Welcome to KVProxy

KVProxy exists because mobile apps should never ship third-party API keys. Yet in practice, many teams still do.

Not because they don’t understand the risk, but because the alternatives are expensive, time-consuming, and operationally heavy. Building and maintaining a backend proxy just to protect a handful of secrets often means taking on infrastructure, auth, scaling, monitoring, and long-term maintenance that wasn’t part of the original plan.

KVProxy gives you a third option. It lets you protect API keys in mobile apps without forcing you to become a backend platform team.

The problem we’re solving

Mobile apps run in environments you don’t control. Anything shipped to a device can be inspected, extracted, or replayed; whether through reverse engineering, runtime inspection, or network interception.

When an API key leaks, the consequences tend to show up fast. Unexpected usage spikes, surprise bills, rate-limit exhaustion, or provider bans are common. Rotating keys is stressful, and pushing emergency client updates is even worse.

Most developers understand this risk. Many accept it anyway because standing up a proper proxy layer feels like overkill for what should be a simple problem.

KVProxy exists to remove that tradeoff.

What KVProxy does

At its core, KVProxy is a secure request proxy designed specifically for mobile clients.

Instead of embedding real secrets in your app, your client sends requests using placeholder values. KVProxy securely replaces those placeholders with real API keys on our backend and forwards the request to the third-party service. The keys never touch the client, never appear in your source code, and never get exposed in logs or crash reports.

The goal is not to sit in the middle of all your traffic or replace your backend. The goal is much narrower and more intentional: keep secrets off devices while preserving a simple, direct integration experience.

Why KVProxy is different

The usual advice is to “just use a backend.” That works, but it comes with a long tail of operational responsibility. Suddenly you’re managing uptime, scaling, authentication, observability, and on-call rotations: all to solve what started as a key-management problem.

On the other end of the spectrum are large, generic API gateways and AI proxies. They’re powerful, but often overbuilt for mobile use cases, hard to reason about, and opinionated in ways that don’t map cleanly onto client-side constraints.

KVProxy is intentionally narrow in scope. We focus on one job: protecting secrets in mobile apps, and avoid everything that isn’t required to do that job well. That focus translates into faster adoption, clearer security boundaries, and fewer moving parts to understand or maintain.

Our security philosophy

KVProxy is built on the assumption that client environments are hostile and that leaks are inevitable.

We operate from a zero-trust mindset: anything shipped to a device should be treated as public, and anything truly sensitive should remain server-side. Placeholder values used by clients are not reusable secrets, and access can be revoked centrally without requiring emergency app updates.

We also work to minimize blast radius. If something goes wrong, keys remain protected, and recovery does not depend on coordinating changes across thousands of installed clients.

Just as importantly, KVProxy is designed to avoid unnecessary data collection. We are not in the business of storing your request payloads or acting as a long-term data processor. Our role is to transform and forward requests securely, not to accumulate sensitive information.

How we think about operating KVProxy

KVProxy is intentionally built as a focused, sustainable product.

We prioritize reliability, clarity, and predictability over feature sprawl. Limits are explicit. Behavior is understandable. Pricing is straightforward. The system is designed to do one thing consistently well rather than many things unpredictably.

This also means avoiding lock-in and architectural hostage situations. You should be able to reason about how KVProxy works, why it exists in your stack, and what would happen if you ever decided to remove it.

Our goal is to earn trust over time, not extract it up front.

Who KVProxy is for

KVProxy is a good fit if you’re building a mobile app that talks directly to third-party APIs and you want strong security without standing up and maintaining custom infrastructure.

If you care about keeping secrets off devices, reducing operational overhead, and using tools that respect your time and attention, you’re in the right place.

What's next?

If you’re new here, the best next step is to read through how KVProxy works and walk through a basic setup. From there, you can dig into security details, limits, and pricing as deeply as you’d like.

We’re glad you’re here.
