I have used bubble for a product I switched over with Andrey's Sheet2Site. It is quite powerful and already a lot of plugins are available. You can practically build something for free until you want to add a Domain to it. I recommend watching the bubble tutorial videos on YouTube, there are a lot of them that cover quite some use cases.

Here's the channel:

There is a bit of a learning curve though and as it is super customizable, it might be an over-the-top solution if you build something very simple.
Cheers
