Features

Everything you need to ship leaner images

DockerLens handles the analysis so you can focus on shipping — not reading Docker documentation.

AI-powered analysis

Claude analyzes your Dockerfile and detects inefficiencies, security issues, and best practice violations instantly. It understands your stack — Node, Python, Go, Java, and more — and tailors every suggestion to your specific setup.

Security scanBest practicesLayer analysisBase image check

Visual diff

Side-by-side diff between your original and the optimized Dockerfile so you understand every change made.

Dockerfile.diff
·WORKDIR /app
−FROM node:18
+FROM node:18-alpine AS deps
·COPY package*.json ./
−COPY . .
−RUN npm install
+RUN npm ci --only=production
+FROM node:18-alpine AS runner
+COPY --from=deps /app/node_modules .
·CMD ["node", "server.js"]

Multi-stage builds

Automatically rewrites your Dockerfile using multi-stage builds to eliminate unnecessary layers.

Smaller images

Switches to Alpine, Slim, or Distroless base images. Typical reductions range from 60% to 90%.

Security fixes

Flags running as root, exposed secrets, outdated base images, and unnecessary packages.

Ready to copy

Get a production-ready Dockerfile with one click. No manual editing required.

How it works

Three steps to a leaner image

1

Paste your Dockerfile

Copy your existing Dockerfile — no matter how messy — and paste it into the editor.

2

AI analyzes it

Claude detects the base image, layer structure, security risks, and optimization opportunities in seconds.

3

Copy the result

Get a fully rewritten, optimized Dockerfile with a visual diff showing every change. Copy it and ship it.

FAQ

Frequently asked questions

Yes, during Beta all features are free. We plan to introduce a Pro plan with unlimited analyses after launch.

Yes, your Dockerfiles are stored so you can access your analysis history. We never share your code with third parties.

DockerLens uses Claude by Anthropic — one of the most capable AI models available. Results are reviewed suggestions, not automatic deployments. Always review before using in production.

Yes. DockerLens analyzes both single-stage and existing multi-stage Dockerfiles and suggests further optimizations when possible.

Any valid Dockerfile with a FROM instruction. DockerLens has specific knowledge of Node.js, Python, Go, Java, Ruby, Rust, and common Linux distributions.
