What the data tells us

Key capabilities you'd miss

These are the features that typically drive the final decision — check whether your workflow depends on any of them before committing.

What company size tells you

1Password (201-500 employees) has the engineering bench to ship features across many fronts but may iterate slower on individual requests.
