Third-party API sandboxes are flaky, incomplete, and drift from production without warning. pikopod is an open-source Go CLI that simulates API sandboxes locally and detects drift, flagging when a real API stops matching what your integration expects, before users hit errors. Mocking tools fake responses; pikopod also checks them against the real API. Built from years of maintaining payment integrations. Apache-2.0, installable via Homebrew.
