For the absolute beginner or non-technical user, the barrier to entry might be higher than a simple web-based tool.

• Initial Learning Curve: While the interface might be intuitive once set up, the initial process of getting it running could deter less technically inclined individuals.
• No “Always On” Convenience: Unlike a website, the local application or server needs to be running for it to be accessible, which might be an extra step for casual users.

These considerations highlight that while Stirling-PDF offers significant advantages, particularly for privacy and control, it requires a user who is either comfortable with a certain level of technical setup and maintenance or part of an organization with IT support to manage its deployment.

For those prioritizing ultimate ease of use and zero setup, a purely online or traditional desktop application might be a more straightforward choice, albeit with trade-offs in data sovereignty.
