Rivrs Tech Stack

UGC game studio building on Roblox, Minecraft, and Fortnite

Computer Games Rennes, Bretagne 11–50 employees Founded 2021 Privately Held

Rivrs is a UGC game studio (11–50 employees, Rennes-based, founded 2021) developing multiplayer games on top of existing platforms like Roblox and Minecraft rather than building custom engines. The tech stack reveals a creator-first workflow: Luau/Lua scripting, Roblox Studio, plus Adobe/CapCut/Runway for content production and distribution across TikTok/YouTube. Active adoption of Unreal Engine and Unity signals expansion beyond Roblox—hedging platform risk. Hiring is marketing-heavy (4 roles) relative to engineering (3), with accelerating velocity (7 placements in 30 days), consistent with a studio scaling creator partnerships and influencer ops rather than engine development.
