Welcome to the factory floor
Your software deserves a factory.
Clock in your agents.
Gas City turns coding agents into a production line: beads on the belt, formulas driving the factory floor, judges at the gates, and humans running the factory instead of babysitting every session.
The tour
One bead enters. A factory wakes up.
A software factory is not a chatbot with a bigger prompt. It is a system that continuously plans, builds, reviews, tests, ships, and learns from signals. Gas City gives professional software engineers the platform to build that factory for their own codebase.
A bead hits the belt
Work becomes durable before any agent touches it. A bead is the unit of work the factory can route, inspect, retry, group, and audit outside any single agent session.
The light half sketches the job
Humans stay visibly in the loop where judgment matters: requirements, design, architecture, and review. The output is not vibes. It is the artifact the dark half can build from.
The dark half starts the night shift
Formulas run the production line while you do other work: fan out to multiple providers, pass context between sessions, unstick workers, and keep going until the checks pass.
Judges guard the gate
A script can launch five agents. The factory decides what happens when one fails at step four. Reviews, tests, exec checks, and judge consolidation keep non-deterministic agents inside production rails.
The factory proof
Features, schedule, quality: pick three.
The cards summarize org-wide GitHub activity from the public repositories in the gastownhall GitHub org that the Gas City factory manages. The old trade-off assumed handcrafted code; the factory changes the constraint by letting many agents work in parallel under the same quality bar.

Under the brass hood
Your agents have the skills. Gas City gives them an engine.
Multi-provider from the core
Claude Code, Codex, Gemini, OpenCode, and more can work the same line. Pick the right worker for the job and swap providers with config.
Formulas, not folklore
Sequential steps, fan-out, loops, human gates, judge consolidation, and deterministic exec orders make orchestration inspectable instead of improvised.
Packs are engineering judgment you can install
Gas City is the platform; packs are the apps. Publish, fork, and install runnable factory knowledge through the Registry.
Choose your door
Build the factory. Let Gasworks run it.
Gas City is open source and self-hostable. Gasworks is managed factory operations with a full-featured GUI from any device. The same factory idea, with the amount of ops you want.
Who is running this place?
A factory built by people who ship developer tools.
Gas City is built by the team operating its own public software factory: Chris Sells, Julian Knutsen, Steve Yegge, and D. Box.
