Build apps, not backends
Calljmp is a backend platform designed for mobile developers. We remove the complexity of infrastructure, letting you focus on building great experiences for your users — not managing servers, databases, or auth flows.
Our mission
To empower mobile developers with simple, secure, and scalable infrastructure that works out of the box — without needing to build or maintain backend code.
We believe that infrastructure should be invisible. Our goal is to make mobile-first development seamless by offering secure authentication, cloud functions, database access, and storage — all accessible from a single SDK and CLI.
- Projects using Calljmp ship MVPs in half the time compared to teams building custom backends.
- 2x faster
- Built entirely on Cloudflare’s global edge network, Calljmp ensures low latency for your users worldwide.
- 99.99% edge uptime
- Calljmp manages infrastructure, keys, and data access securely by default — so developers don’t have to.
- 0 leaked secrets
What We Believe
We believe developers should spend more time building, and less time managing infrastructure.
- Backends should be invisible — You shouldn't need to think about tokens, servers, or setup.
- Security should be default — Not an afterthought. Auth, access, and encryption must be built-in.
- APIs should be native — Mobile developers deserve first-class tools, not web-centric afterthoughts.
- Simplicity scales — Fewer decisions means fewer bugs, fewer costs, and faster time to ship.
We’re building Calljmp around these beliefs — and listening closely to the developers who depend on us.
Our Story
Calljmp was born from frustration — frustration with setting up backends again and again for mobile apps. As developers, we loved building great user experiences, but we kept running into the same roadblocks: complex authentication, database setup, deployment scripts, and boilerplate infrastructure.
We wanted something simpler. Something mobile-first.
So we built it.
Calljmp started as a tool to help us move faster. Now, it’s a backend platform designed for mobile developers everywhere — simple, secure, and scalable out of the box.
Our values
We’re developers building for developers. These are the principles that guide our work:
- Simplicity over configuration
- We believe great tools should work without setup. One CLI, one SDK, one endpoint.
- Security-first by design
- Infrastructure should protect developers and users by default — not rely on afterthoughts.
- Mobile comes first
- We’re optimized for native SDKs, fast startup times, and mobile scale from day one.
- No hidden complexity
- Clear quotas, transparent billing, predictable behavior. You always know what you’re building with.
- Trust through transparency
- We share what we’re building, how it works, and why decisions are made.
- Iterate fast, stay focused
- We ship improvements weekly and treat developer experience as our north star.
Our team
We're a small, focused team with deep experience in mobile and backend infrastructure. We've worked at big tech companies, built tools for startups, and launched global-scale systems — now we're building the platform we always wanted.
