Having switched from Bubble recently, I have been testing out a few hosts and the easiest so far to work with for me has been a nodeJS server on Digital Ocean
If you have more than one bubble site, your operational costs will likely be lower regardless of your choices when you switch to Wappler because the per-site costs are lower in my estimations so far
I recently bid a project that required the production plan on bubble and we are getting a lot faster server for less than half with digital ocean, and so much more control if we need it
Of course, the bubble plan included features that digital ocean does not - such as the bubble editor and some of the built-in easy to use features like the automatic SSL registration for HTTPS on your domain and the app caching
I have not found any surprise expenses so far; if anything the hosting is so much cheaper that if you have more than one bubble site it seems you’ll save a lot every month by transitioning to Wappler
Our clients have complained in past about the price jumps between available bubble plans; it is refreshing not to have to worry about trying to prepare a client to jump from $120 hosting to $500 hosting for one reason (happens to us on Bubble sometimes).
Because of the control and flexibility of digital ocean, we could have probably just gone from $120 to perhaps a $200 plan rather than jumping all the way to bubbles next much more expensive plan that is often about 3-4x the cost of the previous.
Given that these savings are per site & per month/year, it adds up. We have just re-bid a project on non-Bubble hosting and the monthly fees went down ~40% even with us taking into consideration needing more time on a new system. The client was thrilled because the monthly hosting fees were their biggest ongoing cost
I have been looking at a lot of project scopes and have only found a few (2 IIRC) out of ~110 active Bubble sites (109 tomorrow ) that may cost more on D.O. due to weird use patterns
These are sites with really unique scenarios where there might be an expense beyond standard hosting, database storage, backups, domain and certificates (such as a specific server-based search daemon, etc.)
Time will be the biggest expense as you learn, but I am finding it well worth it!
