How much does an Alchemy Factory server cost?

Pay-per-use starts at 0.0320 €/h for 4 GB of RAM, so a four-hour co-op session costs around 0.13 €. As a fixed plan it starts at 8.00 €/month, with term discounts of up to 20% for 360 days.

Does Alchemy Factory have a dedicated server?

Yes. With version 1.0 in September 2026, D5 Copperhead released an official dedicated server (Steam app 4550060). It's Windows only, around 413 MB in size and, according to the developer, still experimental.

What does "experimental" mean for the dedicated server?

The developer rates the server as experimental. According to D5 Copperhead, setting up the network connection can take several attempts, and the server then retries automatically (adjustable via session_retry_seconds). Expect changes with future patches and make a backup before bigger rebuilds.

How do my friends join the server?

Three ways: through the in-game server list or multiplayer lobby as long as server_public is set to 1, directly by IP and port from the panel (a domain works instead of the IP too), or with the join code from the server console.

Where do I find the join code?

In your server's console in the panel. After starting, the server prints a line with "join address: … join code: …". Pass that code on to your fellow players.

Does the server save when I stop it?

No. Alchemy Factory doesn't save on shutdown, so progress since the last autosave is gone after a stop or restart. By default the server saves every 5 minutes. The safest way is to stop it after everyone has left the game: with pause_when_empty it saves as soon as the last player leaves.

How many players can play on an Alchemy Factory server?

4 slots is the game default, and at RespawnHost you set 1 to 6 players in the startup variables. The developer hasn't published an official maximum. We recommend our plans for 4, 4, 6 and 6 players. More players and bigger factories mean more RAM.

Can I upload my own save?

Yes. Upload the file via the file manager or SFTP to the AlchemyFactory/Saved/SaveGames folder and restart the server. If there's already a world in there, make a backup first.

What can I set in the startup variables?

Server name, server list visibility, server and admin password, the player count (1 to 6), the number of admins, autosave mode, pause when empty and automatic updates. You find them in the panel under Server → Settings → Startup variables. Ports, Steam Relay, LAN and the Steam connection retry are managed by RespawnHost. All changes take effect after a restart.

Alchemy Factory is only available for Windows PCs, so crossplay with consoles isn't a thing. Co-op runs through Steam.

Do Workshop blueprints work on the server?

The server itself can't load content from the Steam Workshop, and Workshop mods on the server aren't supported. Each player subscribes to blueprints in their own Steam client and uses them from there.

Do I need to update the server after a game update?

Yes, otherwise it rejects players with "invalid version". With us a restart is enough: the server checks for updates on start and installs them automatically.

Does the factory keep running when nobody is online?

No, as long as pause_when_empty is on (the default). The simulation then pauses as soon as the last player leaves, and the server saves. The server itself keeps running, though, and pay-per-use keeps billing. If you want to save money, stop it completely afterwards.

How much RAM does an Alchemy Factory server need?

In our test a fresh world used around 460 MB idling, measured without a compatibility layer. For four-player co-op 4 GB is enough, for growing factories we recommend 6 GB, 8 GB for 6 players and 12 GB for large factories with 6 players.

Do I need a second copy of the game for the server?

No. The server app can be downloaded anonymously via SteamCMD without owning the game. With us it's already installed anyway.

Why can't anyone join my server?

Usually it's a version mismatch after a patch. A restart pulls the current version on our side. Also check the server password and, if you join through the server list, whether server_public is set to 1. Right after starting, connecting to Steam can take a few attempts.

We create automatic backups of your saves. You can also make manual backups at any time and restore them in the panel with one click. That's worth doing before uploading a different save.

Do I get SFTP access?

Yes, full SFTP access to all server files, including ServerConfig.ini, saves and logs. ServerConfig.ini is rewritten from the startup variables on every start, so change settings there.

What happens when my credit runs out?

The server stops automatically. Saves, configuration and files are kept, only the progress since the last autosave is missing. Once you top up, you can start it again.

Is there a minimum term?

Not with pay-per-use. You top up credit and only pay for the time your server is running.

How fast is my server online?

The server itself is up in under 90 seconds. On the first start it still downloads the roughly 413 MB of game files, which takes a little longer depending on the location.

How do I reach support?

Via ticket and through our Discord, usually on weekends too.

Basics

What is an Alchemy Factory server?

An Alchemy Factory server is an always-reachable dedicated server for D5 Copperhead's automation game. Instead of one player hosting the world on their own PC, your factory runs on the server and everyone connects as a client: by IP, by join code or through the in-game server list. The official dedicated server has existed since the 1.0 release in September 2026, and the developer still labels it experimental. At RespawnHost you rent it pay-per-use from 0.0320 €/h or as a fixed plan from 8.00 €/month.

Frequently asked questions about Alchemy Factory servers

When you order, RespawnHost automatically generates a random admin password. You find it in the panel under Server → Settings → Startup variables and can change it there, then restart the server. In game, press Enter to open the chat and type /admin YourAdminPassword, /help shows the commands. max_admins sets how many admins there can be at once (1 by default). /setadmin doesn't work on dedicated servers.

Alchemy Factory Server Hosting: a Dedicated Server for Your Co-op

In Alchemy Factory you start with a small workshop and turn it into a factory where conveyor belts, pipes and magic do the work. Eventually you're making potions, jewellery and relics, fulfilling orders and running a shop with its own customers. Version 1.0 added a multiplayer lobby, join codes and an official dedicated server. With a server of your own, your shared factory no longer depends on one player's PC.

Why rent an Alchemy Factory server from RespawnHost?

In regular co-op, one player hosts the world. If they're offline, nobody else can get to the factory either. On a rented server the save lives in one central place, and anyone in the group can jump in whenever it suits them. The server app is small at around 413 MB, doesn't need a second copy of the game and runs on our side without any port forwarding on your router.

You set the ServerConfig.ini settings in the panel under Server → Settings → Startup variables instead of maintaining a text file by hand: server name, player count, passwords, autosave mode and more. On top of that you get automatic backups, DDoS protection and full SFTP access to saves and logs.

Updates: server and game have to match

After an Alchemy Factory patch, an outdated server rejects players with an "invalid version" message. On our side the server checks for a new version on every start and installs it. So after a game update, a restart is all it takes. If something still gets stuck, start with our guide to Alchemy Factory troubleshooting, then reach our support team via ticket and Discord.

What you get with your Alchemy Factory server

Our file manager guide shows how to upload files right in your browser. Changes to the startup variables take effect the next time the server restarts. Our setup guide explains every setting step by step.

Pay-per-use or fixed plan: which suits your factory?

Alchemy Factory pauses the simulation while nobody is connected. When no one is playing, nothing happens in the factory anyway. That's why pay-per-use fits the game well: you pay by the second, only while the server is running. A four-hour session on the entry plan with 4 GB costs around 0.13 €.

A paused server is still running and still costs money. So stop it after your gaming night, but only once everyone has left the game: by then it has saved automatically. If you want the server reachable around the clock, go for the fixed plan from 8.00 €/month, with term discounts of up to 20% for 360 days. Either way, you pay from credit you top up in advance.

Choose between Germany (EU), Salt Lake City, UT (US West), Charlotte, NC (US East), and Noida (India). Compare locations with the ping test and consider where your fellow players are based.

Host it yourself or rent an Alchemy Factory server?

There are three ways to run a shared factory, and they differ quite a bit in practice:

Co-op from inside the game: one player opens a lobby, the others join. It costs nothing extra, but the world only exists while the host is playing.

Dedicated server on your own PC: the server app (Steam app 4550060) can be downloaded anonymously via SteamCMD, but only as a Windows build. You need a machine that stays on, port forwarding for UDP 9877 and 9878, and you have to update it yourself after every patch.

Rented server at RespawnHost: the same official server app, ready to go, with auto-update on start, backups and all settings in the panel's startup variables. Since the developer only ships a Windows version, we run the server on Linux through a Windows compatibility layer. D5 Copperhead also labels the server experimental: connecting to Steam sometimes takes several attempts, and the server then retries on its own.

How do I configure an Alchemy Factory server?

The settings live in the ServerConfig.ini file in the server's root folder, section [ServerSettings]. At RespawnHost you set them in the panel under Server → Settings → Startup variables. The server writes them to ServerConfig.ini on every start, so direct changes to the file via SFTP get overwritten. These are the available values:

Important: the server does not save when it shuts down. Everything since the last autosave is lost on a stop or restart. Keep the autosave mode at 1 (every 5 minutes) and ideally stop the server only once everyone has left the game. With pause_when_empty it saves at exactly that moment.

Becoming admin: when you order, RespawnHost automatically generates a random admin password. You find it in the startup variables and can change it there. Press Enter in game to open the chat and type /admin YourAdminPassword. /help lists the available commands. The developer has disabled /setadmin on dedicated servers, so the admin password is the way to get admin rights. Alchemy Factory offers no RCON or REST interface.

In our test without a compatibility layer, the server used around 460 MB of RAM idling on a fresh world. On Linux there's some overhead on top, and large late-game factories need more. For getting started with four players, the 4 GB plan (8.00 €/month) is enough. As the factory grows, move up to 6 GB, for 6 players we recommend 8 GB and for large factories with 6 players 12 GB (21.60 €/month). More than 6 players aren't possible with us.

server_name: the name in the server list (startup variable "Server name")
max_clients: the player count, 4 by default in the game, 6 by default with us and adjustable from 1 to 6 (startup variable "Max players")
server_public: at 1 (default) the server shows up in the server list and multiplayer lobby, at 0 it doesn't (startup variable "Show in server list")
server_password and admin_password: join password (empty by default) and password for admin rights (startup variables "Server password" and "Admin password")
max_admins: how many players can be admin at the same time, 1 by default (startup variable "Max admins")
autosave_mode: 0 saves when sleeping, 1 every 5 minutes (default), 2 every 10 minutes, 3 never (startup variable "Autosave mode")
pause_when_empty: at 1 (default) the simulation pauses without players, and the game saves when the last player leaves (startup variable "Pause when empty")
session_retry_seconds: after how many seconds the server retries a failed connection attempt, fixed at 10 with us
server_port and query_port: UDP 9877 and 9878 in the original. With us the panel assigns the ports, and Steam Relay (server_relay) and LAN are off so direct joining by IP works. RespawnHost manages these values

Alchemy Factory 1.0: what the release means for servers

After its Early Access phase, Alchemy Factory reached version 1.0 in early September 2026. New additions include drinks from the Brew Barrel, cart logistics where you turn into a cart yourself and ride on rails, and recognitions for your shop. More important for groups: 1.0 brought the multiplayer lobby, join codes and the experimental dedicated server.

Online and LAN co-op run through Steam, and the game is Windows only. The server can't download blueprints from the Steam Workshop on its own. Each player subscribes to them in their own Steam client and uses them from there.
