# ArmaDB

> Public database of Arma Reforger servers, Workshop mods and scenarios.
> Measured first-hand from the game's own systems and from the servers themselves,
> never copied from other Arma sites.

Last updated: 15 October 2026. Servers tracked: 61619. Mods indexed: 27548.
Scenarios: 5905.

## What makes this source useful

- Every server, mod and scenario has its own permanent page with historical charts.
- Player counts are sampled continuously and rolled up hourly and daily; raw samples
  are kept 90 days, aggregates indefinitely.
- Mod data includes ratings, subscribers, downloads, versions and dependency graphs.
- Player counts are cross-checked against a second, independent measurement, so a server
  that overstates its population can be identified.
- Restarts are detected and kept as uptime sessions: for any server you can tell when it
  last restarted and how long each run lasted.
- Every change to a server's mod list (added, removed, updated) is recorded with a
  timestamp, on both sides: per server and per mod.
- National communities: the game protocol has no country field, but many servers state it
  in their own name ([ITA], [GER], [BRASIL]). Those are grouped per country; servers that
  do not say are left unassigned rather than guessed from their datacenter.

## Data

The JSON API needs a free API key (`X-Api-Key` header): sign up, generate one, done.
See [the API documentation](/api).

- [Servers API](/api/v1/servers): filter by region, mod, scenario, version, player count.
- Per server: [history](/api/v1/servers/{id}/history), [uptime sessions](/api/v1/servers/{id}/sessions),
  [mod changelog](/api/v1/servers/{id}/mod-changes).
- [Mods API](/api/v1/mods): usage across servers, ratings, tags, plus
  [adoption](/api/v1/mods/{id}/adoption): who added or dropped a mod recently.
- [Scenarios API](/api/v1/scenarios): every scenario with players and servers, per-region detail
  and daily usage.
- [Communities API](/api/v1/communities): servers and players per declared country;
  one country at `/api/v1/communities/{code}`.
- [Aggregate stats](/api/v1/stats), [history](/api/v1/stats/history),
  [breakdown](/api/v1/stats/breakdown) by region, ping site, host type, version and platform,
  and [uptime](/api/v1/stats/uptime): restarts and the servers up the longest.
- [Search](/api/v1/search?q=) across servers, mods and scenarios; [compare](/api/v1/tools/compare?a=&b=)
  two servers mod by mod.
