Our lead project · early prototype
REPLAYLAB
Don’t watch playtests. Replay them.
Every session becomes a simulation you can rewind, question and prove. The first viewer already runs on a real race.

VECTVR is an independent studio in France. We build ReplayLab, a lab that turns playtests into replayable evidence, and AccoBolide, the racing game we test it on.

Our first game · in development
ACCOBOLIDE
The road is the race. The verge is the game.
An arcade racer with road-maintenance tractors, and the toughest customer ReplayLab will ever have.

A game sessionisn’t a video.It’s a simulation.Run it again.

Same seed, same inputs, same race. Every time.
In our own game, an eight-tractor race replays to the bit and checks itself against a final state hash. That changes everything you can do with a playtest, so we are building the tool around it.
Proof, not promises
BUILT INSIDEA REAL GAME.
ReplayLab starts where our own production starts: a deterministic racing simulation with a diagnostic export. The numbers below come from one archived automated race.

The studio
SMALL STUDIO.SHARP TOOLS.
VECTVR is an independent studio founded in France in 2026 by Victor Giroud. We build tools for the people who make games, and we make games to keep our tools honest.
Evidence over vibes.
Every claim we make about a game, or a playtest, should point to a moment you can replay.
Dogfood first.
Nothing ships in ReplayLab until it has survived a week of AccoBolide production.
Players are co-authors.
What a player says belongs next to what the player did, on the same timeline.

PLAYTEST OFTEN?LET’S TALK.
hello@vectvr.comWe are looking for a few studios who run regular playtests and want to shape ReplayLab around their real problems. Or just say hello.
