ak‑fetch is a production‑grade HTTP client/library (with a CLI wrapper) geared toward bulk data operations such as bulk API imports, large file uploads, and streaming massive datasets. It offers features like connection pooling, concurrent batching, exponential‑backoff retries, cookie‑jar session handling, real‑time progress monitoring and built‑in presets for services like Mixpanel, making it ideal for developers who need fast, memory‑efficient, and reliably‑retryable HTTP bulk‑request pipelines.
