Alethio
Alpha opening soon Follow @uarayon

For vibe coders and software engineers

One setup, one record, one budget for every coding agent.

Alethio runs your coding agents on every machine you own (Mac, Windows, Linux or a cloud server) as one system. Add your skills, MCP servers and knowledge once, and every agent gets them. See every step they take and what it cost, from your desk or your phone.

The problem

Every new agent adds another setup to maintain.

Each harness is good at something, and each new model works best in a different one. So you run several, and you pay for it in upkeep, attention and lost work.

01

Each harness keeps its own copy

Skills, MCP servers, instructions and project knowledge are written again for every tool, in every tool's format. Then they drift apart.

02

Each machine is an island

Your laptop, your desktop and a cloud server each need their own install, keys and setup. An agent on one can't hand work to an agent on another.

03

Nobody can say what happened

Prompts, tool calls, spend and file changes are spread across terminals. When a run goes wrong or costs too much, there is no single record to read.

What makes Alethio different

Not another window for your agents. One system under all of them.

Alethio doesn't replace the harnesses you use. It runs them, on your machines, behind one setup, one record and one set of rules.

Set it up once. Every harness gets it.

Your skills, MCP servers, instructions and knowledge live in one place. For every session, Alethio writes them into the harness's own format, so an update to one skill reaches every agent.

Less to maintain with each harness you add, not more.

Every event, one level deeper.

Every prompt, model call, tool call, approval and message between agents goes into one append-only record. Every screen is built from it, and any summary opens down to the raw event.

Every version of your code is a git commit that names the agent, harness and model that made it.

Your keys never reach the agents.

A gateway on your machine holds your provider keys and prices every model call. Each harness gets a short-lived token that works only on that machine, only while its session runs.

Every MCP tool call goes through one hub that enforces your rules, the same for every harness.

Teams of agents, with a budget.

Any agent can hand part of the work to another harness, on another machine: Claude Code leads, Codex writes the tests on a cloud server, Pi reviews.

Budgets and limits apply to the whole team. Alethio spots deadlocks and stuck agents, checks every result before it is accepted, and lets you stop any branch of the team.

Every machine you own, one system.

Your laptop, the desktop in the other room, a home server and cloud machines on AWS or Google Cloud join as equals, whatever their OS. Each session goes to a machine that has the harness and the project it needs.

The control plane runs on your own machine or on Cloudflare, keeps a copy of its state on the other, and moves between them without losing a session. Close the laptop and the work goes on.

Two ways to work

Say what you want, or choose every detail.

Whether you want to describe the result and get on with your day or tune every run, it's the same product, the same agents and the same record.

Say what you want

Describe the result in your own words. A recipe picks the agents, harnesses and models. You hear from them only when a decision is yours or the result is ready, and they stop and ask before spending more than your limit.

for software engineers

Choose every detail

Pick the harness, model, effort, machine and workspace for each run. Read the raw events, set the tool rules, and shape the team: who spawns whom, with what budget.

Switch at any time. Every high-level view opens into its detail in one click.

A few clicks

Wherever you are, on whatever you have.

No config files to write. Install the app, pair your devices with a code, and your agents follow you from the desk to the phone.

  1. Install the app

    One install runs everything a machine needs. The harnesses you already use keep their own sign-in.

  2. Add your machines

    Each machine joins with a one-time code: the desktop, the home server, a cloud server.

  3. Pair your phone

    Scan a code. Start tasks, follow them live and answer approvals from anywhere.

Alpha

Alpha opening soon.

We're opening Alethio to a small group of vibe coders and software engineers who already work with coding agents. The date will be announced on X.
