Build any software from a browser.

War Factory is a coding agent and dev environment. Describe what you need: a fix, a feature, a tool or a whole app. The agent writes it, runs it and tests it on a server. Every step lands in one thread your team can read, steer and share.

Note

In development at Irongold. Figure 1-1 shows examples, not customer work.

1-2 What it does

Ask for a change. Get a diff.

The agent’s edits show up in the thread as diffs, next to the commands it ran and what they returned.
Ask for an app. Get a URL.

Apps run in their own sandbox at a stable address on a separate domain, so you can open them and try them.
Close the laptop. It keeps working.

Work runs on the server, not in your browser. Reopen the thread from any device and pick up where it is.
Share the thread. A teammate can steer.

Share read-only or read-write. Anyone with write access can steer the agent, queue a follow-up or stop a turn.
Start from a file. Get a tool.

Upload a spreadsheet or a folder of documents and the agent builds on them. Apps use only the data you upload or enter.
Pick it up on your phone.

Prompting, steering, reviewing diffs and previewing apps all work at phone width, not just reading.

1-3 Nothing to install

The agent works in a sandbox on a server. Your machine needs a browser and nothing else. That matters on locked-down laptops where nobody can install a tool.

1-4 The thread is the record

Every prompt, tool call, diff and decision stays in the thread, with who did it. A reviewer reads what happened, not a summary of it.

1-5 Status

In development. Access is by invitation.

Caution

It runs on commercial cloud with commercial models. Do not put CUI or other controlled data in it.

It is built so the sandboxes and models can move later, into an enclave and onto DoW model endpoints. Neither is available yet.
