Bernstein

No description of Claude Usage 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...

Features and specs

What each product offers, as listed by its team.

Claude Usage 5 features
Bernstein 17 features
  • Cost Tracking Visibility
    Claude Code Usage provides clear visibility into how much you're spending on Claude API usage, helping users monitor and manage their costs effectively. It breaks down costs by model and gives both daily and monthly summaries.
  • Simple CLI Tool
    The tool is a lightweight command-line utility that is easy to install via npm and simple to use with straightforward commands like 'claudecodeusage' to get immediate cost insights without complex setup.
  • Multi-Model Breakdown
    It provides a detailed breakdown of token usage and costs across different Claude models (e.g., Opus, Sonnet, Haiku), allowing users to understand which models are consuming the most resources and optimize accordingly.
  • Daily and Monthly Aggregation
    The tool aggregates usage data at both daily and monthly levels, giving users flexibility to analyze their spending patterns over different time periods and identify trends or anomalies.
  • Open Source and Lightweight
    Being open source on GitHub, the tool is transparent, free to use, and community-driven. Users can inspect the code, contribute improvements, and trust that their usage data is processed locally without being sent to third parties.

Possible disadvantages

  • Limited to Claude Code
    The tool is specifically designed for Claude Code usage tracking and may not cover all Claude API usage scenarios, limiting its usefulness for users who interact with Claude through other interfaces or custom API integrations.
  • Basic Visualization
    The tool outputs data in a terminal/CLI format without graphical charts or dashboards. Users looking for rich visual analytics, trend graphs, or exportable reports may find the presentation limited.
  • No Alerting or Budget Features
    The tool lacks built-in alerting mechanisms or budget-setting capabilities. Users cannot set spending thresholds or receive notifications when costs exceed certain limits, requiring manual monitoring.
  • Dependent on Local Log Data
    The tool relies on locally stored Claude Code session data. If logs are incomplete, corrupted, or cleared, the cost tracking will be inaccurate or unavailable, and there's no server-side verification of the data.
  • Limited Configuration Options
    The tool offers relatively few customization options for filtering, date ranges, or output formats. Power users who want more granular control over their usage analysis may find it insufficient for advanced use cases.
  • Supported Agents
    18+ (Claude Code, Codex, Gemini CLI, Aider, Cursor, Amp, Roo Code, Goose, Kilo, Kiro, OpenCode, Tabby, and more)
  • Orchestration Model
    Deterministic Python (zero LLM tokens on scheduling)
  • Git Isolation
    Per-agent worktrees — main branch stays clean
  • Verification
    Automated janitor: tests, lint, types, PII scan
  • Model Routing
    Contextual bandit (LinUCB) learns optimal model per task type
  • Cost Tracking
    Built-in per-model, per-task cost reporting
  • Plan Execution
    Declarative YAML plans with stage dependencies
  • CLI Interface
    TUI dashboard, headless mode for CI, web dashboard
  • Self-Evolution
    --evolve mode analyzes own metrics and improves routing
  • Crash Recovery
    WAL-based — no silent data loss
  • Observability
    Prometheus metrics, OpenTelemetry, Grafana dashboards
  • MCP Support
    MCP 1.0 & 1.1 server mode
  • A2A Protocol
    A2A 0.2 & 0.3 compatible
  • License
    Apache 2.0
  • Install Methods
    pip, pipx, uv, Homebrew, dnf copr, npm wrapper
  • Platform
    macOS, Linux (Windows via WSL)
  • State Storage
    File-based (.sdd/ directory) — no database required

Questions & Answers

As answered by people managing Claude Usage 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...
