HostedGPT

HostedGPT is a free, open-source chat interface in the style of ChatGPT. You can run it on any server or even your own computer. It's a Ruby on Rails app. Just bring your own OpenAI API key. All the core functionality of ChatGPT is already working (e.g. GPT-3.5 and GPT-4, starting new conversations, streaming responses, asking about attached images, etc). The main thing missing is the mobile app but that's coming soon and it already works well as a mobile web app.

Plus, this app has extra features. You can use Anthropic's Claude 3 in the same interface as GPT-4. You can also switch assistants in the middle of a conversation.

This project is actively looking for contributors to help make it great. The goal is for every feature that exists in ChatGPT to exist in this app along with many improvements.

Some favorite features of HostedGPT

Enjoy chat history, but without your private conversations being used for training!

Did you know that all your private, personal past conversations in the left sidebar are allowed to be used for OpenAI training? Disclosed in this OpenAI article. HostedGPT excludes your history from OpenAI training.
Don't commit yourself to $20 per month when you may not use ChatGPT a lot. You only pay as much as you use!
You will never hit the 'You've reached the current usage cap for GPT-4'. You pay per mesage based on the API rates so you can keep using it as much as you want.
Use Claude 3 and soon Gemini in the same app as GPT-4. You won't have your conversation history split across three apps and have different interfaces for each one.

Set Up Live App

You can deploy a full version of HostedGPT to the hosting service, Render, for free. This free app works for 90 days and then the database will stop working. You will need to upgrade to a paid version of the database which is $7 / month. Alternatively, you can also run it off your local computer. Jump down to the Developer Instructions if you want to run it locally.

Click Fork > Create New Fork at the top of this repository
Create an account on Render.com and login. If you are new to Render, you may be prompted to add a credit card to your account. However, you will be on their free plan by default unless you choose to upgrade.
View your newly created fork within github.com and click the button below:

In Blueprint Name, type anything such as "hostedgpt-"
Click Apply
Wait for the hostedgpt database and web service to be deployed. The first deploy takes a good 5 minutes so be patient. After they are all deployed, click Dashboard at the top of the Render screen. Or if an error occurs, skip to Troubleshooting Render below.
You should see two "Service Names" called "hostedgpt-..." (the name you picked), click the one that is of type Web Service
On the details screen, click the URL that looks something like hostedgpt-XXX.onrender.com

NOTE: After 15 minutes of not using the app your Render server will pause. Next time you visit the first request will auto-resume the server, but this resume is slow. If this annoys you, upgrade Render for $7 per month:

Go to your Render Dashboard
Click "HostedGPT" or whatever you named your Web Service
Click "Upgrade" and select $7 per month

Troubleshooting Render

If you encountered an error while waiting for the services to be deployed on Render, click Dashboard at the top of the Render screen and click the Service that failed.
It should take you to the Events section and the top event should explain the error. It will probably contain a link to click to the deploy logs
Scroll back up through the logs and find any instances of errors. Open a new Issue for us and share details.
When you are ready to try Render again, it's best to do the following:
First, ensure your repo is caught up. Open your fork in github, click the Sync Fork button so that any bug fixes are pulled in.
Second, in Render navigate to the Dashboard, Bluebrint, and Env Groups and delete any details associated with hostedgpt
Now you can go back to your repo and click Deploy to Render

Contribute as a Developer

We welcome contributors! After you get your developoment environment setup, review the list of Issues. We organize the issues into Milestones and are currently working on v0.8. View 0.8 Milestone. Look for any issues tagged with Good first issue and add a comment so we know you're working on it.

Setting up Development

The easiest way to get up and running is to use the provided docker compose workflow. The only things you need installed on your computer are Docker and Git.

Make sure you have Docker Desktop installed and running.
Clone your fork git clone [repository url]
cd into your clone.
Run docker compose up to start the app.
Open http://localhost:3000 and register as a new user.
Run tests: docker compose run base rails test
Open the rails console: docker compose run base rails console
Run a psql console: docker compose run base psql

Alternatively, you can set up your development environment locally:

HostedGPT requires these services to be running:

cd into your local repository clone
asdf install to install the correct ruby version
bundle install to install ruby gems
bin/rails db:setup < Note: This will load the sample fixture data into your database
bin/dev < Starts up all the services
Open http://localhost:3000 and register as a new user.
