AWARD-WINNING DESKTOP ARCHITECTURE

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.

ZERO TREE CONTAMINATION

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.

Local Worktree Thread Pool● 3 concurrent agents active
main:clean, dev server running on localhost:3000
worktree/feat-stripe:Codex building Stripe webhook + unit tests
worktree/audit-tokens:Gemini reviewing AST diffs for edge cases
worktree/hermes-tests:Hermes auditing edge cases & test coverage
0% API MARKUP

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.

Separate API Invoices:$60–$180/mo per token
With Zenborg:$0 extra · Uses plan quotas

100% Local-First & Private

Zero code leaves your machine. Your proprietary repos, environment secrets, and prompts are never routed through Zenborg cloud servers.

✓Zero cloud code storage
✓Offline cryptographic license check
ADVERSARIAL REVIEW LOOP

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.

Frequently Asked Questions

Questions Builders Ask Us

Everything you need to know about local-first multi-agent loops, zero API overhead, and the free beta.

Do I need to pay for extra AI API tokens or wrapper credits?
No. Most developers already pay for monthly subscriptions (like ChatGPT Plus/Pro, Claude Pro/Team, GitHub Copilot, or Google AI Studio) that include generous daily quotas. Traditional wrapper tools force you to connect separate paid API cards with metered per-token billing that runs into hundreds of dollars. Zenborg connects directly to your existing desktop CLI accounts, unlocking the high-volume allowances you already own with zero per-token markups or surprise API bills.
Where does my source code go?
Nowhere. Zenborg is 100% local-first. It operates inside isolated git worktree directories directly on your Mac or Windows machine. Your code, keys, and prompts never touch Zenborg servers.
How does the multi-agent review actually catch bugs?
Zenborg runs an automated review loop: one model acts as the Planner, another builds the implementation in an isolated copy of your project, and an adversarial reviewer model inspects the diff against your goal - demanding fixes and self-healing patches before presenting you with the finished result.
What happens when the Beta ends?
Nothing is charged automatically. There are no surprise fees and no credit card is ever required. Your local projects, git worktrees, and data remain 100% on your machine. Beta testers are recognized as Founding Users and will receive exclusive grandfathered benefits when the commercial release arrives.
