How can I build an app like Instagram using Java? What languages are used for the front end and database?

Why do people use your application?

Find your target people and How will you attract them on your application.

So designs and functionality matter! You need below points for Design & functionality.

• It is easy to use.
• It has the simple but beautiful design.
• It has many little and nice features.

For this, create some key features in your mind and choose better interface in which you are expert.

I found some modules as provided by Instagram.

Easy registration and authorization : Users can use email or phone number. You can also use social logins which are available on their developer sites(Ex,Social Facebook signup-login API visit Facebook for Developers, Google API visit Google Developers)

Profiles Module : That’s obvious, Every one want to know each other on social media, and another reason is to Identify user from their description or profile photo.You can Keep it simple: Name, avatar, small description and general information or website link. Allow your users to edit, add and remove information in one click (We call it CRUD functionality).

Communication : Most important part of any development. This kinda apps , which shares photo and feelings, you can tell it “social network”. You should add something like Follow or Unfollow, so Users can communicate with each other. You can add submodules like Like, Comment, Share, Direct Message(For chat), Follow etc.

Image customization and filters : Main heart of Instagram. You can put some best and rare filters which can be appreciated by users. No need to put 150–200 filters :)

Posting: purpose of posting is for users, they can share picture(s) from their local directory. So upload module is needed to achieve this functionality. You can also add these as a submodules : post description, mentioning people and adding people on photo (tag in terms of Facebook), Hashtags (Optional), searching (Filter by post,hashtags), so they are necessary.

Push notifications : Its optional for starting level, but you can take permission from users to allow notification, If user allows, you can show blinking notification like Facebook.

I would say, Instagram was made with Python - Django, but if you want to create such an app, you can use any you would like to do!

You need to keep in mind that…

If you are going to make application like Instagram you should have to care about,

Hosting,

Data storage,

Load Balancing,

Monitoring servers

Bingo… You have some basic planning about how to create such applications.
