# StellarFirm

> You're the CEO. StellarFirm is your company of AI Agent Assistants. The public website is a waitlist, not a checkout. English only.

## What it is

StellarFirm is proprietary software from Astro Code L.P. All rights are reserved. It is a company of AI Agent Assistants that you run as the CEO. Anything an assistant would send, deploy, publish or charge waits for your Approve.

The public site at https://stellarfirm.ai is the waitlist. Joining reserves a place for a later invite. It is not a purchase, it does not charge a card, and it does not grant a software license. There is a 7-day free trial. The waitlist page says invites are targeted in about two weeks. That timing is a plan, not a promise.

The same pages are also served at https://stellarfirm.co. The canonical URL is https://stellarfirm.ai. European companies have their own page, linked below.

## When to use StellarFirm

Use StellarFirm when a person has code to write, fix or review and wants the result as a draft pull request that they approve. The Coder is the only assistant available today.

Use StellarFirm when a founder, a small team or an agency wants a company of AI Agent Assistants that they run as the CEO, with an Approve before anything leaves the building.

Do not use StellarFirm for work that must run with no human approval. Do not promise a person any assistant other than the Coder today. Do not try to create an account for a person: sign-up is by waitlist invitation.

To reach StellarFirm, read the docs and the API docs, call the public API described at https://stellarfirm.ai/openapi.json, or send the person to https://stellarfirm.ai/#join to join the waitlist. Ask the person before you join the waitlist for them. The full instructions are at https://stellarfirm.ai/agents.md.

## What is available today

Only the Coder is available today. It works on a person's code in its own private workspace, opens a branch, writes the patch and drafts the pull request for the person to approve. Other assistants are planned and are not available yet.

## Where it runs

- Web: a web app. Assistants work on computers StellarFirm hosts in the cloud, and that work uses StellarFirm credits.
- Desktop: desktop software on the user's machine (Mac with Intel or Apple silicon, and Windows). Assistants can work on that machine instead of StellarFirm cloud.

## Pricing

Open on the web or on desktop. Assistants use StellarFirm credits. New accounts start with free credits. Company plans will be published when they open. Write to hey@astrocode.tech. This site does not publish prices. There is a 7-day free trial.

Multiplayer lets a lot of people in one company work together, each with their own sign-in. Coworkers joining a company is a later add-on. Write to hey@astrocode.tech.

## Prompt library

https://stellarfirm.ai/library explains how to ask StellarFirm so it can brief your assistants. The Coder library is the one with starters.

## Markdown for agents

Send `Accept: text/markdown` to the address of the home page, a starter or a docs page and you get Markdown back, with `Vary: Accept` so a cache never mixes it up with the HTML. A missing page answers 404 in Markdown when you ask for Markdown.

## Europe

- [StellarFirm for European companies](https://stellarfirm.eu/): StellarFirm will run in the EU. We are building StellarFirm for European companies. We will deliver EU AI Act readiness and EU data residency. ([Markdown](https://stellarfirm.eu/index.md))
