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
