The most simple case how to use standalone mode.

    from brian2 import *
    set_device('cpp_standalone')  # ← only difference to "normal" simulation

    tau = 10*ms
    eqs = '''
    dv/dt = (1-v)/tau : 1
    '''
    G = NeuronGroup(10, eqs, method='exact')
    G.v = 'rand()'
    mon = StateMonitor(G, 'v', record=True)
    run(100*ms)

    plt.plot(mon.t/ms, mon.v.T)
    plt.gca().set(xlabel='t (ms)', ylabel='v')
    plt.show()
