pretty sure Sans and Alphys are considered friends... i mean, there's a bucketload of evidence to support this, and this is off canon, not speculation. evidence includes:

epilogue (obviously)

dog-food bag favor (it's not like he would steal a dog food bag for no reason)

knowledge of the true lab

he and Alphys are hanging out and Alphys mentions him as 'a great guy' and even though all her friends are dead, she still has Sans (presumably keeping her alive and at least somewhat mentally stable, as ruling an entire population is stressful, and alongside her friends' death, it'd send her into a spiral without any emotional support. think of it like holding up a roof without walls or pillars. She also starts to say something "And with him around, I--... sigh") in the Alphys Ruler ending.

he and Alphys seem to both be able to read wing-dings (The blueprints in Sans 'lab' are the only ones found in game, and are in 'strange symbols'. It's unlikely they were written by Alphys, even with her terrible handwriting. Alphys also mentions using blueprints to use the determination machine, so that's probably another sans-alphys-true-lab thing), so they both probably worked together.

Alphys  literally knows Sans well enough to say Sans' jokes for him

but eh, it doesn't matter, now does it?
