StackPick decision test

Don't switch until you can name the problem you're solving.

Write down the friction in your current tool, reproduce it, then run the same workflow in each alternative. Compare setup effort, daily clicks, integrations, migration, limits and the first feature you would need to pay for.

StackPick verdict

The bottom line.

Switching only makes sense when the alternative solves the specific problem that made you look elsewhere.
