Koryphaios
Open Source

your AI agents are chaos.
this is the fix.

Describe what you want. Koryphaios spins up AI specialists that work together, check each other's work, and keep your git history clean. See costs live. One prompt. Multiple agents. No babysitting.

Built for engineers who ship with AI, not engineers who want to manage AI.

The Problem

You're the human router.

Switching tabs, comparing outputs, tracking spend across a dozen providers. You're not coding — you're managing infrastructure.

Too Many Tools

Claude in one tab, GPT in another, Cursor on the side. You're the glue holding it all together.

Surprise Bills

Different providers, different pricing, different billing cycles. The invoice arrives and it's always a shock.

No Safety Net

AI breaks your code and undoing means messy commits with no context about what was tried or what it cost.

Architecture

Agents that manage themselves.

One instruction. The system handles delegation, execution, quality control, and rollback.

Youinput

One prompt. The Manager handles the rest.

Kory (Manager)orchestrator

Classifies tasks, picks the best models, builds fallback chains, spawns workers in isolated git worktrees.

Workerssandboxed · parallel

Multiple specialists run simultaneously in separate worktrees. Each sandboxed to specific paths — no conflicts, no overwrites.

Criticread only · quality gate

Reviews all output before you see it. Returns PASS or FAIL with line-level feedback. Bad code never reaches you.

Shadow Loggerghost commits · undo

Every change stored as a dangling commit with cost, tokens, model, and prompt hash. Time travel to any state. Your branch stays clean.

Capabilities

Built different.

Self-Checking AI Team

Every change gets reviewed by a Critic agent before it reaches you. Bad code is caught automatically — not your problem.

Quality without the effort

Ghost Commits

Every AI change saved with full context — cost, tokens, model used. Clean git history, easy rollbacks. Know exactly what each change cost you.

Undo without the mess

Parallel Agents

Multiple AI specialists work on different parts at the same time without stepping on each other. Frontend, backend, tests — all at once.

Parallel execution, fewer conflicts

Real Time Cost Tracking

Per provider, per model, per session, per token — visible live as it happens. Running 6 agents across 3 providers? See exactly what each burns.

No more surprise bills

Works With Your Stack

Bring your own API keys for Claude, OpenAI, and 40+ providers. Plug in any MCP server or tool. No vendor lock-in.

Plays nice with others

Your Code Stays Yours

Local-first with encrypted storage. Agents only access what they need. No data sent to us — your API keys, your providers, your machine.

Privacy by design

Watch It Happen

See agents spawn, work, and finish in real time. No black boxes — you know what's happening and what it costs as it happens.

Full visibility

Native Desktop App

Built with Tauri: under 100MB native binary on Windows, macOS, and Linux. No Electron bloat, no VS Code subscription. System tray, native menus, local data.

Lean and native
Providers

Every model. One dashboard.

Koryphaios auto detects your API keys, routes to the best available model, and fails over automatically when a provider goes down. Circuit breaker pattern with fallback chains up to 25 models deep.
