The four kinds of free
Complete product, metered on something else. Everything works; a specific resource is limited or a specific expensive capability is metered. This is the most durable kind because the vendor has a real revenue model that does not depend on frustrating you.
Feature-limited. Core functionality works, advanced features are paid. Legitimate, and the question is whether the limits sit inside or outside what you need.
Usage-limited. Full features, capped records, users, or storage. Fine if the cap is generous relative to your size, and a countdown if it is not.
Trial with no clock. Nominally free, deliberately crippled so that real use is impossible. The tell is that basic operations are restricted rather than advanced ones.
What to check before building on one
Business models that sustain free
Usage-based pricing on the expensive part. Hosting records costs the vendor almost nothing; AI processing has real marginal cost. Charging for the latter and not the former is coherent and durable. This is the Brainis model: all 11 modules on every plan, AI work metered in credits.
Upsell to scale. Free for small teams, paid at size. Works when the free tier is genuinely useful, and becomes a trap when the size threshold is low.
Free tier as marketing. Sustainable while the vendor is funded, and the first thing cut when priorities change. Treat these with more caution.
Important: The question is not whether free is real today. It is whether the vendor's revenue model depends on the free tier staying good. When free users cost the vendor little and paid users pay for something genuinely different, free is stable.

FAQ
Is free software safe for business data?
Free versus paid is not the relevant axis. Ask about encryption, permissions, audit, retention, and data use, and evaluate the answers regardless of price.
Should we pay anyway for support?
If uptime and support responsiveness are business-critical, yes. That is a real difference worth paying for and a legitimate reason to be on a paid tier.
What is the catch with Brainis?
Plans start at $29 a month and include every module with no per-seat cost; AI work consumes credits on top. The catch, stated plainly, is that heavy AI use costs more, and the Free tier is small on purpose. See how Brainis pricing works.
