The field in numbers

The open BCI field, week 40.

Prepared for a sample subscriberData 3 October 2026Checked by a Radar analyst

120projects on the map, of 3,326 read

What moved, in four lines

The field is alive, and it is mostly acquisition.113 of 120 projects changed in the last month. 56 of 120 are hardware and acquisition; real-time and embedded is the thinnest layer, with one project.
Interoperability is still the exception.30 of 120 projects declare a standard. MNE/FIF (10), BIDS (7) and LSL (7) lead; 101 links connect the projects that share one.
Consumer neural input is drawing outside developers.Community controls for Meta's neural wristband gained 13 stars in a week around a 1 October release, with a single maintainer.
The newcomers are research code.Of 6 new projects, 3 are in scope, 2 adjacent and 1 a concept. None is yet a product; two are worth a second look in a quarter.

Movers, and the newcomers, reviewed

Who gained this week.

Stars gained in seven days, with what stands behind them
Project	Stars	7 days	BRS	Profile	Contributors	Latest release
`brainflow-dev/brainflow`Acquisition library across EEG, EMG and ECG devices	1,770	+9	90	87	69	5.23.026 Sep
`mne-tools/mne-python`The reference MEG and EEG analysis stack	3,536	+8	72	100	471	v1.13.211 Sep
`neuropsychology/NeuroKit`Physiological signal processing in Python	2,377	+11	49	75	106	v0.2.132 Mar
`callbacked/kinesis`Controls for Meta's neural wristband, on macOS	108	+13	40	42	1	v0.5.01 Oct

Analyst note. The week's largest gain on the map, BasedHardware/omi (+48), reached it through a bci topic. It reads as an AI wearable rather than a neural-signal project, so it is kept out of the movers; a subscriber who tracks consumer wearables would see it in their own edition.

New entrants, checked one by one

Project	BRS	Language	Verdict
`OS-EEG-COLLECT/eeg-collect`An application for simplified EEG data collection.	94	Vue	In scope

`igor688-hub/neurodiagnosis-eeg`PTSD detection from one minute of six-channel dry EEG.	40	Jupyter Notebook	In scope
`Elnazkarami/N-DOS`Animal neuroscience data, recovered and queried; useful to labs, not a BCI.	63	Python	Adjacent
`kladkogex/20-watt-computer`A free textbook on how the brain computes. Education, not software.	61	TeX	Adjacent

The stack, and the risks in it

What the field is standardising on.

FIF/MNE10
BIDS7
LSL7
BrainFlow4
NWB4
EEGLAB2
FieldTrip2
OpenBCI2
EDF1

Read. The MNE file format and BIDS organise data; LSL and BrainFlow move it from devices to software, so a device that speaks both is usable by every project here that declares either. None of the declared standards covers timing or consent.

Reach without momentum

Project	Stars	Days quiet	What it means
`vlawhern/arl-eegmodels`Reference implementations of EEG models such as EEGNet	1,565	1,614	Pin it, or own a fork: it will not change under you, and it will not be fixed for you.
`wzpan/wukong-robot`Voice assistant that lists brain–computer input	7,127	707	Large audience, no recent work: reach is not momentum.

Kept out by review

SUSE/BCI-dockerfile-generator — here “BCI” means SUSE's Base Container Images.Excluded
lebidan/sbnd — “neural decoders” for error-correcting codes, not for neural signals.Excluded
scouter-project/scouter — an application-performance monitor with 2,178 stars; its bci topic is not about brains.Excluded

All three reached the public map on 3 October through their keywords. None appears in a subscriber's brief, and since 16.10.1 all three are on the map's exclusion list in data/seeds.json. Source: data/radar.json, standards_graph and projects, 2026-10-03.
