ContextStream is built around one memory that follows you between claude code, cursor, codex, cline and windsurf over mcp, while DeepSeek Harness focuses on everything is a plugin: models, tools, skills, sessions, sandboxes, storage, loops, scheduling and the ui are all swappable in configuration. The key question is whether you need agentic capabilities that autonomously handle multi-step tasks, or inline completions that keep you in flow as you type.
