Are there any good alternatives to Backpage

Backpage before its seizure was the second biggest platform for classified ads. It was second only to Craigslist and it came to prominence after CL closed its adult services section. Soon after that, Backpage took the chance to fill that gap and make some real money out of it.
The truth is that Backpage made really big money out of sex trafficking ads. It is rumored that it made more than $100 million in revenue per year. Of course, all that was illegal and 7 years later, in 2017 it was seized by the federal law authorities. More than 100 people associated with Backpage sex ads were arrested and 8 of the website's officials were prosecuted.
The shut down of Backpage created a huge gap in the niche as the demand and supply for sex employment is still there. While prostitution is still illegal in the vast majority of the United States, the supply and demand are there. This means that sooner or later someone will try to fill that gap, it is simple law of economy.
The reality is that there are already some websites and platforms that have tried to fill that gap but none of them has reached the success of Backpage. There are some promising ones such as Ohlala app but they are still too small comparing to their predecessor and most of them are operating locally only to states that prostitution is allowed such as Nevada in order to avoid the fate of Backpage.
If you are indulged to travel abroad your options are multiplied vastly as the laws about prostitution in different continents such as Europe, Asia or even South America and much more tolerant towards sex workers than the U.S. ones. If you are willing to pay for sex, a trip to Amsterdam would probably be the best thing to do at the moment.
Of course, there are a few more platforms that are trying to fill Backpage's shoes in the continental U.S. but most of them are either unreliable with low population or full of scammers that would do anything to take your money away. We strongly believe that sooner or later there will be a platform that will take over the niche and provide a safe haven for sex workers but at the moment we would advise you not to try to find any prostitutes online. It is much more likely that you will end up losing your money rather than finding what you are looking for.
