The Argentine's exit was confirmed on Friday with speculation linking Alfaro as a potential successor to Daniel Garnero as Paraguay boss.
"We thank Mr Gustavo and his team for their dedication during their time leading the Costa Rica team," the Costa Rican Football Federation (FCRF) said in a short statement.
"At FCRF we will continue to build the path towards the 2026 World Cup. We will keep our fans informed and we reiterate our commitment to continue working for the development and success of national football."
The 61-year-old, who took charge of Ecuador at the 2022 World Cup, guided Costa Rice to the Copa America this year as his side were eliminated in the group stage by finishing third.
