Bernstein

No description of PuTTY 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.

PuTTY 5 features
Bernstein 17 features
  • Free and Open Source
    PuTTY is free to use and its source code is openly available. This allows flexibility for users to modify it according to their needs and ensures that there are no licensing costs associated with its usage.
  • Wide Protocol Support
    PuTTY supports various network protocols including SSH, Telnet, SCP, and SFTP. This makes it versatile for different types of server management and data transfer tasks.
  • Lightweight
    PuTTY is a lightweight application that consumes minimal system resources, making it suitable for use on older or less powerful systems without significant performance degradation.
  • Extensible Configuration Options
    PuTTY offers a wide range of configuration options for terminal emulation, keyboard mappings, and connection settings, giving users fine control over their connections and workflow.
  • Portability
    PuTTY can be run as a portable application from USB drives or other external storage devices without the need for a formal installation process on the host system.

Possible disadvantages

  • No Integrated File Manager
    Unlike some other SSH clients, PuTTY does not come with an integrated file manager, which can make tasks involving file transfers less convenient without the use of PuTTY's separate utilities like PSCP or WinSCP.
  • Limited Scripting Capabilities
    PuTTY itself lacks advanced scripting capabilities which can be a limitation for users who need to automate sessions or workflows extensively. External tools or extensions are necessary for these needs.
  • Basic User Interface
    The user interface of PuTTY is quite basic compared to modern applications. It lacks some of the polished features and aesthetics that other terminal clients might offer.
  • No Tabbed Sessions
    PuTTY does not natively support multiple tabbed sessions within a single window, which can make managing multiple connections less convenient. Users typically need to open multiple instances of the application.
  • Windows-Centric
    While PuTTY is primarily developed for Windows, its cross-platform capabilities through ports like PuTTY for Mac or Linux are not as well-supported, leading to potential inconsistencies and lack of features compared to the Windows version.
  • 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

Questions & Answers

As answered by people managing PuTTY 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...
