"Eth95.exe" is a browser-based interface which helps you interact with Smart Contracts. It's especially useful if you're dealing with Smart Contracts and dApps that don't have an official frontend.
Using it you can call different functions on different Smart Contracts, setup a custom signer and inspect events and log outputs.
Protip: Other than connecting via MetaMask you can setup a custom configuration or connect directly to your local Blockchain Network running on localhost:8545.
