Prefer this fork only if you need its custom repo/workflow shape or must stay on its older baseline. If you want current OkHttp behavior, active maintenance, and the full upstream feature set, upstream is the safer choice.

Prefer this fork only if you are maintaining a legacy Java 1.6 or old Android application and need the fork-specific compatibility behavior. For new or actively maintained systems, upstream OkHttp is the better choice by a wide margin.

Prefer upstream unless you specifically need this frozen baseline; the fork adds no visible value and is already behind on fixes.

Prefer this fork only if you need its legacy behavior or custom internals and are willing to own the maintenance burden. For new work, upstream OkHttp is the better default because it is active and far more complete.

Prefer upstream unless you specifically need this older, divergent fork for legacy compatibility or to preserve its backported fixes. For new work, the fork’s age and drift make it a poor default choice.

Choose this fork only for legacy compatibility. If you can adopt modern OkHttp, upstream is the better default by a wide margin.

Choose upstream unless you specifically need the fork’s multiplatform/experimental HTTP/3 direction and are prepared to maintain a large diverged codebase. For general OkHttp adoption, this fork is too stale and too far from upstream to be the safer default.

Choose this fork only if you specifically need its legacy compatibility and backported fixes. For most adopters, upstream OkHttp is the safer choice because this fork is stale and materially behind current capabilities.

Prefer upstream unless you must keep a legacy 2017 OkHttp baseline or depend on the fork's early API/behavior changes; this fork is too stale for new adopters.
