# DeployDiff CLI

[](https://github.com/Coding-Dev-Tools/deploydiff/stargazers)

Preview infrastructure changes with human-readable diffs, cost impact estimation, and rollback commands — before you hit deploy.

> ⭐ **Star this repo** if you manage infrastructure — it helps other devs find DeployDiff!

## Installation

```bash
pip install deploydiff
```

Or install the latest version directly from GitHub:
```bash
pip install git+https://github.com/Coding-Dev-Tools/deploydiff.git
```

Or install via Homebrew (macOS/Linux):
```bash
brew tap Coding-Dev-Tools/tap
brew install deploydiff
```

Or install via Scoop (Windows):
```bash
scoop bucket add Coding-Dev-Tools https://github.com/Coding-Dev-Tools/scoop-bucket
scoop install deploydiff
```

## Usage

```bash
# 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:

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

## CI/CD Integration

```bash
# 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:

```bash
# 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
```
