Why would you want multiple Roblox instances? Here are a few practical reasons:
Fast Flags are special configuration settings that control how Roblox behaves on your computer. Fishstrap uses these to unlock performance improvements, remove limits, and give you more control over your experience.
fishstrap-multi-instance includes recommended Fast Flag presets that are tested and known to work well for multi-instance setups. You don’t need to know the technical details — just run the tool and it handles everything for you.
Yes. This is a completely free and open-source project. Because the code is public, anyone can examine it for security issues. It’s a community tool made by users, for users. However, always download from the official GitHub page linked above to avoid modified or malicious copies.
Using multiple Roblox instances is not against Roblox’s terms of service on its own. However, any automation or cheating is not allowed. This tool simply lets you run multiple instances manually — it does not automate gameplay or modify game files. As always, use common sense and respect Roblox rules.
No, this project is specifically for Windows. It’s mentioned right in the project title. If you’re on Mac or Linux, you’ll need to look for alternative solutions or try running Windows in a virtual machine.
