is a chatbot feature to pull top HN headlines which calls the HN API ). - Its just an HTML file, so you can run it from anywhere. Repo:…

Hi guys, For my startup at www.mithrin.ai which is about create AI Chatbot Agents for websites, I wanted to create some free tools to attract traffic to the site and decided to create specialized chatbots powered by LLMs, similar to OpenAI's Custom GPTs. I realized that by using gpt-4o-mini, I could create quite powerful alternatives to GPTs that are free to the public for a very small cost (given how cheap the model api cost is). I've employed some throttling to prevent abuse and to avoid being charged too much. Then I integrated this with my main service and allowed users to use the…

Code base is here https://github.com/clairefro/aribotle Screenshots and learnings in tweet https://twitter.com/clairefroe/status/1684692302843838464?t=... I experimented with a "Bring your own API Key" approach that I think is sufficiently secure. I'll Venmo $50 to whoever can hack my OpenAI API key

We have been using GPT to write code since playground days. This UI avoids logins, gpt-4 throttling and is also cheaper to use than ChatGPT Premium. We also have various features to minimize costs and speed up iteration. Furthermore html & mermaid previews are a taste of the kind of features help-yourself opensource model enables vs official UI. For backstory see our blog posts: https://blog.humphd.org/chatcraft-org/ https://taras.glek.net/post/chatcraft.org-opensourcechatgpt-...

Hello Folks, I am an indie developer, For the last 5 months I was freelancing by building GPT-powered chatbots. One of the challenges I faced was not having visibility into my OpenAI costs. This is why I have built a dashboard to get a complete breakdown of my OpenAI API usage through network calls from OpenAI. Please give it a try & help with feedback on how I can further improve the product,which can really add value and save some money. Note: 1)I found this API through the network logs of the billing screen. 2)The tool stores the OpenAI Key locally on the browser.

Hello HN - like a lot of programmers, I am really excited by everything going on with ChatGPT/DALL-E. I am a game developer by trade, and I think there is a lot of potential to change workflows for game development. I was very inspired by Keijiro Takahashi's prototypes for asset generation using OpenAI within Unity, so I tried to make a more generic means of generating text and image assets within the Unity Editor using OpenAI's APIs. I've been surprised by the success so far - it definitely has it's limits, but I think we have just begun to scratch the surface of the potential here.

Type /ai + your prompt in any textbox and the ChatGPT will do the job I've made this project so I could learn how to create Chrome extensions. I know there are already a lot of alternatives for it, but this was a learning project and I would love some feedback on the code. ( I was unable to make it work on sites that use the React Lexical editor, i.e Reddit, Facebook, etc :( )

I'm building an AI platform, FlowChai and found a neat use case for it today that I thought would be useful to HN readers. I use GPT4 heavily for writing / editing code, but a major downside is that it doesn't know about new projects. I made the connection today that I could upload the zip file of a Github repo to FlowChai and then write prompts just like with ChatGPT with code questions. While the original intent for this platform is more around natural language, it's neat how this works so well. It's powered underneath by pgvector and OpenAI embeddings.

Hi hn, Its been a while since my kid has been dreaming to make videogames, as you know, the entry bar is high, too many technical details are involved. A few months ago, we started making games, we have tried many different ways, from dragging blocks to write code with a high-level library to make it simple, it is still too much work. Getting into the AI boat, I decided to give it a try for making games, turns out that it works super nicely, still, you still have many technical concepts involved, what language should the game be written in? where do you store the file/assets? how do you…

Hey all, Just showcasing something I've been hacking on with a friend we decided to open source. Proxy GPT is a GPT backend powered by OpenAI. It includes a team based chat api, user signup, login, context caching and much more. It's an abstraction layer on top of OpenAI's chat API that makes it slightly easier to programmatically build chat apps that might require custom user signup/auth, separate teams and chats, etc. Let me know what you think. https://github.com/asim/proxy-gpt

I was looking for a tool to create interactive demos / walkthroughs for web based software. I was amazed that many companies charge well over $1000 per month for something pretty basic. I made this which so far works well for me. You can point it at a site and either let AI (byo OpenAI or Anthropic keys) record and polish the whole thing or do it manually yourself (or a mixture of both). Here is an example interactive demo: https://runnit.io/demos/i-want-you-to-create-a-demo-of-from-... Disclaimer: This is a tool which works for me and may work for you, it's not…

Text → GPT → p5 | An app that turns your text prompt into p5js code (computer graphics) using OpenAI's GPT and displays it. Under the hood: Nextjs, React, CodeMirror, p5js I got into programming through arduino and processing. I've always thought about how to lower the barriers for people to start programming. With GPT, we can now turn plain text into code, allowing people to start coding without knowing code. OpenAI APIs don't come cheap! If you like the project, consider sponsoring access for others here: https://www.buymeacoffee.com/mattelim Cheers!

Hi folks, I’m one of the maintainers and co-founder of the Go OSS project Permify (https://github.com/Permify/permify), an open-source authorization infrastructure inspired by Google Zanzibar. I would like to share a post where we aimed to provide a brief overview of how we integrated WASM with Golang to provide a richer user experience in our open-source playground. You can use the playground to create and test any authorization logic in a browser. The playground has three main sections: Schema: to model your authorization logic through our domanin specific language we…

Hey HN! Quick TL; DR: I set up scrapers for the websites of ~20k tech companies, fed the results through GPT, spent some sleepless nights building a web app, and voilá. I started this after getting fed up with how slow LinkedIn felt. I finally got it working and easy to use, so I wanted to share it with you guys. The job list is free. But I’m currently paying a lot of money to OpenAI for all the data I’m passing through GPT, so I may end up eventually charging for some advanced features, or putting ads on it or something. Please let me know what you think! I’m actively developing this so I’m…

800M people use ChatGPT and Claude weekly. Right now they get text responses. Soon they'll get real interfaces: product cards, blog posts, booking flows, payment screens rendered directly in the conversation. We built an open-source component library for this. Install any block with one command and customize it to your brand. If you're building MCP servers or experimenting with AI-native apps, this might save you time. Are you building apps for AI assistants? Would love to hear what's missing in your workflow.

I’ve spent the last 2.5 months building a product that runs LLM-powered code reviews on my pull requests — and I just launched it. The tool is built specifically for solo developers. You install it on your repo, trigger a scan by creating a pull request, and it leaves structured review comments using OpenAI under the hood. Funnily enough, I used the dev version of this app to review its own pull requests while building it. It helped me spot bugs, simplify structure, and keep quality high — all with minimal need for another human in the loop. Things I want to try out in the next months : -…
