Get More Done, Faster and Cheaper.
Zenborg is a desktop app for macOS and Windows that connects the AI coding agents you already use—Claude Code, Codex, Gemini, OpenCode, Hermes, etc.—into automated loops. One agent plans, a cheaper worker writes the code, and a reviewer checks every diff in an isolated git worktree before you even look at it.
Slash Your Token Costs
Keep your expensive flagship model for planning and final review while delegating heavy coding to fast, low-cost or free worker models.
Stop Copy-Pasting Between Terminals
Hand off a task once—Zenborg runs the plan, execution, tests, and code review automatically until it passes.
Zero Broken Branches
Every loop runs in its own isolated git worktree on your Mac or Windows PC, so your main branch stays clean.
Stop Babysitting Your AI Agents.
Tired of watching terminal output line by line and burning your weekly Claude or Codex quota on routine bug fixes? Zenborg runs your existing AI CLIs as a coordinated local team that plans, codes, tests, and self-corrects in the background—and automatically switches models when one hits a limit.
Automatic Quota & Large-File Fallback
If an agent hits a rate limit or a file is too large for a browser agent, Zenborg's Smart Worker automatically takes over without losing progress.
Built-In Code Review Before You Look
A dedicated reviewer agent checks every change against your acceptance criteria and sends mistakes back for fixing automatically.
Works From Your Favorite Client
Trigger Zenborg loops and multi-agent discussions directly from the Zenborg app or via MCP from Claude Code, Codex, Hermes, or Antigravity.
Turn Your Solo AI CLI Into a Manager → Worker → Reviewer Team.
One AI agent working alone makes mistakes and grades its own homework. Zenborg pairs your installed AI agents on macOS and Windows so a Manager plans the change, a Worker implements it in an isolated git worktree, and a Reviewer verifies the tests before you merge.
Manager → Worker → Reviewer Loops
Structured multi-stage execution that catches regressions before they reach your repo.
Multi-Agent Brainstorming & Debate
Put Claude, Codex, Gemini, OpenCode, Hermes, etc. in one room to stress-test architecture or marketing copy in seconds.
100% Local & Private
Everything runs on your machine using your existing CLI logins and API keys—Zenborg never uploads your codebase to a third-party cloud.
Get More Client Work Done, Faster and Cheaper.
Zenborg is the macOS and Windows desktop workspace that lets you run parallel AI agent loops across multiple client projects at once. Use top-tier models for architecture and review, route the heavy coding to low-cost worker models, and deliver verified features in a fraction of the time.
Keep Higher Margins on Every Project
Stop burning $200/month in flagship API credits on boilerplate—let cheap or free worker models handle implementation while a smart reviewer enforces quality.
Run Parallel Loops Across Client Repos
Ship a feature for Client A while a background loop fixes bugs and runs tests for Client B in isolated git worktrees.
Reusable Specialist Agents
Create custom agents with your own operating instructions, skills, and Google NotebookLM knowledge bases that work across every project.
Ship 3× More Projects Without Becoming a Full-Time Prompt Babysitter.
Your bottleneck isn't writing prompts—it's babysitting AI mistakes across five open windows. Zenborg automates the entire plan → code → test → review cycle on your Mac or Windows PC, so you only step in to approve finished, tested work.
Hand Off Complete Tasks, Not Micro-Prompts
Give Zenborg a goal and acceptance criteria; the loop iterates until the reviewer agent approves the diff.
Project-Scoped Organization
Keep every client's repo, sessions, loops, restore points, and specialist agents cleanly separated in one desktop app.
Built-In Restore Points & Safety
Roll back any project state in one click if an experiment goes in the wrong direction.
Your Local AI Dev Shop: A Manager, a Worker, and a Reviewer on Every Job.
Run a disciplined software delivery pipeline on your own Mac or Windows machine. Zenborg coordinates your AI agents so every feature is planned by a Manager, coded by a Worker in an isolated branch, and audited by a Reviewer before you deliver it to a client.
Automated QA Before Delivery
The Reviewer agent runs your test suite and rejects incomplete diffs before you waste time reviewing broken code.
Zero Cloud Lock-In
All client code stays 100% local on your machine—ideal for NDA and privacy-sensitive client work.
Usage Dashboard Included
Track every agent run, loop stage, and fallback across all your active projects.
Get More Done, Faster and Cheaper—with Your Own AI Tools.
Hit the credit wall on cloud builders that charge you extra every time their AI breaks your app? Zenborg is a free-beta desktop app for macOS and Windows that runs on your computer using the AI subscriptions and low-cost models you already choose—with a Reviewer agent that stops repair loops before they start.
No Per-Prompt Cloud Markup
Use your existing Claude, ChatGPT/Codex, Gemini, Hermes, or free/low-cost OpenCode models directly—no middleman credit packs.
A Second AI Checks Every Fix
Instead of one AI breaking Feature A while fixing Feature B, Zenborg uses a separate Reviewer agent to verify every change before it touches your project.
Your Code Lives on Your Computer
Open your project folder on macOS or Windows (available right in the Microsoft Store), with one-click Restore Points whenever you want to roll back.
Stop Paying Extra Credits for AI Repair Loops.
Cloud AI builders hook you with a fast prototype, then drain your wallet when the AI gets stuck breaking and re-fixing the same bug. Zenborg brings your project to your Mac or Windows PC and puts a Manager → Worker → Reviewer team on every change—so bugs get caught and fixed cleanly in an isolated workspace.
Break Out of the "Fix One Thing, Break Two" Trap
When a worker model gets stuck, Zenborg's Reviewer catches it and Smart Worker automatically escalates to a stronger model.
One-Click Restore Points
Never lose a working version of your app—save and restore snapshots locally at any time without paying for cloud hosting tiers.
Guided, Plain-English Workflow
You don't need to configure complex orchestration—pick your project folder, describe what you want to add, and let the loop run.
Give Your Project a Second Opinion—Not Another Broken Prompt.
When one AI model writes and checks its own code, you end up being the human debugger. Zenborg is a macOS and Windows desktop app that pairs multiple AI agents together: one plans your feature, another writes the code, and a second-opinion Reviewer verifies that it actually works.
Manager → Worker → Reviewer Quality Gate
Every change is planned, implemented, and reviewed before you see it.

Architecture & Bounds
Parsed Stripe API docs, generated 4 test vectors, configured isolated git worktree branch.
Isolated Git Worktree
Writing api/stripe.ts without touching your active editor or dirty branch.
Diff & Security Gate
Caught missing timestamp drift check. Demanded self-healing patch before presenting diff to you.
Engineered for Builders
Who Refuse Compromise.
Zero shared cloud containers. Zero token markups. Just brute local execution, isolated git worktrees, and pre-flight adversarial review.
Autonomous Parallel Loops in Isolated Git Worktrees
Web chatbots force you into shared containers and crash your dirty branches. Zenborg leverages native git worktrees: each agent plans, codes, and refactors in an isolated copy on disk, leaving your main branch pristine.
Unlock Hidden Plan Credits
Stop buying separate metered API keys. Zenborg taps directly into the generous, unused allowances already included in your Claude Pro, ChatGPT Plus, Gemini, Hermes, and other accounts.
100% Local-First & Private
Zero code leaves your machine. Your proprietary repos, environment secrets, and prompts are never routed through Zenborg cloud servers.
Adversarial Pre-Flight Review Before Human Eyes
Single models hallucinate subtle bugs and confidently break production. Zenborg pits an independent reviewer model against the builder: running automated test suites, auditing diffs, and requesting self-healing patches before you ever see a merge prompt.
Three simple steps. Then close your laptop.
No complex infrastructure, no cloud migration. Up and running in minutes.
Connect the tools you already have.
Link your Claude, ChatGPT/Codex, Gemini, OpenCode, Hermes, and other agent setups in one click. No new APIs to buy, no token surcharges, zero cloud lock-in.
Assign the job in plain English.
Type: "Build a Stripe checkout flow with webhook verification and test for edge cases." Zenborg automatically breaks it into a verified execution plan.
Walk away. Return to finished, bug-free work.
While you take a walk or work on something else, an isolated builder writes the code and an automated reviewer inspects the diff. Fixes happen autonomously until every check passes.
Watch Claude Code and Codex work one task together, with no copy-paste between them.
One real, timestamped session. It starts in the harness and ends with a merge you approve. Speed-ups are labelled.

You Already Pay for AI Quotas. Stop Buying Separate API Tokens.
If you have an active Claude Pro, ChatGPT Plus/Team/Pro, or Gemini subscription, you already own massive daily allowances. Cloud wrapper apps hide this and demand extra credit cards with per-token billing ($5–$30/day). Zenborg runs locally through your desktop CLI logins—unlocking your existing plan quotas so you build and refactor without paying an extra cent in API invoices.
