How to use it

Start from the decision,
not the directory.

Use the optimizer when you want a recommendation. Use compare when you already know the category. Use API pricing when your workload is programmatic.

01
Start from intent

Start with your workflow instead of browsing every tool one by one.

02
Compare the real cost

See realistic monthly cost, local tax, and free tiers side by side.

03
Verify before you buy

Check official provider pages before purchasing — plans change often.
