I crafted this tool list for those looking to build truly life-changing systems with Claude Code.
If I could only have one tool list for building with Claude for the rest of 2026, this would be it.
Over the past 10 months, I've been using Claude rigorously across internal company workflows (7-figure companies), my personal systems, and more.
Simply put, these are the tools that have delivered the highest ROI across those systems, and many of my AI developers have used these.
In P.1, I outlined basic resources to help get you started with Claude Code.
Many people found it helpful, and I recommend reading it if you're new to Vibe Coding.
If you missed it, you can read it here.
Here, in part two, I will primarily focus on underrated tools and niche resources for advanced Claude users.
Beginners will definitely find value in these tools once you set up Claude Code and build a few mini projects - bookmark this guide for later if that's you.
