We present the results of a search for on-axis optical afterglows using the Zwicky Transient Facility (ZTF). Our search yielded seven optical transients that resemble on-axis LGRB afterglows in terms of their red colors (g - r > 0 mag), faint host galaxies (r > 23 mag), rapid fading (dr/dt > 1 mag day-1), and in some cases X-ray and radio emission.
