Heroku

Pros: You can say Heroku is the easiest cloud platform to learn and master. Also it is very much easy to implement. It is so simple that if you even have some basic knowledge of Git and Github you can easily master this technology. You can log the errors. And you can deploy your different project in this.

Cons: There is no con in using this product. This works fine for me.

Overall: Overall a great tool to host your web app with high security at very reasonable cost. Easy to implement and lot of tutorials and documentation which make it much more easy to use.

Pros: You cannot find any other better platform to deploy your web app. Also, scaling your app is very easy with this. You get the feature to checks your logs and also bash terminal to manage your files. Also, many backend and frontend languages are supported in this.

Cons: I have been using this for all my web development projects and I don't find any con in using this platform.

Overall: Overall a great experience. You can create up to 5 apps for free in this. And also, managing and maintaining apps with this is pretty much easy. And also, it is very easy to use just 3 git commands to host your app.

Pros: Online and offline log support
Terminal Support
Easy to use - Same as git
Powerful and reliable
Secure

Cons: You need to know the basic of Heroku to start and what is Procfile and other stuff.

Overall: I have hosted all my dynamic sites on Heroku. On free tier you can host up to 5 projects and the log and the terminal support on the web helps more to find the issues and fix them.

Pros: I have recently used this for generating API this was my first time but I didn't face any problems, very easy to use.

Cons: You need little bit knowledge about API and Heroku.

Overall: Best for generating API.
Make your backend more interesting with the help of Heroku.
Easy to use for API.

Pros: Whether you're at a hackathon or just quickly prototyping a new app for your company, chances are high you want real users to be able to try your app. You could just host it on a localhost, but that means you can't direct people to a proper URL. Heroku allows you to do that.

Cons: I first heard of Heroku back in 2015 and a few years later I swear I heard it was shutting down? But apparently it's still usable, so I'm not sure what exactly was going on. Company communications can be better, in this regard.

Overall: One of my favorite go-tos when creating an app at a hackathon or making a quick demo prototype. Saves the trouble of registering a domain name and all.

Pros: Highly customizable.
Automatic Scaling.
Easy deployment.
Secure & stable.
Great documentation.
Free tier available.

Cons: Has a decent learning curve.
Layout can be improved to make navigation better.
More expensive than alternatives for heavy usage.

Overall: Heroku makes hosting web apps easier. With a ton of customization options & fast deployment, it is an ideal choice if you want to quickly want to make your app live.
