Scarlet Executor is the go-to choice for users running multiple Roblox instances simultaneously. Full multi-instance support allows a single Scarlet installation to attach to and independently control up to four concurrent Roblox processes, each with its own script execution queue and output console. Level 8 engine, keyless access, and a 2,000+ script hub complete the package for advanced multi-session workflows.

Running multiple Roblox instances simultaneously is a common approach for users who want to run farm scripts across multiple accounts. Most executors handle this poorly, either crashing when a second instance is detected or only controlling the most recently attached process. Scarlet was built with multi-instance as a first-class feature from the first line of code. The instance manager panel displays each active Roblox process as a separate card showing game name, attachment status, and last executed script. Each instance has an independent script editor and output console accessible by clicking its card. Scripts can be broadcast to all attached instances simultaneously with a single button, or executed selectively on specific instances. The attach engine handles concurrent injection into multiple processes without the state conflicts that cause crashes in single-instance tools. Up to four simultaneous instances are supported, covering the majority of multi-account workflows. The Level 8 engine runs independently for each instance with no shared state between sessions.
