HostedGPT
HostedGPT is a free, open-source alternative to ChatGPT also supporting other providers (Anthropic, Google, Llama, Groq, etc.). It's a Ruby on Rails app so you can run it on any server or even your own computer. Just bring your own API keys.
You can have multiple users so it is great for a family or group.
You can also switch providers and models in the middle of a conversation, so it is great for comparing different models!
And you can attach your Google email, tasks, and calendar accounts and manipulate them in your conversation. Your assistant can also do web searches itself if you get a free Brave Search API key, and use the tools of any remote MCP server you add as a connector.
This project is led by an experienced rails developer, but we're actively looking for contributors to help!

Deploy the app on Render
For the easiest way to get started, 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.
UPDATE: The free service appears to not have enough memory HostedGPT, so you will probably need to upgrade to a paid service in Render, which is currently $7 / month. Alternatively, you can 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 (be sure you're viewing your fork of this repo before clicking):
-
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 with the free service your Render server will pause. Next time you visit the first request will auto-resume the server, but this resume is slow. You probably need to upgrade to $7 per month anyway (see above), which won't have the pause:
- To upgrade, go to your Render Dashboard
- Click "HostedGPT" or whatever you named your Web Service
- Click "Upgrade" and select $7 per month
