Docker Build Diff

See every file that changed between two builds.

Fully local: UI and Docker agent both run on this PC. Pulls and cache stay on disk — nothing is deployed to the cloud.

Checking local agent…

How it works

Everything stays on your machine.

  1. Download the kit

    Download the on-prem kit from Setup (served by this local UI) — UI + agent in one archive.

  2. Start on this PC

    Run ./start.sh. That starts the UI (:8765) and the agent (:8766) locally.

  3. Compare two builds

    Open http://127.0.0.1:8765, sign in to Hub, diff tags, download a .diff.

Setup

Download kits (local)

Needs Docker and Python 3.10+. You must be able to run docker ps. These packages are served by this local UI — share them with your team; each person runs on their own PC.

Web UI + agent kit

Recommended. Full on-prem package with UI, agent, and ./start.sh.

Download on-prem kit

Agent only

If the UI is already running and you only need the Docker agent.

Download agent
  1. Download the on-prem kit above.
  2. Extract it somewhere on this machine.
  3. In that folder, run:
./start.sh
# then open http://127.0.0.1:8765

Open the app unlocks only when the local agent is online (after ./start.sh). Stop later with ./stop.sh.
