Grigri+ vs grigri 2

Are there GriGri-like devices that support auto belay rather than assisted belay?
In general: No.
While some devices use mechanisms that can be different from the Grigri (in some cases radically different, such as the Wild Country Revo), all current sports climbing devices ...

Using Gri Gri 2 as a Self Belaying Device
We used GriGri extensively at my local wall for groups, route setting and emergency rescue in the wall. The key issue is that like a car seat belt a GriGri needs inertia to fire it - a sudden jerk. ...

Grigri+ vs grigri 2
I own a Grigri1 and a Grigri+, and I'm used to the Grigri2 too. To me Grigri+ is better. Positives: new materials, improved casing, no sharp edges, anti-panic handle, greater range of ropes can be ...

Using Gri Gri 2 as a Self Belaying Device
I have done this before, and it not all that different from jugging up a rope.

Why is it acceptable to belay from above with a grigri but not using the same movement from below?
I think it's more a question of positioning than anything.

Why do the GriGri and rope tie into different points on a rock climbing harness?

What are known failure modes of the auto-braking mechanism of Grigris?

Why do the GriGri and rope tie into different points on a rock climbing harness?
It is a question of design, rather than safety: You could make a safe harness with some other combination of loops for tying in and belaying, but the current combination is familiar and has some ...

Why do the GriGri and rope tie into different points on a rock climbing harness?
Other answers are good and one thing I would like to mention is ergonomics.
Thing about which way the grigri would face if was also clipped into the tie-in-points. The grigri would be sideways (that ...
