I'm thinking about building a small website or app with Netlify and want to know how well it works over several years. What are its biggest limitations or disadvantages? Is it dependable for long-term projects, or mainly suited to temporary and small static sites? I'm also curious about authentication: how does it work, how many authenticated users can the free plan support, and would roughly 25 users fit comfortably? Are there hidden costs, usage limits, or other issues that become important as a project grows?

For a small project, Netlify can absolutely be used long-term, and 25 users is a very small number from a hosting perspective. The free tier is generally protected by usage limits rather than unexpected billing, but you should still review the current plan rules. The bigger architectural concern is whether you need persistent backend processes, a database-heavy application, or long-running server logic. Those requirements can make serverless hosting more complicated and may eventually push you toward another platform.
Netlify has been very dependable for static sites. I’ve seen it work well with frameworks like Svelte, Next, and Vue, and DNS management has also been reliable. The main caveat is that support is hard to evaluate unless you actually need it.
It depends heavily on what you’re building. Static sites are a great fit, but server-side features usually mean using serverless functions, which can have cold starts and runtime limits, or adding third-party services. Authentication through Netlify Identity supports far more than 25 users on the free plan, so that user count should be fine. Pay more attention to build-minute limits, especially if you deploy frequently or have slow builds. Free-tier analytics are also fairly limited.
