KVProxy is designed to make secure mobile integrations feel ordinary.
It sits between your mobile app and the third-party APIs you already use. Your app sends requests without embedding real secrets. Your requests are routed to our backend, where KVProxy injects the required credentials securely and forwards the request to the upstream service; returning the response as if the app had talked to the provider directly.
From the client’s perspective, nothing unusual is happening. From a security perspective, secrets never touch the device.
Anything sent from a mobile app should be treated as public. Headers, query parameters, request bodies, and even values that appear to be obfuscated can be extracted and reused.
KVProxy is built around this assumption.
Instead of trying to hide secrets in the client, KVProxy keeps them server-side and applies them only when a request passes through the proxy. The app provides whatever non-sensitive values are needed to describe the request. KVProxy completes the request with the sensitive pieces at the last possible moment.
This shifts the trust boundary away from the device and back into an environment you control.
Your mobile app continues to make normal HTTPS requests.
Our mobile library routes your calls to a KVProxy endpoint, rather than the original third-party endpoint, and includes whatever headers, parameters, or body fields are required to describe the request. None of these values need to be secrets. If a request is inspected or replayed, there is nothing embedded in it that grants access on its own.
This keeps your client simple and avoids introducing custom protocols or SDK-level abstractions.
When KVProxy receives a request, it performs a small, well-defined set of operations.
First, it verifies that the request is allowed to use the proxy. This ensures that only authorized clients can trigger secret injection.
Next, it applies the configured credentials to the request. This may involve setting headers, adding query parameters, or modifying request bodies, depending on what the upstream API expects. These values are injected in memory and exist only for the lifetime of the request.
Once the request mutation is complete, KVProxy forwards it to the upstream service and streams the response back to the client. KVProxy does not persist request payloads, or responses as part of this flow.
Getting started with KVProxy is intentionally lightweight.
You begin by creating a project in the KVProxy dashboard. A project typically maps to a single application or environment, such as production or staging.
Within that project, you configure one or more proxy rules. Each proxy rule defines an upstream API, how requests should be transformed, and which credentials should be applied before forwarding.
At that point, server-side setup is complete. Once a proxy is created, our client library automatically reroutes your requests to the proxy endpoint.
Client-side changes are minimal.
With a single line of code, our client library is initialized and will do the work of automatically routing the affected requests to our backend. Requests that do not match the proxy rules are not routed and sent directly to the intended hosts.
The biggest advantage of this model appears after your app is in the wild.
Secrets can be rotated, revoked, or replaced entirely inside KVProxy without requiring a client update. Access can be disabled centrally if abuse is detected. Per-client rate limits help mitigate the cost of bad users. Changes take effect immediately and apply across all installed versions of your app.
This gives you long-term control over credentials in environments you do not control.
KVProxy is optimized for typical API requests made by mobile applications. It is not intended for large file uploads, media streaming, or bulk data transfer.
It also does not attempt to replace your backend or function as a general-purpose API gateway. If you already have a backend, KVProxy fits alongside it rather than competing with it.
Keeping the scope narrow allows KVProxy to remain predictable, reliable, and easy to reason about.
If you want to understand KVProxy’s guarantees and assumptions in more detail, the security documentation covers threat models and design tradeoffs explicitly.
If you are ready to try it, the Project Setup guide walks through creating your first proxy and testing it from a mobile client in just a few minutes.
The goal is simple: keep secrets off devices without turning a straightforward app into an infrastructure project.
