The tool that recommends tools — and isn’t paid to pick one.
Most GTM tools sell you the same generic data and the same generic score. StackSwap’s diagnostic tools are free, ungated, and modeled on real stacks — no vendor pays to win a comparison. The honest answer is “best for your situation,” even when that’s “keep what you have.” The one thing StackSwap does sell, openly, is the 42-skill Claude Code playbook below.

Why these tools
Each free tool reads a different angle of the stack: whether AI buyers can find and cite your site (AEO Audit), where your GTM spend overlaps and leaks (StackScan), the AI-native replacement for any tool you run (Swap), an opinionated stack to build from scratch (Stack Builder), and the same decision engine inside Claude or your own scripts (MCP + open API).
They’re all useful standalone, and they all run on the same engine — modeled on real stacks, never on commission. The audit will tell you to keep what already works.
