Bernstein

No description of StackHive yet.

Bernstein is an open-source alternative to commercial agent platforms. It orchestrates multiple AI coding agents working on the same repo in parallel - each isolated in its own git worktree so they never step on each other. The scheduler is pure deterministic Python (zero LLM tokens spent on...

Questions & Answers

As answered by people managing StackHive and Bernstein.

What makes your product unique?

Bernstein's answer:

Bernstein is the only orchestrator that uses deterministic code for scheduling instead of an LLM. Every other multi-agent framework (CrewAI, AutoGen, LangGraph) burns tokens deciding what to assign where. Bernstein spends zero tokens on coordination - the Python scheduler makes auditable, reproducible decisions. It also isolates every agent in its own git worktree, so agents never stomp on each other's files.

Why should a person choose your product over its competitors?

Bernstein's answer:

  • No SDK to learn — works with CLI agents you already have (Claude Code, Codex, Gemini CLI)
  • No vendor lock-in — mix models in the same run
  • Verified output — janitor checks tests, lint, and types before merging
  • Cost savings — contextual bandit router cuts costs ~23% by learning which cheap model handles which task type
  • Reproducible — same inputs produce same scheduling decisions

How would you describe the primary audience of your product?

Bernstein's answer:

  • Solo devs who want to run 6+ agents in parallel on a 10-ticket backlog
  • Tech leads evaluating multi-agent workflows without committing to a vendor
  • Teams that already use AI coding agents daily and want to parallelize their workflow

What's the story behind your product?

Bernstein's answer:

Named after Leonard Bernstein, the conductor. The idea came from trying to coordinate three AI coding agents on the same codebase and watching them destroy each other's work. The first version used an LLM to schedule the other LLMs - it was slow, expensive, and hallucinated priorities. Replacing it with deterministic Python was the breakthrough.

Which are the primary technologies used for building your product?

Bernstein's answer:

  • Python 3.12+ with asyncio
  • Git worktrees for agent isolation
  • LinUCB contextual bandits for model routing
  • Textual for the TUI dashboard
  • Hatchling for packaging

Who are some of the biggest customers of your product?

Bernstein's answer:

  • Individual developers using it for personal projects
  • Open-source maintainers orchestrating codebase-wide refactors
  • Early-stage startups using it for overnight CI-fix automation

    I set up Bernstein on a mid-size Python project to see if multi-agent orchestration lives up to the hype. It does. One command, multiple Claude Code agents running in parallel, each in its own git worktree so they...
