evolver vs Acontext

evolver: Evolver scans an agent's logs and memory, selects a matching Gene or Capsule from a local asset store, and emits a protocol-bound GEP prompt for the next improvement step. Each run records an auditable EvolutionEvent, and hooks wire it into Cursor, Claude Code, Codex and other runtimes.; Acontext: Acontext is a Context Data Platform designed to help build scalable cloud-native AI agents by managing context storage, retrieval, and state. It solves common problems like inefficient LLM message storage, complex long-running agent management, and lack of agent observability and learning capabilities.
