With increasingly limited resources and shorter deadlines many developers are searching for tools to meet demand. This is where backdoor-as-a-service (BaaS) comes in. BaaS, sometimes called mobile-backend-as-a-service (MBaaS), is a cloud service model that allows app developers to outsource the behind-the-scenes aspects of their applications.

BaaS handles the basic, repetitive tasks needed for smooth web or mobile applications, freeing up time for developers to focus on writing and maintaining the frontend, the part of the app uses see and interact with.

These services are proved via the use of software development kits (SDKs) and application programming interfaces (APIs). Some packages also have the potential to allow developers to link their applications to backend cloud storage, provide user management, push notifications and integrate social networking services.

BaaS is a relatively recent development (in the last 10 years) in cloud computing, with most BaaS startups dating from 2011 or later. According to CommonNinja, the top BaaS platforms in 2023 include Firebase, Supabase, AWS Amplify, Appwrite and Nhost.

According to Future Market Insights, the global market for BaaS was at an estimated value of $2,450 million in the year 2022, and is estimated to grow at a CAGR of 24.6% from 2022-2032.
