bernstein vs initrunner
bernstein: Bernstein is a deterministic orchestrator for AI coding agents. It decomposes a goal into tasks, spawns agents in parallel on isolated branches, verifies results with quality gates, and merges only passing code. It supports 31+ agent adapters and can run on any model or provider.; 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 bernstein if…Speed up feature development by dividing complex tasks among multiple AI agents
Choose initrunner if…Automated code review: set up a daemon that reviews pull requests or file changes.
