Xcellent

Free X growth tool that runs as a local web app in your browser. No cloud, no database, no login, no subscription. Everything stays on your machine.

Important: Xcellent is a web-based dashboard that runs on localhost. When you start it, it launches a local web server and you access it at http://localhost:3848 in your browser. It is NOT a CLI tool — it has a full visual UI with charts, tables, and interactive features. Always open the browser URL after starting the server.

What It Does

1. Dashboard — Follower growth, impressions, engagement rate, profile visits
2. Analytics — Per-tweet performance, sortable by impressions/likes/engagement
3. Niche Discovery — Find accounts and trending content in any niche
4. AI Tweet Writer — Generate tweets in the user's voice, with style options
5. Best Posting Times — Calculated from the user's actual tweet data
6. Credit Monitor — Real-time X API usage tracking in the sidebar
7. Scheduling — Post via Postiz integration (optional)

Quick Start

# Clone the Xcellent repo

Then open http://localhost:8080 in the browser.
