How we test

We are not a listicle farm. StackPicks runs its own funnels and its own newsletter on live accounts, so the reviews describe what the software is like to actually operate.

Every tool is scored on the same five criteria: value for money, free plan depth, ease of start, feature depth, and docs and support. Tools we have not operated yet are scored on published pricing and documentation, and labeled as such.
