Anvil doesn't require you to install anything. It is a completely cloud based IDE and web-app development tool. You CAN choose to self-host apps, but it isn't required.

I made both https://agaar.mongol.ai and https://election.songolt.org on Anvil. They are both publicly available. Agaar is an analytics app that tracks air pollution and weather data for Mongolia’s capital city. The election app is an electoral district analysis of the recent parliamentary election in Mongolia.

To see other sites you can check out the Show and Tell section on the Anvil forum. https://anvil.works/forum/c/show-and-tell/6
