Hi @y26, welcome to ziggit. Web Dev in zig is still fairly young. Those that you mentioned are the main players in the space right now.
http.zig is going to give you more of a “raw” connection, but is a great building block. Zap and Jetzig are more of an Express, or Rocket stile framework: routing and stuff already included.
That being said, they look to be pretty fleshed out. There will probably be bugs, but you can get started with them. It is a great time to dive in and tinker around.
That’s just my personal opinion. I think it’s great because when I try things and there are bugs, I can help make the project better by contributing upstream. Because things are still being fleshed out, you can have a more active role then just consuming a well established piece of software. Since these are newer projects, they are a bit simpler, so you can read and understand the code a bit easier.
Now that’s not for everyone: a lot of people just want to use stable, boring software. If that is the case, then it is not great. Depends on what you are looking for. ¯\(ツ)/¯
