Built for performance
Rust simulation, WebGPU renderer, compact binary netcode. Late-game fights with hundreds of cells on screen stay smooth, even on modest hardware.
Gamemode creator
Tune world size, split rules, merge timers, viruses, teams and win conditions in the visual editor, then publish a live server anyone can join.
Map editor
Place walls and pellet zones with snap and symmetry tools, start from a template, and watch the map update live as you draw.
Instant replay clips
Press F9 and the last 60 seconds are saved as a clip. Rewatch with scrubbing and slow motion in your library, then publish the keepers to your profile.
XP & leveling
Every match earns XP. Climb 100 levels on a curve that keeps early ranks fast, and show your tier icon on the leaderboard as you rise.
Public profiles
Your page collects your stats, created gamemodes, trial times and published clips, with your best play pinned on top.
Friends & parties
See which friends are online and join their game in one click. Party up to queue 4v4 team modes together, or play private rooms with your group.
Multiboxing
Drive a second cell from the same account and switch between them on the fly, no second browser needed. Pull off splitruns solo in modes that allow it.
Host custom games
Spin up your own room for any gamemode, public or invite-only, with host controls over the match. Share the invite link and friends drop straight in.
Time trials
A first for agar-style games: server-timed solo courses. Thread mazes, slip past patrol viruses and race the clock, then put your best run on the leaderboard. A handful of courses are live today, with more on the way.
Race the trialsWhat is alis.io?
alis.io is a free agar.io style multiplayer game you play in your browser. Start as a tiny cell, eat pellets and smaller players to grow, split to hunt or escape, and try to reach the top of the board. There is nothing to download and no sign-up needed to play.
What sets alis.io apart is that players make the content. A visual editor lets anyone build custom gamemodes and maps and publish them as free hosted private servers with an invite link, and features like macros, multibox, free zoom and instant replays are built into the game rather than added by mods.
- Is alis.io free?
- Yes. Playing, hosting a private server and publishing your own gamemode are all free. Optional cosmetics are bought with coins earned by playing, never with real money.
- Do I need to download anything?
- No. alis.io runs entirely in your browser on desktop and mobile. There is no client, launcher or extension to install.
- Can I play with friends?
- Yes. Host a public or invite-only room in one click and share the link. Friends drop straight in from any browser, no account required.
- Is alis.io the same as agar.io?
- alis.io is an independent game inspired by agar.io, not operated by or affiliated with Miniclip. It keeps the classic cell-eating loop and adds private servers, custom gamemodes and a map editor on top.
