All 16 alternatives →+ Code-as-action agents in about a thousand lines of core code that work with any Hub model.
− Running model-written Python needs sandboxing, which is left mostly to you.
+ Unified provider interface and React hooks make streaming chat UIs trivial.
− Major-version upgrades have required significant rewrites.
+ MCP-first design means any MCP server becomes a Goose capability with no glue code.
− Less tuned for coding than Claude Code, so results vary widely by model.
+ Explicit state graphs with checkpointing make long-running agents debuggable and resumable.
− Steep learning curve and more boilerplate than simpler agent SDKs.
+ Largest integration catalogue of any framework, so almost any provider is one import away.
− Frequent breaking API changes and heavy abstractions make simple things feel over-engineered.
