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 coordination). A built-in janitor runs tests, linting, and type checks on every agent's work before it merges. Supports 18+ CLI agents including Claude Code, Codex, Gemini CLI, and Aider. Apache 2.0 licensed.

Questions & Answers

As answered by people managing Bernstein and EverDev.

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

    Finally, parallel agents that actually work

    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 don't step on each other. The janitor verifies tests pass
    before anything merges. What impressed me most: zero LLM tokens wasted on coordination โ€” the scheduler is pure Python. Went from running one agent at a time to having 5 working simultaneously on different tasks. The TUI dashboard is a nice touch for monitoring what's
    happening in real time.

    ๐Ÿ Competitors: agor, fastn.ai, Phinite AI, TeamHero
    ๐Ÿ‘ Pros:    Parallel agents in isolated git worktrees โ€” no merge conflicts during work|Deterministic python scheduler, no llm overhead on coordination|Supports multiple cli agents (claude code, codex, gemini cli)|Built-in test verification before merge|Easy setup โ€” pip install bernstein and one command to start
    ๐Ÿ‘Ž Cons:    Python 3.12+ required, won't work on older setups|Documentation could be more beginner-friendly

  • Orchestration primitive or desktop ADE? Choosing your multi-agent coding layer in 2026
    Orchestration primitives. A library or CLI you import into your own workflow. You don't see a window; you see a process you can pipe into other things. Examples: Bernstein (the project this blog belongs to โ€” 18 CLI adapters, Python-importable), Workz, certain configurations of Plandex. LangGraph and CrewAI are adjacent but different โ€” they orchestrate LLM calls, not CLI coding agents. - Source: dev.to / 4 months ago
