 +With the arrival of LOw Frequency ARray (LOFAR) and the Murchison Widefield Array (MWA), sensitive widefield radio telescopes, we have been making rapid progress towards constraining the transient population at low radio frequencies. The transients teams utilise two key strategies: blind searches and triggered follow-up of transients detected by other facilities.
 +First, I will outline the current developments in blind searches including the discovery of the first transient source at low-frequencies by LOFAR, the deepest survey to date with MWA and the current status of an all observable sky radio transients facility using LOFAR (AARTFAAC). These results are facilitated by the publicly available LOFAR transients pipeline, an automated transient detection pipeline developed by the Universities of Amsterdam and Oxford.
 +In the second part of this talk, I will give the highlights of our triggered transient searches using MWA and LOFAR, including triggering on gamma-ray bursts and the recent gravitational wave source GW150914. We will then look towards the future capabilities of LOFAR as a fully automated, responsive telescope.
