# Programs with Anchor (default choice)

**Source**: https://solana.com/programs-anchor.md

## When to use Anchor
Use Anchor by default when:
- You want fast iteration with reduced boilerplate
- You want an IDL and TypeScript client story out of the box
- You want mature testing and workspace tooling
- You need built-in security through automatic account validation

## Core Advantages
- **Reduced Boilerplate**: Abstracts repetitive account management, instruction serialization, and error handling
- **Built-in Security**: Automatic account-ownership verification and data validation
- **IDL Generation**: Automatic interface definition for client generation
