The year 2021 was a golden era for Roblox script executors. Roblox was implementing stricter anti-tamper systems (Byfron was on the horizon, though not yet fully deployed), and many paid executors like Synapse X and Krnl dominated the market. Project Delta emerged as the "people's champion"—a free executor that could run complex scripts like Owl Hub and Noclip without constant crashes.
