Mallow, our devs keep saying 'Server Authority went full release' like it's a big deal. I run marketing — why should a competitive brand experience care about an engine setting?
Mallow
Because it's the difference between a leaderboard people trust and one they don't. On July 9, 2026, Roblox shipped Server Authority to full release. In plain terms, it makes the server the single source of truth for your game's state and automatically rejects invalid client movements — the speed hacks and teleport exploits that wreck a competitive game. Cheat-resistance stops being a coding project and becomes an engine feature you switch on.
Marsh
'Server is the source of truth' — say that like I've never opened Studio.
Mallow
Normally a lot of a player's movement is decided on their own device and trusted by the server. That's convenient, but it's also how a cheater tells the server 'I'm running at 5× speed' and gets believed. Server Authority flips it: the server decides what's physically valid, and if a client claims something impossible, the server rejects it. The honest player never notices; the cheater's exploit simply doesn't take effect.
Marsh
If the server is checking everything, doesn't that make the controls feel laggy?
Mallow
That was the classic trade-off, and it's the clever part here. Server Authority uses client prediction and rollback: in Roblox's words, 'the client predicts the result of your inputs instantly, and if the server disagrees, the client corrects smoothly.' So your movement feels immediate, but the server still has the final say. You get fairness without the mushy input feel people associate with server checks.
Marsh
Is this something Roblox turned on for everyone, or do we choose it?
Mallow
You choose it — it's opt-in. Roblox was explicit that Server Authority 'isn't the right decision for all games', so it's always something you deliberately turn on. You enable it by toggling AuthorityMode to Server in the Workspace properties panel. That single switch auto-configures five settings it depends on — so it's not a giant migration checklist, it's one toggle that pulls the rest into place.
Marsh
What are those five settings? My devs will ask.
Mallow
Flipping AuthorityMode to Server enables: NextGenerationReplication, PlayerScriptsUseInputActionSystem, SignalBehavior set to Deferred, StreamingEnabled, and UseFixedSimulation. You don't have to hand-set them — the point is Roblox bundles the required foundation behind the one toggle so teams don't misconfigure it piecemeal.
Marsh
You said StreamingEnabled is one of them. I've heard that's a headache to add to an existing game.
Mallow
It can be, and Server Authority requires it. That's why Roblox shipped an experimental 'Instance Streaming Conversion Skill' — an AI tool that helps convert a non-streaming game to support streaming. It won't be flawless on a big legacy project, but it lowers the wall for teams that never turned streaming on. For a new brand experience, you'd design with streaming from day one and skip the migration entirely.
Marsh
Is there a fast way for our team to see it working rather than building from scratch?
Mallow
Yes — Roblox ships three template games built on Server Authority: Racing, Soccer, and Laser Tag. Those aren't just demos; they're working references for the three most common competitive shapes — a racer, a ball sport, and a shooter. If a client wants a fair, competitive brand experience, starting from the closest template is the fastest credible path.
Marsh
Any catches I should flag before we promise a client 'cheat-proof'?
Mallow
Two things. First, say 'cheat-resistant,' not 'cheat-proof' — Server Authority raises the floor dramatically but no system is absolute. Second, there are known limits at release: attributes are capped at 64 per instance, animations are limited to eight active tracks per Animator, and remote events don't have timeline synchronization. None of those are dealbreakers for most games, but your devs should design within them from the start rather than discover them late.
Marsh
So how do I actually use this in a pitch or a campaign?
Mallow
It's a trust story. For any competitive or leaderboard-driven brand experience — a branded racer, a tournament, a score-chase event — you can now say the game is fair and cheat-resistant using Roblox's own engine-level Server Authority, without commissioning a custom anti-cheat. That's cheaper for the client, faster to ship, and it's a claim built on a first-party Roblox feature rather than a third-party bolt-on. Fair leaderboards also protect your prizes and rankings — which matters the moment a campaign attaches real rewards to a score.
Marsh
And the technical-credibility angle for us as a studio?
Mallow
Big. Being able to say 'we ship on Server Authority with client prediction so it's fair and responsive' signals that your studio is current with Roblox's platform direction. For enterprise clients evaluating who to trust with a brand launch, 'we use Roblox's standard fairness feature correctly' is a reassuring, verifiable line — not marketing fluff.
Marsh
Give me the summary I can drop into a status update.
Mallow
(1) Server Authority went full release July 9, 2026: the server is the source of truth and auto-rejects invalid client movement. (2) It's opt-in — one AuthorityMode → Server toggle auto-configures five settings. (3) Client prediction + rollback keep controls instant. (4) Racing / Soccer / Laser Tag templates and an AI streaming-conversion skill lower adoption cost. (5) Mind the release limits (64 attributes, 8 animation tracks, no remote-event timeline sync). (6) Pitch line: fair, cheat-resistant competitive experiences with no custom anti-cheat.
Marsh
So Roblox turned 'stop the cheaters' from a custom engineering project into a toggle — and that's exactly the kind of thing that lets us promise a fair tournament without blowing the budget on anti-cheat. That I can sell.
