5 free add-ons that level up Claude Code
Each one is free to download. Here's what each does, the official install command, and the honest catch.

What you need first
The 5 add-ons
FreeLLMAPI: run Claude Code on free AI models
Stacks the free plans of 30+ AI providers into one connection and switches to the next one when a limit hits. 32,000+ stars.
Easiest: download the desktop app (Mac .dmg or Windows .exe) from its GitHub Releases page, add your free provider keys, copy your one "unified key", then connect Claude Code:
npx freellmapi setup-claude --url http://localhost:3001 --api-key YOUR-UNIFIED-KEY
Tip: Catch: these aren't the top models, quality drops late in the day as free limits run out, and free plans may use your data. Keep private work off it.
Strix: AI that tests your own app for security holes
An open-source AI pentesting tool: agents try to break your app and suggest fixes. 67,000+ stars. Easiest way to use it from Claude Code:
npx skills add usestrix/strix
Tip: Catch: only ever point it at apps you own or have written permission to test. The full scanner needs Docker and an AI API key.
Claude-Mem: Claude remembers your past sessions
Saves what happened in each Claude Code session and brings the useful parts back next time, so you stop re-explaining your project. 98,000+ stars.
npx claude-mem install
Tip: Catch: the installer offers its hosted memory with a 30-day free trial and asks you to sign in. Want it fully local and free? Skip the sign-in (the README shows the --provider option). Don't use npm install -g, that installs only the library.
Agent Reach: lets your AI read the internet
Gives your AI agent ways to read YouTube, Reddit, X/Twitter, GitHub and more. Some sites need you to export your own browser cookies. 94,000+ stars. Paste this into Claude Code and it installs itself:
Install Agent Reach: https://raw.githubusercontent.com/Panniantong/agent-reach/main/docs/install.md
Tip: Catch: the main page is in Chinese (there's an English version in its docs). Cookies are logins, so only use a throwaway or low-risk account, and respect each site's rules.
claude-code-setup: Anthropic's own setup helper (official)
Looks at your project and recommends the right Claude Code helpers for it: hooks, skills, MCP servers and subagents. In Claude Code type:
/plugin
Tip: Then search claude-code-setup (by Anthropic) and install it. It's in Anthropic's official plugin directory, so it's the safest one to start with.
The catch
- Free to download isn't the same as free to run. Claude Code needs a paid plan unless you use FreeLLMAPI's free models.
- Install one at a time and check it works before adding the next.
- Only test your own apps with Strix.
- Add-ons run code on your computer. Stick to well-known ones like these, and read what each installer asks before you say yes.
