A player made and maintained cheat detection tool for osu!. Provides support for detecting replay stealing, remodding, relax, and aim correction from a profile, map, or set of osr files.
Project description
Circlecore
Circlecore is a both a cheat detection library and a utilities library for osu!. Features include:
- Replay Stealing / Remodding detection
- Unstable Rate (ur) calculation, for relax cheats
- Finding suspicious movements in replays (called Snaps), for aim correction cheats
- Frametime analysis, for timewarp cheats
Built for use in Circleguard, circlecore is easily integratable into any existing python project and we have worked hard to ensure it is easy to use. See Usage (and our documentation at https://circleguard.dev/docs/circlecore) for developer guidance.
Circleguard is developed and maintained by:
Installation
Circlecore can be installed from pip:
pip install circleguard
This documentation refers to the project as circlecore to differentiate it from our organization Circleguard and the gui application Circleguard. However, circlecore is installed from pypi with the name circleguard, and is imported as such in python (import circleguard).

Usage
We have documentation and a tutorial at https://circleguard.dev/docs/circlecore. However, below is a quickstart guide.
# replace "key" with your api key
cg = Circleguard("key")
# replays by http://osu.ppy.sh/u/2757689 and http://osu.ppy.sh/u/4196808 on map
# http://osu.ppy.sh/b/221777
r1 = ReplayMap(221777, 2757689)
r2 = ReplayMap(221777, 4196808)
for result in cg.steal_check([r1, r2]): # r is a StealResult
r = result
print(f"{r.replay1.username} +{r.replay1.mods} vs {r.replay2.username} "
f"+{r.replay2.mods} on {r.replay1.map_id}. {r.similarity} sim")
for result in cg.relax_check(r1): # r is a RelaxResult
print(f"{r1}, {result.ur:.2f} ur")
for result in cg.correction_check(r2): # r is a CorrectionResult
snap_times = [snap.time for snap in result.snaps]
print(f"Number of snaps: {len(result.snaps)}, times: {snap_times}")
# ReplayMap isn't the only way to represent replays; we can also get a user's
# top 10 plays:
u = User(12092800, span="1-1")
# or a local replay:
r3 = ReplayPath("/path/to/local/osr/replay.osr")
# or all of a user's replays on a map:
mu = MapUser(221777, 2757689)
# and more...you can find them all at
# https://docs.circleguard.dev/en/v4.3.4/appendix.html#circleguard.loadable.Loadable.
# all of these can be investigated in the same way as ReplayMaps above, eg:
r = cg.steal_check([r, r3, mu])
# or just one:
r = cg.relax_check(u)
# there are more checks than just the above, as well - you can find them all at
# https://docs.circleguard.dev/en/v4.3.4/appendix.html#circleguard.circleguard.Circleguard
from circleguard import *
cg = Circleguard("key")
m = Map(221777, span="1-2") # First two replays on 221777
# all Loadables (that is, anything that can be loaded - Map, User, ReplayMap,
# ReplayPath, etc) defer loading anything from the api until necessary.
# We can force the Map to load information about its replays:
cg.load_info(m)
# Once info loaded, we can iterate over Map, User, and MapUser to get the
# replays contained by them. Formally, these objects are called "LoadableContainers"
for replay in m:
print(f"{replay.username} +{replay.mods} on map {replay.map_id}")
# the map is info loaded, but not yet loaded, so its replays are not yet loaded either
print(m[0].loaded) # False
print(m[0].replay_data) # None, unloaded replays don't yet have replay data
# we can force load m, which will load its replays:
cg.load(m)
print(len(m[0].replay_data)) # 11100
# all this loading is only necessary if you want to handle Loadables specially
# before checking them - cg.steal_check (and the other methods like cg.relax_check)
# automatically load the Loadables passed to them, which is why we didn't need
# to force load anything ourselves in the first example.
