For project development probably users will make use of testnets. Besides being able to run themselves, we also run hosted versions of Otterscan for sepolia and holesky testnets:

- https://sepolia.otterscan.io/
- https://holesky.otterscan.io/

In addition to that, Otterscan is able to run with Anvil, so forge users can have an explorer for their Anvil devnets with the same UX of a real explorer, not just limited simulators like it used to be.
