pensyve vs initrunner
pensyve: Pensyve is a universal memory runtime for AI agents that eliminates amnesia across sessions. It offers three memory types (episodic, semantic, procedural), 8-signal fusion retrieval, and FSRS-based forgetting curve. Framework-agnostic with SDKs for Python, TypeScript, Go, and integrations with LangChain, CrewAI, AutoGen, plus native plugins for Claude Code, Cursor, and VS Code.; initrunner: InitRunner lets you define an agent in one YAML file, chat with it, run it autonomously, and deploy it as a daemon triggered by cron, file changes, webhooks, or Telegram messages. It supports multiple execution modes, built-in memory, cost controls, multi-agent orchestration, and security features. Built on PydanticAI.

TL;DR
Choose pensyve if…Persist agent knowledge across sessions and avoid repetitive questions
Choose initrunner if…Automated code review: set up a daemon that reviews pull requests or file changes.
