Bernstein

Cursor

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 Bernstein and Cursor.

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
