What is Free plan?

A free plan is a tier of a product you can use without paying, usually with fewer features or a lower cap than the paid tiers. The split here is clean. 2FAS and addy.io both offer one. 12VPN, 1Password and Abine, Inc. do not, so a reader has to pay from the first sign-up. That matters most for short trials: a free tier lets you check the interface and the core protection on your own devices before committing, while a paid-only product forces the decision up front. Where a free plan exists, read the logging policy too, because the free tier and the paid tier can differ.
