Valheim server analytics, for your longhouse.

The BepInEx mod reads server FPS, sessions and playtime, bosses beaten and world objects. It also loads on crossplay servers. If your host blocks BepInEx, basic mode checks a public server's query port for status, ping and version; crossplay player count may be unknown.

See who plays together, how far the group has progressed, and when a growing world starts costing server FPS.

What ServerStats tracks on Valheim servers

A server-side BepInEx 5 plugin. Players need no mod, and it runs on crossplay servers too.

Performance

Server FPS (30 a second) and frame work time
Frames over 50, 100 and 250 ms
Lag spikes split by stage: world-object sync, zones, network, world save, physics
World objects (ZDOs) and ZDO traffic, world save time

Players

Sessions by platform, Steam or Xbox
Ping from Valheim's own heartbeat
New and returning players, retention for public servers

Progress

Bosses beaten, with how many players were nearby and whether it was the first kill
Raids by event and biome
Deaths by biome
Portals by type, world day

Moderation (opt-in)

Kick, timed ban and unban, mute, messages, from the dashboard
Store revenue matched to players, if you run a public server with a store (Operator)

No install yet? Basic mode reads A2S on 2457 (game port + 1) and needs -public 1. On crossplay servers the info reply may say 0 while occupied; a positive anonymous player-list count is used if available, otherwise player count stays unknown. Check any Valheim server with the Valheim server status checker.

Plugin-specific payment and gamemode integrations for Valheim are planned. The general dashboard and payments log work today.

The number that matters: server FPS and world objects

33ms

One frame at 30 a second

Target: 30 fps
Lag spike: 100 ms (configurable)
Possible contributor: World-object sync
Also measured: ZDOs and traffic

The Valheim dedicated server has no fixed tick: it runs Unity frames capped at 30 a second, so each frame has 33 ms. ServerStats measures the work in each frame and leaves the wait out.

Every placed piece, item and creature can add world objects the server tracks and sends. ServerStats counts ZDOs and their traffic, and splits measured frame work by stage so you can see whether sync, zone work or a world save coincides with a spike. A high ZDO count alone does not establish the cause.

BepInEx keeps no per-plugin timings, so another plugin's work shows up as other updates, not by name.

One mod. About five minutes.

Valheim questions

Does it work on crossplay servers?

The server-side mod loaded in our -crossplay test; players need no mod. If your host blocks BepInEx, basic mode can check the public query port (-public 1), but the crossplay player count may be unknown.

Why is my Valheim server lagging?

Several stages can lengthen a frame, including world-object sync, zones and saves. ServerStats shows ZDO count and traffic beside frame time and measures the work in each stage; use that timing to investigate, rather than ZDO count alone.

Do players need the mod?

No. It runs only on the server.

How do I claim it without console access?

As an admin in game, open the F5 console and run kick serverstats:claim:SS-XXXX-XXXX-XXXX. The plugin answers it and never kicks anyone.

Is it worth it for a small group?

Free covers one server forever, which is most Valheim groups.

Is it free?

Free covers one server with 24 hours of history, forever, with no card. Operator is $9.99 a month for 10 servers and 90 days of history, which you need for week-on-week trends and D7 or D30 retention. Yearly billing gives two months free.
