There isn’t really a perfect HDR equivalent to AutoStitch. HDR merging can be automated, but getting a natural-looking result usually still needs some human judgment during tone mapping. If the process is fully automatic, the result often ends up looking obviously “HDR,” which many people dislike.

If your goal is a simple, natural result, exposure blending tools may suit you better than classic HDR tone mapping. Enfuse is often recommended because it blends bracketed images without the typical HDR tone-mapping look, so there are fewer controls to tweak. If you use Lightroom, LR/Enfuse makes that workflow easier.

For more traditional HDR tools, commonly suggested options are Photomatix, Adobe Photoshop, and the free Luminance HDR.

If you also need stitching plus bracket handling, PTGui supports bracketed shots and can reduce the amount of manual work, especially for HDR panoramas.

So: yes, there are simpler options, but for the most natural results, exposure blending (such as Enfuse) is often closer to the “easy and good-looking” workflow you want than one-click HDR tone mapping.
