Usage

# Preview infrastructure changes
deploydiff preview --tf plan.json
deploydiff preview --cfn changeset.json
deploydiff preview --pulumi preview.json
deploydiff preview --tf plan.json -v  # verbose: before/after details

# Estimate cost impact
deploydiff cost --tf plan.json
deploydiff cost --cfn changeset.json
deploydiff cost --tf plan.json --pricing custom-pricing.json

# Generate rollback commands
deploydiff rollback --tf plan.json
deploydiff rollback --cfn changeset.json

# Run as MCP server (for AI agent integration)
deploydiff mcp

What You Get With preview

• Resource summary: count of creates, updates, deletes, and replaces
• Property-level diffs: what changed, from what to what
• Destructive action highlighting: replaces and deletions called out
• Multi-provider: Terraform, CloudFormation, Pulumi from a single CLI

What You Get With cost

• Cost impact estimate: before vs. after per resource
• Provider-native pricing: reads Terraform/CFN cost metadata
• Summary row: total monthly change

What You Get With rollback

• Generated rollback commands: reverse the last plan
• Provider-specific: correct syntax for Terraform, CloudFormation
• No manual command construction: eliminates panic-mode mistakes

MCP Server Mode

DeployDiff can run as an MCP (Model Context Protocol) server, letting AI coding agents like Claude Code and Cursor interact with your infrastructure diffs directly:

# Start MCP server (requires click-to-mcp)
deploydiff mcp

CI/CD Integration

# Preview changes in CI pipeline
deploydiff preview --tf plan.json

# Check cost impact before deploy
deploydiff cost --tf plan.json

# Generate rollback commands for rapid recovery
deploydiff rollback --tf plan.json

Combine with shell scripting for pipeline gating:

# Gate on destructive changes (check preview output for destroy actions)
deploydiff preview --tf plan.json | grep -q "destroy" && echo "WARNING: Contains destructive changes!"

# Check cost impact (use --pricing for custom pricing data)
deploydiff cost --tf plan.json --pricing custom-pricing.json
