agentscope-java vs harness-sdk

Q: Which is better, agentscope-java or harness-sdk?

By GitHub stars, harness-sdk has more community adoption, but the best choice depends on your specific use case.

agentscope-java: AgentScope Java 2.0 is a framework for building distributed, long-running agents on the JVM, with a typed event stream, tool permission gating, middleware and sandboxed workspaces. It supports subagent orchestration and distributed session and memory storage with cross-replica recovery.; harness-sdk: This monorepo holds the Strands Agents SDKs for Python and TypeScript plus Strands harness, a fully assembled agent created with one create_harness() call. It runs in your own process and covers the agent loop, tools, MCP, multi-agent patterns, memory, sessions, guardrails, tracing and evals across Bedrock, Anthropic, OpenAI, Gemini and other providers.
