Backendless vs Supabase

• Backendless provides a much higher storage ceiling, offering up to 100 GB in its top tier, whereas Supabase caps its integrated storage at 8 GB before hitting enterprise-level custom contracts.
• Supabase maintains a lower storage overage penalty at $0.13/GB compared to the $0.15/GB charged by Backendless.
• Data egress limits favor Backendless, which includes up to 500 GB of bandwidth, while Supabase restricts standard plans to 250 GB and charges $0.09/GB for excess transfer.
• The user base capacity varies significantly; Backendless scales to 0.25 M authenticated users, whereas Supabase tops out at 0.1 M users in its standard scaling path.

Choosing between these platforms comes down to the nature of your data and user growth. Backendless operates as a fixed-price BaaS, covering a PostgreSQL database, Auth, and Edge API functions within a predictable monthly bracket of $0.00 to $99.00/mo. This structure benefits teams that need significant storage headroom without the risk of an unpredictable bill. While Supabase also bundles its database and Edge API runtimes, its pricing model is far more aggressive, potentially reaching $7460.00/mo. Supabase relies on underlying AWS infrastructure, which makes it a familiar choice for engineers already embedded in the AWS ecosystem, but the lower included storage limits mean you will likely hit overage fees faster if your application handles heavy file uploads or large binary objects.

Backendless is the clear choice for applications requiring high storage volume and a large user base without the risk of extreme monthly fluctuations. Supabase remains the standard for developers who prioritize the specific Postgres-centric toolchain and are comfortable with a pricing model that scales exponentially as the application matures into a enterprise-grade footprint.
