About
What Relaymark is
Every product depends on APIs it does not control. Relaymark runs the calls your product actually makes, on a schedule, and tells you which one changed shape before a customer files a ticket.
Currently a concept built from a pattern we keep re-implementing on client work. If it earns its keep internally, it becomes a product.
What makes it different
Real calls, not pings
Checks exercise the endpoints and payloads your product depends on.
Contract drift detection
Alerts when a response shape changes, not only when it errors.
Alerts that point somewhere
Every alert names the call, the change, and the last good response.

Building something like this?
We take on app and game projects for clients using the same process we run on our own titles.
