CDEV is a game and software studio founded by Constant Suchet in France. Its Roblox games have passed 20 million visits, and its first software product, Prior, runs on five platforms.
Games and software, from prototype to the next update.
00 — The studio
CDEV designs game loops, systems and interfaces, then stays at the controls after launch: events, fixes, balancing. On the software side it's the same method with Prior, improved release after release.

04 — Roadmap
Towards a studio that creates and runs its own games.
- Today
Roblox games built with content creators, and Prior in production. That's where the studio built its technical base and its live-ops experience.
- Next
Original games under the CDEV brand: prototyped, tested with players, released and run by the studio.
- Then
Grow the team with specialised profiles (3D, VFX, UI) and explore platforms beyond Roblox.
Studio goals, with no announced dates.
