Building a Comprehensive Reddit CLI Tool: From Basic Posting to Full Reddit Management with 33+ Commands

Building a Comprehensive Reddit CLI Tool: From Basic Posting to Full Reddit Management

๐Ÿš€ A complete journey from a simple Reddit posting tool to a professional-grade CLI with 33+ commands, Docker support, and comprehensive Reddit API integration.

The Problem

As a developer and Reddit enthusiast, I found myself needing to:

  • Post content across multiple subreddits efficiently
  • Monitor discussions and engage with communities
  • Research topics and find relevant subreddits
  • Manage my Reddit presence programmatically

Existing tools were either too complex, limited in functionality, or required extensive setup. I needed something that was both powerful and easy to use.

The Solution: Reddit CLI Tool

I built a comprehensive command-line interface that provides 33+ commands covering every aspect of Reddit interaction. Here's what makes it special:
