Calljmp is a secure, mobile-first backend platform built specifically for developers working with React Native and Flutter.
Unlike traditional web-first backends, it prioritizes mobile environments from the ground up, offering a faster, more secure development experience with minimal configuration.
Authentication is built-in and supports email/password as well as Google and Apple sign-ins. It includes advanced security features like brute-force protection, IP challenges, and email hygiene filters, all optimized for mobile app flows.
The database is powered by Cloudflare D1 - a globally distributed, SQLite-compatible engine - and includes full SQL support, row-level permissions, and a visual Studio to manage schemas, queries, and access rules with ease.
File storage is handled through Cloudflare R2, offering S3 compatibility and edge-speed performance. Permissions are managed through the same tag-based roles used across the platform, ensuring consistency and fine-grained control.
For backend logic, Calljmp uses Cloudflare Workers to deploy edge functions with near-instant global availability. Developers define simple REST endpoints, with automatic access to auth context, storage, and database resources.
The CLI enables seamless local development, schema migrations, and function deployment - removing the need for manual DevOps or external tooling. Everything is optimized to get mobile apps from prototype to production faster.
