Runs your Docker build on your own machine before you push, so CI doesn't tell you the same bad news ten minutes later.
The Docker feedback loop is miserable. You push, you wait, CI builds for eight minutes, it fails on a typo in a COPY path, and you do it again.
dockgate moves that loop onto your machine. It builds before the push, and when the build fails it explains why in plain English instead of handing you 400 lines of daemon output.
It also notices when your Dockerfile has drifted away from your codebase, which is the failure that bites weeks later rather than immediately.
Click any stage to read what it does, or press the button to walk the whole thing.
v1 scope, written into the spec: no LLM or external AI API calls.
Every problem this tool solves is deterministic. A missing COPY path is a missing COPY path. There is no ambiguity to reason about, and no judgement call to make.
So the v1 scope says, in writing, that dockgate makes no LLM or external AI calls. It runs offline, it costs nothing, it needs no API key, and it returns the same answer every time.
I build AI systems most weeks. Knowing when not to reach for one is part of the same skill.
