use the right agents in parallel.
ship work that survives evidence.

Choose the manager. Koryphaios coordinates the user-enabled agents, keeps serious attempts isolated, and makes their evidence, changes, and costs inspectable before anything lands.

Parallel attempts. Human control. Evidence before claims.

Download desktop

This guided, read-only sample uses the actual Koryphaios interface. It cannot run providers, terminals, or local files; download the desktop app for a real workspace.

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.

A team you control. Evidence you can inspect.

Choose the manager and eligible agents. Koryphaios coordinates bounded work, records the evidence, and keeps the final decision visible.

Youinput

Set the outcome and choose the manager. You stay in control of who can act.

Kory (Manager)orchestrator

Builds a task contract, then selects only from the workers and critics you enabled for that task.

Workersisolated worktrees · parallel

Specialists can run simultaneously in separate git worktrees. Koryphaios reports each provider's real execution and isolation boundary instead of calling every CLI sandboxed.

Criticread only · quality gate

Returns structured findings and evidence gaps. Review and acceptance remain visible decisions, not a promise of perfect code.

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.

Real interface

See Koryphaios at work.

Captured from the actual guided Koryphaios frontend—not a rendered concept or a replacement marketing UI.

Koryphaios coordinating specialist agents in an analytics dashboard project — A live project session with provider, effort, permission, critic, context, and cost state visible.

Koryphaios showing an authentication refactor session — A second project run showing session history, evidence, costs, and a rollback-aware result.

Built different.

Evidence-Gated AI Team

Critics return structured findings and verification evidence before you accept a change. Confidence is visible; certainty is never faked.

Reviewable quality signals

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

Run bounded attempts in isolated worktrees, then compare the actual diffs and evidence before deciding what belongs in your branch.

Parallel attempts, deliberate merges

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

Your Agents. One Workspace.

Connect subscriptions, APIs, local models, and tools. Koryphaios shows the provider-reported capabilities instead of guessing what a model can do.

Choice without fiction

Your Code Stays Yours

The coordinator and encrypted app data stay local. Only the context you choose is sent to the model provider you selected; native CLI permissions remain visible rather than being described as stronger isolation.

Local control, explicit boundaries

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 and the operating system webview, with no bundled Electron or Chromium runtime. Package size and memory vary by platform and workload.

No bundled Electron runtime

Your agents. One workspace.

Connect subscriptions, API providers, and local models in one place. The desktop registry currently contains 94 connections, and refreshes models from configured providers at runtime. This is a curated front door to that live registry—not a frozen compatibility grid.

OpenAI API, managed OpenAI Codex sign-in, and local Codex CLI login are separate connections. Provider costs and terms remain provider-specific.

Free. No catch.

Apache 2.0 licensed. Full source. No telemetry. No vendor lock-in. You pay your providers directly at their published rates — we add no markup, no fees, no hidden costs. The code is yours.

No Subscription

No monthly fee, no tiers, no seat licenses. Clone the repo, add your API keys, start building. All features unlocked. Forever.

Full Source

Apache 2.0 license. Fork it, modify it, build on it. TypeScript frontend + Bun backend + Tauri desktop — fully auditable.

Your Keys, Your Data

No cloud proxy. No analytics. No telemetry. API calls go directly from your machine to your providers. We never see your code, your prompts, or your keys.

Let the agents work.
You go ship.

Clone the repo. Add your API keys. Start a session. Koryphaios handles orchestration, review, cost tracking, and undo. You handle the vision.
