cm-proxy
cm-proxy provides a quick, cheap, secure, and straightforward serverless localhost proxy, useful for receiving webhooks from third-party services on a local development server. It is an inexpensive alternative to services such as ngrok or localtunnel.
We at CauseMatch integrate many external providers, including messaging services, donor funds, and over a dozen payment processors. Naturally, we process a lot of webhooks. Our engineers occasionally need to test those webhooks on a local development server. We don’t love exposing local ports on the big bad internet and we’ve had enough of expensive commercial solutions to a simple problem. So we built a proxy using dirt-cheap, pay-as-you-go AWS serverless building blocks. And we cancelled our ngrok subscription.
Our solution seemed so obvious, we’re surprised we didn’t find any similar utilities out there. So we’re making ours available. We hope others will find it useful. Drop us a line if you do!
