As @Gunner said, there are, or there’s the ESP32 option.
However, it might be better to look at using multiple ESP8266 devices. I find that it’s very rare that all of the sensors, relays etc that you want to control area actually in the same physical location. If this is the case then the project lends itself to using multiple ESPs in different locations.
Even if all of your sensors etc are in the same location, there’s often something to be said tor taking a modular approach to the hardware configuration. This can make it a bit harder to set-up in the first instance, but easier to diagnose and troubleshoot issues in the future - when something stops working. It also make scalability easier, as when you run out of available points on one device, you just add another alongside it.
Also on the subject of available pins on the ESP8266, you have fewer than you think anyway. You should read this:
