Although chimichurri and pesto are both made with a base of fresh herbs, they are not the same sauce. Aside from originating in separate countries (pesto is Italian!), chimichurri does not traditionally contain any fresh basil, whereas pesto is typically made primarily with basil. Pesto is also usually pulsed finely in a food processor whereas authentic chimichurri sauce has a chunky texture and is made with chopped herbs.
