Broad Daylight is Exowatt's open-source initiative: six tools a small team and its agents use to take code from a phone scan of a site, through simulation, to real hardware. This paper covers what each one does, the numbers we measured, and which parts are public today.

After a three-hour GitHub Actions outage, we built Roadrunner, a self-hosted Woodpecker and Dagger deploy lane. Eight days later it was the default deploy path for 199 repos, with GitHub Actions kept as the fallback.

How we built Copper Cloud, one Rust server that syncs browsers, pairs devices and relays agent calls to a phone, and how handing whole goals to a small action model brought a browser decision down to about 0.13 seconds.

Collin Rijock built OrbLang, a typed language that compiles physical sites into simulator scenes. Felipe Arce built the infrastructure around it: capture from phone scans, remote GPU rendering, a content-addressed project catalog, and the tools we present films and live simulations with.

Hypergoose gives every agent and internal app at Exowatt one key and per-identity grants to 20 outside services. Upstream secrets never leave the gateway, and every call carries the person it acts for. The identity model, the bug that shaped it, and what it handles today.

Every Exowatt site runs its energy management system on a small host at the plant. This is how we built the plane that provisions and upgrades those hosts without git, downgrades or avoidable downtime, and the WireGuard tunnel that brings each site's console back to the cloud.

In three days a DEXI-5 quadcopter went from its first real flight to flying a square on its own while a small text-only action model pulled it back from fan gusts. This is the loop, its rates, and what the simulator got wrong.

phi is our fork of the open-source pi coding agent. Three infrastructure decisions let a whole team run it: ship one binary promoted by tag, supervise subagents as real processes, and put one hub on every machine so a phone or another session can drive any session.

Forca is Exowatt's fork of Orca, the open-source agent workspace. We built the release feed that ships it and phi on every push, a contract that keeps us pairable with the stock phone app, and the method that merged 9,043 upstream commits in one afternoon.

We turned beads, an open-source issue tracker for coding agents, into Feads: one hosted board where nine people's agents claim work, declare the files they touch and @mention each other. Since July it has tracked 19,356 items and recorded 4,732 overlap decisions.

Every app and every engineer at Exowatt calls models through one self-hosted gateway that we can meter, upgrade and route from a single config file.

A small team inside a solar energy company that writes the software for our hardware and helps everyone else at Exowatt ship code with AI agents.

We forked a small WebKit browser for the Mac and made it an MCP server, so agents work in the browser you're already signed into.

How a manifest, one reusable workflow and a Claude Code plugin put 205 internal apps on our own servers in under six months, nearly half of them owned by people outside the software team.
