Self-hosted API proxy

Put retries and failover on a proxy you own

Downstream APIs fail. Your app should not. API Proxy Service is retries, rate limits, and failover as a process you run yourself.

API Proxy Service routing requests with failover

Most teams copy retry loops into every service or pay for a gateway they do not own. The useful work is almost always: call upstream, back off, trip a breaker, fail over. You do not need a monthly gateway for that if you can sit a proxy in the path.

What the proxy does

  1. 01

    Retry

    Automatic retries with exponential backoff when upstream flakes.

  2. 02

    Shape

    Rate limits and traffic shaping so a spike does not take the dependency down.

  3. 03

    Fail over

    Circuit breaker plus fallback routing to a secondary endpoint.

When a hosted gateway is the wrong default

Keep the gateway SaaS

You need org-wide identity, a shared mesh, or a control plane non-engineers already live in.

Run API Proxy

You want retries and failover on a host you run, in front of APIs you already call. One payment. No per-request tax.

After checkout, binaries and source land in your member files. The API Proxy product page has the license.

Setup is one process in the path

Pay once on Whop, download the binary from your member files, point your services at the proxy instead of the upstream. There is no account to create.

./api-proxy
  1. 01

    Download the binary from your member files.

  2. 02

    Put the proxy between your app and the upstream API.

  3. 03

    Set retry, rate limit, and fallback endpoints. Confirm metrics on the local dashboard.

Questions people ask before they switch

Is this an API gateway replacement?

For retries, rate limits, fallbacks, and circuit breakers in front of APIs you already call, yes. If you need a full mesh with org-wide identity, keep the gateway. This proxy is the reliability layer without a monthly bill.

Do I rewrite application code?

No. Put the proxy between your services and the upstream APIs. Retry, rate limit, and failover happen in the path.

Where does the data sit?

On the host you deploy. Metrics and routing stay local. There is no vendor sitting in the request path.

Do I need Kubernetes?

No. It is a lightweight, low-latency microservice. Run it next to the app that needs the shield.
