About serena #
Serena's agent-first tool design involves robust high-level abstractions, distinguishing it from approaches that rely on low-level concepts like line numbers or primitive search patterns.
Practically, this means that your agent operates faster, more efficiently and more reliably, especially in larger and more complex codebases.
While it is humans who download and set up Serena, our end users are essentially AI agents. As the ones actually applying Serena's tools, they are in the best position to evaluate Serena.
serena is listed in this index written primarily in Python, with 31k stars on GitHub. Its latest recorded repository push was in October 2026; that is not an ASE editorial review date.
