A threadbare Threads for web launches, works
Threads, Meta’s Twitter competitor, now has a web interface.

It’s currently no frills, no advertising on the sidebars, and you can work in multiple windows on different accounts if you know what you’re doing.
I seriously thought I would have at least three paragraphs worth of information to put in here, but other than noticing that depending on the account’s follower count the experience browsing is widely different.
