Rat Lab Discord: Where the Invite Link Is Listed and How to Join the Server
See where fan-run hubs list the Rat Lab Discord link, how to join through the Discord app, and how to tell official channels from scam DMs. No specific invite URL can be confirmed as current and official.
Quick answer
The Rat Lab Wiki (ratlab.top) lists an 'Official Discord' item next to 'Play on Roblox' in its site links, and the fan codes hub (ratlab.wiki) sends readers to its Official Links page — hubs describe the server as a place for player discussions, squad-ups for escapes, update pings, and code announcements. No invite URL can be confirmed as current and official, so take the link from a hub's own link section, join through the Discord app, and check the server against the Evil Science Rat Lab game before trusting it.
- Server role: "Join player discussions, squad up for escapes, and get update pings."
- Companion news source: the Evil Science developer group on Roblox for news and patch notes.
- Announcement venue: Discord announcements — patch notes, like goals, and weekend events — often carry one-time codes.
Where the Rat Lab Discord invite is listed
No invite URL, exact server name, or server ID can be confirmed as the current official one. What is established is where the link is surfaced: the Rat Lab Wiki (ratlab.top) lists an 'Official Discord' item in its site links next to 'Play on Roblox', and ratlab.wiki sends readers to 'the Discord howto on the Official Links page'. Both are player-run properties — ratlab.top describes itself as a 'Non-official fan wiki' and states it is 'Not affiliated with Evil Science or Roblox' — so their 'official' label is secondhand attribution, not developer confirmation. Treat any invite found through these hubs as unconfirmed until the server's identity is checked against the Evil Science Rat Lab game. These hub details are current as of September 20, 2026 — recheck the invite at the hub before joining.
How to join a Discord server with an invite link

Telling official Rat Lab Discord channels from scam DMs
The fan codes hub's scam checklist for code offers circulating around the Discord doubles as channel-verification guidance for anything received in or around the server.
Tips
Check the channel
Check that the information comes from an official channel, not a random Discord DM.
Real promos are free
Never buy 'private codes' from strangers in chat — real promos are free and public.
Refuse verifiers
Walk away if asked to enter a password, a Robux gift card, or a 'verifier' site.
Know what is not a promo code
Mutation Index colours or the paid All Mutation Codes gamepass being sold as 'secret promo codes' is a red flag — they are not promo codes.
