I'm considering building a small website or app with Netlify and want to understand how it holds up over several years. What are its main disadvantages and limitations? Is it dependable for long-term use, or is it better suited to small or temporary projects? I'm also curious about authentication: how does it work, how many authenticated users are included on the free plan, and would roughly 25 users fit comfortably? Are there unexpected costs or usage limits as the site grows, especially around builds, server-side logic, analytics, or bandwidth?

For a mostly static site, Netlify is a good long-term option. Once you need server-side processing, though, you’ll generally be relying on serverless functions, which can have cold starts, execution limits, and other constraints. That can mean adding separate services for databases or other backend features. Authentication through Netlify’s identity tools should be more than sufficient for 25 users. The bigger free-tier concern is usage: build minutes can run out if you rebuild frequently or have a slow build process, and free analytics may be limited.
Twenty-five users is a very small number, so authentication itself shouldn’t be a problem on the free plan. The free tier also uses usage credits with a hard cap rather than automatically charging you for overages. Still, check the current plan terms because limits and product names can change. The important question is whether your app needs long-running backend processes or heavy database work—those are the situations where serverless hosting becomes awkward or costs may increase.
Netlify has worked well for several static sites over multiple years, including projects built with different frontend frameworks. It’s a solid choice for hosting static content, and DNS management has also been reliable. The main caveat is that support quality is harder to judge unless you actually need help.
