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.

Could you build this?
Partial A basic CLI proxy is vibe-codeable, but accurately simulating API drift, detecting structural and behavioral schema breaking changes, and recording/replaying complex stateful APIs requires deep API protocol and testing expertise.
What it would actually take: Built in Go, it requires an HTTP reverse proxy engine, dynamic OpenAPI/JSON-Schema validation, and statistical drift detection on live vs mocked payloads. The challenge is inferring stateful transitions (e.g., entity lifecycles) and parsing ambiguous edge-case API responses without generating excessive false positives. It requires strong backend systems and developer-tooling engineering.
