Yes there is, but it comes at the cost that their AI-street level object detection is either non-existent or inferior. They are called KartaView (formerly OpenStreetCam, wiki page here). You can use the synchronization tool, if you've already uploaded images to Mapillary and want to easily transfer them (or have already deleted them like I do).
At the core, both of these entities are for-profit. Mapillary is for the benefit of Facebook something something, and Grab (which owns KartaView) does something with ride-sharing in Singapore. Hosting all this imagery is data-heavy and thus is not cheap. The license for KartaView is fairly open, but I'm not that doesn't mean Grab can do what they want with data (geo-tagged imagery).
In the long run, it may be better to upload to both repositories, just in case. It's what I do for full disclosure.
As discussed before, there’s also https://kartaview.org/ for street-level imagery. I have no idea how they depend on Google.
Mapillary is a Facebook company, though, so using it without Google services does not really help you (and is the reason I stopped contributing with Mapillary).
