Python SDK Beta: How the Language of AI Runs Faster and Safer with Fastly

Fastly launched the Compute Python SDK beta in June 2026, allowing developers to run Python applications on its edge network using cross-compiled standard CPython in WebAssembly sandboxes. The solution combines memory snapshotting for microsecond startup speeds with ephemeral sandbox isolation for enhanced security against untrusted code execution, including LLM-generated workflows. Current limitations include unavailable native ML frameworks (NumPy, SciPy, Pandas) and no filesystem or threading support, with Fastly inviting community feedback via GitHub toward general availability.
