Roblox Server Browser Script May 2026

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local TeleportService = game:GetService("TeleportService")
local DataStoreService = game:GetService("DataStoreService")
local Players = game:GetService("Players")
local function RefreshServerList()
-- Fetch all keys from DataStore (Use OrderedDataStore for efficiency)
local pages = serverStore:ListKeysAsync()
local servers = {}
for page in pages do
    for key in page do
        local data = serverStore:GetAsync(key)
        local decoded = HttpService:JSONDecode(data)
        table.insert(servers, decoded)
    end
end
-- Sort by player count (Descending)
table.sort(servers, function(a,b) return a.Players > b.Players end)
-- Populate UI here...

end
-- The Join Function
local function JoinServer(JobId)
local placeId = game.PlaceId -- Must be the same place
TeleportService:TeleportToPrivateServer(placeId, JobId, Players.LocalPlayer)
end
-- Bind refresh button
script.Parent.RefreshButton.MouseButton1Click:Connect(RefreshServerList)
 Roblox SERVER BROWSER SCRIPT

Note: The above is simplified. A production script must handle DataStore throttling, use OrderedDataStore for sorting, and implement ReservedServer access codes.

(Note: use only permitted APIs and respect Roblox Terms of Use.) end -- The Join Function local function JoinServer(JobId)

Scripts that aggressively fetch server data can trigger HTTP 429 (Too Many Requests) errors. A poorly coded server browser can soft-lock the user's IP from Roblox services temporarily. Modern scripts implement wait() delays or "throttling" to mimic human behavior and avoid detection by Roblox's anti-abuse systems.

TeleportService:TeleportToInstance(placeId, jobId, player) is the key function. However, the target server must not be shut down or full at the exact moment of teleportation. To mitigate this:

For games with thousands of concurrent servers, a single DataStore or API endpoint becomes a bottleneck. Implement regional proxies and shard server data by geographical zone. Clients query the proxy nearest to them. Note: The above is simplified

For developers wanting total control, here is a minimal viable script structure. (Note: This is pseudo-code to illustrate the logic).

Every active server must "advertise" itself to a central database. Every 30-60 seconds, the server sends a heartbeat to a DataStore or a custom API.

| Feature | Method | |--------|--------| | List active servers | HttpService + custom game server tracking | | Show player count | Store in DataStore / MemoryStore | | Join specific server | TeleportToPrivateServer with access code | | Filter by region | Store server region on creation | | Password-protected servers | Private server links + codes |
