The Isle Server Config Generator
Build a clean Game.ini and Engine.ini for your The Isle: Evrima dedicated server. Every setting explained in plain English, a per-dino AllowedClasses picker with a bundled dino dex, and the finicky section casing baked in so Evrima doesn't quietly ignore your whole file. No login, no host paywall, and no half-broken template someone copied off a forum three patches ago.

Server Identity
Name, password, size, map. This is what players see in the browser before they ever spawn in, so it's the first thing that gets you clicked or skipped.
The name in the server browser. Make it searchable — people filter by it. "Semi-RP 2x Growth · Adults Only" beats "server1" every time.
Turn this on to gate the server behind a password. Off = anyone can walk in. Does nothing on its own — set the password below too.
The actual password players type to join. Does nothing unless "Password-Protect Server" above is on.
Concurrent player cap. Higher needs more CPU/RAM — don't cap higher than your box can actually feed, or the whole server chugs at peak.
Gateway (Isla Spiro) is the only official Evrima map right now. Leave it unless you're running a custom map you know the name of.
Join Queue
What happens when the server's full. Let latecomers wait in line instead of bouncing off a hard reject and wandering off to someone else's server.
On = full-server arrivals get a queue slot instead of a hard reject. Leave it on — bouncing players just makes them join a competitor.
TCP port for the queue. Usually auto-assigned by your host — only touch it if you're self-hosting and know your port map. Leave blank otherwise.
Gameplay & World
The knobs that actually change how the world plays: growth speed, day length, weather, humans. This is where your server stops being "default" and starts being yours.
How fast dinos grow from juvenile to adult. 1 = default grind, 0.5 = hardcore slow, 2–5 = casual. Keep it under 20 or the growth system starts breaking.
Real minutes of daytime per cycle. Shorten for faster nights, lengthen for a slower, more exploratory world.
Real minutes of night. Night is when the map gets dangerous — tune to taste. Shorter nights = a gentler server.
Dynamic weather on/off. (Note: rain particles were temporarily pulled in 0.21.720, but the weather system itself still runs.)
Off = no fall damage. Beginner servers often disable it so nobody rage-quits after a cliff; hardcore keeps it honest.
Turns on the playable human game mode. Off by default — most dino servers leave it off.
Spawns edible plants for herbivores. Turn this off and your plant-eaters starve — leave it on unless you really know why you don't want it.
Server-side replay recording. Off by default; costs disk if you enable it. Nice for clip creators, unnecessary for most.
Global text chat across the whole server. Off forces local-only comms — the standard immersion move on RP servers.
AI Creatures
Non-playable critters and prey. This is the single biggest performance lever on the whole server, so tune it here before you go blaming your box or your host.
Master switch for all AI creatures. False = a completely empty world with no huntable prey. Herbivore-only servers sometimes still want this on for ambience.
How much AI spawns around players. This is the #1 thing that hurts performance — raise it carefully and watch your frame time, don't just crank it and hope.
Seconds between AI spawn checks. Lower = AI repopulates faster (heavier on the server); higher = leaner but you'll notice thinner herds.
Block specific AI species from spawning — same finicky casing as AllowedClasses. Enter a single class name here (advanced; leave blank for none).
Turns on migration zones — the roaming areas that set herbivore diets and push movement across the map. Core Evrima gameplay; most servers keep it on.
Seconds a migration zone stays active (5400 = 1.5h). Shorter zones = more churn and more movement across the map.
Mutations
The Evrima trait/mutation system for growing dinos.
Turns the mutation system on or off server-wide. Off = a flat, no-trait experience where every dino of a species is identical.
RCON
Remote admin console. How you kick, ban, and run commands without having to be logged in as a dino at the time.
Turn on RCON so external admin tools can connect. Off by default — enable it if you moderate remotely or run a Discord admin bot.
TCP port RCON listens on. Often auto-assigned by the host; set it yourself only if you're self-hosting. Only matters when RCON is on.
Use a strong one — this is full admin control of your server. Never reuse your game password. Only emitted when RCON is enabled.
Admins & Whitelist
Who has power and who's allowed in. Heads up: this lives under the [/Script/TheIsle.TIGameStateBase] section, a different header from everything above it, and Evrima cares about that.
Your admin's SteamID64. These players get in-game admin powers. (One ID here; for multiple admins, add extra AdminsSteamIDs lines in the Advanced box below.)
On = only whitelisted SteamIDs can join. The lock for private and RP communities. Off = open to anyone (subject to your password).
An allowed SteamID64. Only matters when the whitelist is on. Add more via extra WhitelistIDs lines in the Advanced box below.
Playable Dinos (AllowedClasses + dex)
The one everybody comes here for. Every dino you tick emits one AllowedClasses=<class> line, and here's the gotcha that trips people up: tick even one and only ticked dinos are playable (everything else is off). Tick none and the block stays empty, which means every dino is allowed. Each card shows the dino's diet and role from the bundled dex so you know what you're actually turning on.
Epic Online Services (Engine.ini)
The credentials that make your server actually show up in the in-game browser. These live in Engine.ini, not Game.ini, under the [EpicOnlineServices] header. Miss them and your server runs fine but nobody can find it.
EOS client ID. Required — without a valid [EpicOnlineServices] block your server never appears in-game. Use the current shared dedicated-server credential from the official docs.
EOS client secret, paired with the ID above. Required for the server to register with Epic and show up in the browser.
Advanced / Raw Game.ini Overrides
The escape hatch for lines the form doesn't have a field for: a second admin, more whitelist IDs, or a key we haven't surfaced yet. Paste one Key=Value per line and they get appended verbatim to the [/Script/TheIsle.TIGameSession] block. Watch the casing here. Evrima is unforgiving and won't tell you why it broke.
About The Isle Server Config Generator
The Isle is a survival dinosaur sim (Steam 376210), and every modern server runs the Evrima branch, the ground-up rebuild that replaced Legacy. Two files do the work. Game.ini holds gameplay: growth, AI, weather, and which dinos are playable, all under [/Script/TheIsle.TIGameSession] and [/Script/TheIsle.TIGameStateBase]. Engine.ini holds the [EpicOnlineServices] credentials your server needs to even show up in the in-game browser.
Here's the gotcha, and the entire reason this generator exists: Evrima is brutally picky about section headers and key casing. One wrong bracket or a lowercased key and the whole file gets silently ignored. Your server boots vanilla, no error message, and you're left staring at it wondering what you did wrong. This tool bakes the correct headers and exact casing in for you, then hands you two ready-to-paste files to copy or download.
What makes this different
Most The Isle config tools bolt a hosting funnel onto the page: a 30%-off banner, plan tiers, "Buy now" buttons wrapped around the settings you actually came for. This one doesn't. No login, no gate, no upsell. It's mobile-first (the dino picker and preview work one-thumbed on a phone), every setting has a plain-English tip, and it's dated: verified to Evrima 0.21.720 (July 2026). It also bundles something nobody else pairs with a config picker, an inline dino dex. When you pick which dinosaurs are playable via AllowedClasses, each card shows that species' diet and role, so you actually know what you're enabling instead of squinting at raw class strings and guessing.
How AllowedClasses works
AllowedClasses is a whitelist. Add one AllowedClasses=<Species> line per dinosaur you want players to be able to spawn as. Here's the catch that gets everyone: list any lines at all and only those dinos are playable. Everything you left off is disabled. Want a Tyrannosaurus-and-Deinosuchus-only apex server? List just those two. Want every dino allowed? Leave the block completely empty. The picker handles the exact class strings so you don't fat-finger one and quietly break your roster.
Where the files live
TheIsle/Saved/Config/WindowsServer/Game.iniandEngine.ini(Windows servers)TheIsle/Saved/Config/LinuxServer/Game.iniandEngine.ini(Linux servers)- Managed hosts (most panels): under "Configuration Files" or a built-in config editor
Stop the server before editing. Changes you make while it's running get overwritten on shutdown, so you'll swear you saved it and it'll revert anyway.
