1) Custom Backend
Building a custom backend as a Parse alternative can be an overwhelming errand, yet in the event that you have a touch of involvement with a server-side programming language and know a thing or two about servers, this abstains from having a reliance on an organization that might close down.
What's more, since you have full control, you can manufacture convenient some custom components. For instance, on the off chance that you needed to do some extravagant picture preparing or optical character acknowledgment you have free rule to do whatever you require.
A custom backend takes a great deal of time to assemble, and thereafter requires customary upkeep – and for some little applications, this expense may not be justified regardless of the advantage. You likewise need to take the standard security safeguards like getting a SSL Certificate, ensuring database access, and so on.
As opposed to keeping up your own foundation, I'd prescribe utilizing a service like Heroku or Microsoft Azure to make it less demanding. Composing some of your own code can present server-side bugs, which notwithstanding customer side bugs, can be a considerable measure to handle.
To put it plainly, revealing a custom backend is a compensating knowledge and an extraordinary learning opportunity that gives you huge amounts of force and adaptability, however consequently costs a huge amount of work.
In iOS 8, Apple presented CloudKit – another new data storage service for applications taking into account iCloud. It gives a minimal effort choice to store and share information utilizing clients' iCloud accounts as a back-end stockpiling service.
CloudKit is extraordinary as a Parse alternative if information diligence is the top need. The officially liberal use limits increment as your application gets more clients, which implies that CloudKit will probably be free for generally applications.
The inherent memberships/notices can be helpful for social or other substance sharing applications. Your application can subscribe to changes on specific items, and CloudKit will send the application a notice when those records are changed.
3) AWS Mobile Hub (DynamoDB, Lambda, API Gateway, Cognito)
Mobile Hub incorporates numerous AWS services that handle client related errands like validation, information stockpiling, backend rationale, push warnings, and more in one advantageous dashboard. At an abnormal state, API Gateway uncovered (through URLs) code that is composed in Lambda. Lambda capacities can then utilize numerous different services, including DynamoDB (a database) and Cognito (utilized for validation).
AWS's liberal cutoff points and sensible evaluating imply that for a little application you might not need to pay by any stretch of the imagination, and as your application develops you won't need to pay significantly more. Mobile Hub likewise has a convenient component that can create custom customer SDKs for iOS or Android taking into account what you have set up.
Mobile Hub and its parts are exceptionally adaptable and can deal with any measure of clients you can toss at it. AWS is becoming quickly and Amazon keeps on putting resources into it, so I can't envision it will vanish at any point in the near future.
Thus, the above are the top 3 Parse alternatives to choose from.
