alis.io vs Sigmally: an honest comparison
Updated July 2026
Full disclosure: alis.io is our own game, so you are reading a comparison written by one of the two sides. We keep it honest anyway, because a comparison that pretends the other server has no strengths is useless to you and obvious to everyone.
What Sigmally is
Sigmally is the agar.io private server you will see most often in search results in 2026, and for good reason: it is classic agar gameplay in the browser, free, with skins, events and a large Discord community around it. If you want drop-in classic agar with an active player base, it delivers exactly that.
What it is not is a platform. You play the game Sigmally runs, the way it runs it: there is no making your own gamemode and no hosting your own room with its own link.
What alis.io is
alis.io is an agar platform rather than a single arena. Official servers cover classic FFA plus physics variants like instant merge and self feed and objective modes like team deathmatch and a daily tower climb. Every mode is a free hosted server, playable as a guest in the browser.
The platform half: a visual editor to build your own gamemode and map and publish it to its own hosted server, one-click public or invite-only rooms with shareable links, game servers in five regions (Europe, Miami, Mexico City, São Paulo, Singapore), and built-in feed macros, replays and style options so nothing needs an extension.
Where Sigmally is the better pick
- You want classic agar with the biggest crowd in it. Sigmally has the established community, and in a game about eating other players, population is a real feature.
- You care about the skins and events scene that has grown around it.
- You want the server everyone in your Discord already plays.
Where alis.io is the better pick
- You want more than one ruleset: instant merge, self feed, 250-cell splits, team objectives and a daily climb, each on its own server.
- You want to host a room, public or invite-only, and drop a link your friends can click into from any browser.
- You want to build a gamemode or map yourself and see it live on its own server page, no coding.
- You play far from Europe or North America: five regions with automatic lowest-ping selection.
- You want macros, replays and cosmetics built in rather than installed as extensions.
The honest bottom line
These are both free browser games and there is no lock-in, so the real answer is to play both. Sigmally is the stronger pick for pure classic agar with a big population; alis.io is the stronger pick the moment you want to change the rules, host the room yourself, or play a mode nobody has made yet.
