00 — AI harnesses & dev tools

Tools for peoplewho buildwith agents.

Valoir ships AI harnesses and developer tooling — lean, opinionated, frictionless to connect. Open-source core, premium power.

01 — Manifesto

Built by a developer, for developers.The heavy machinery should be one toggle away — never shipped into the default view.Open-source at the core. Premium where the work earns it.

Most agent harnesses are broad and heavy. Valoir bets the other way: the lightest front door that still scales to hard projects. The moat is execution, taste, and the lightweight constraint held honestly — not a patentable trick. We say that plainly.

02 — Products

Products

One flagship today, architected so the next is one config edit. Each product carries its own license, install path, and — when ready — a live demo.

Rizz

The lightest, most connectable coding agent harness.

Rizz is a CLI-installable coding agent loop — model-call, tool-dispatch, tool-result, repeat, with interrupt, compression, budget, and fallback. Single-agent and minimal by default. Hermes-class power on demand behind an opt-in /workspace switch.

Early build · M2 walking skeleton

Extremely lightweight
Minimal dependencies, fast cold start, small footprint — enforced by a CI footprint budget, not by good intentions.
Provider-agnostic
Subscription /login, BYOK, or cloud creds across a curated catalog — Claude, Codex, OpenRouter, Bedrock, Ollama. Hot-swap models with no restart and no code changes.
A hub, not an island
Callable by any tool — print/JSON, RPC, SDK, MCP/ACP — and connects to Cursor, Claude, and Codex rather than replacing them.
Power on demand
Plan mode, parallel git-worktree agents, shared memory, and the greploop PR gate ship as opt-in /workspace power — never default bloat.

03 — Open Source

Open at the core.

Code lives in Git, not in slideware. The Rizz core flips to open-source (MIT, like Pi) at v1, with any paid layer kept separate — classic open-core.

04 — For developers

Install. Run. Connect.

One command to install, one command to run, and your existing model subscription or key. The loop gets out of the way.

Install

$brew install valoir/tap/rizz

Ships via the Valoir Homebrew tap at v1. Prefer source today? Build from the monorepo on the right.

05 — Roadmap

Rizz is the first, not the last.

The product config is built so the next tool is one object edit. Demos and live 'try it yourself' embeds slot in when they ship.

Now

Rizz — walking skeleton: one-command install, TUI, the loop on a Claude subscription.

Connectivity: Claude / Codex / Cursor / MCP adapters, and the eval harness.

Then

/workspace: parallel worktree agents, shared memory, the greploop merge gate.

Later

v1: core flips to open (MIT). More Valoir tools. Live demos on this site.
