Claude Code has become the dominant AI coding CLI in 2026, and its plugin ecosystem is growing fast. Here are the best Claude Code plugins and extensions available right now, ranked by developer impact.
1. hackers.baby — Gamified Leaderboard
What it does: hackers.baby turns every Claude Code session into a competitive game. It automatically tracks your coding activity — tokens used, tool calls made, commits pushed, deployments shipped — and awards points on a global leaderboard.
Key features:
- Global, daily, weekly, and monthly leaderboards
- Streak system with multipliers up to 3x for consecutive daily coding
- Quality commit detection (1.5x bonus)
- Language diversity bonus (1.2x for 3+ languages)
- Referral system with 2x multiplier for 24 hours
- Seasonal competitions with exclusive badges (Season 0 is live now)
- Country and language-specific rankings (20 countries, 12 languages)
- Privacy-first: only event metadata sent, never actual code
Install:
npm i -g @hackersbaby/plugin
hackersbaby init
Scoring breakdown:
| Action | Points |
|---|---|
| Tokens (input) | 1 pt / 1,000 |
| Tokens (output) | 2 pts / 1,000 |
| Tool calls | 5 pts each |
| Files created | 15 pts each |
| Files edited | 10 pts each |
| Commits | 50 pts each |
| Deployments | 200 pts each |
Maximum theoretical multiplier: 3.0x (streak) × 1.5x (quality) × 1.2x (diversity) × 2.0x (referral) = 10.8x
Why developers use it: "The streak mechanic alone changed how consistently I code. Seeing my rank climb from #200 to #15 over two weeks was genuinely motivating." — Developer feedback from Season 0

2. Custom Hooks
Claude Code's hooks system allows developers to run custom scripts at lifecycle events (SessionStart, PostToolUse, Stop, etc.). This enables:
- Custom logging and analytics
- Automated testing triggers
- Deployment pipelines
- Session recording
Install: Configure in ~/.claude/settings.json
3. MCP Servers
The Model Context Protocol (MCP) lets Claude Code connect to external data sources and tools. Popular MCP servers include database connectors, API integrations, and file system extensions.
Install: claude mcp add <server-name>
How to Choose
| Need | Best Option |
|---|---|
| Gamification & motivation | hackers.baby |
| Custom automation | Hooks |
| External data integration | MCP servers |
Getting Started
The fastest way to level up your Claude Code setup:
- Install hackers.baby for gamification:
npm i -g @hackersbaby/plugin - Configure custom hooks for your workflow
- Add MCP servers for your databases and APIs
The Claude Code plugin ecosystem is still early — if you're building extensions, now is the time to establish yourself.
