It's open source. I'm open to seeing how we might be able to integrate or work with Effe in our Go SDK, or if necessary, learn from your effort. Take a look at https://github.com/iopipe/iopipe-golang, I'd love a pull-request.

We're not an alternative to AWS Lambda or, "Lambda on your own infrastructure". Instead, we desire to make it easier to build apps that run anywhere, which includes both AWS Lambda and Docker. I suppose there's some overlap, but the goals and technical challenges are a bit different. IOpipe is also a library that simplifies integration with services that provide state.
