What Is an AI Software Factory? Coding Agents at Scale
An AI software factory is an infrastructure pattern where many coding agents run in parallel in the cloud, taking issues to reviewed pull requests with orchestration, code review, and CI loops. How it works, what makes it different from running one agent at a time, and how Murmur fits.
An AI software factory is an infrastructure pattern where many AI coding agents run in parallel in the cloud, each in its own isolated environment, taking issues from a queue all the way to reviewed pull requests ready for human approval. This is not about manufacturing execution systems (MES) or ERP software for physical factories. An AI software factory is for code: autonomous coding agents that write, test, and ship software changes continuously.
The factory includes orchestration to coordinate the agents, AI code review to validate their output, and CI loops to verify changes actually work. The difference from running one agent at a time is throughput: a software factory produces reviewed changes continuously, not one at a time when an engineer has a terminal window open.
TL;DR
- An AI software factory runs many coding agents in parallel in the cloud. Each agent gets its own isolated environment with your development stack running.
- Work flows from issues to merged PRs. Agents pull tasks from a queue, implement them, verify their changes, and open pull requests.
- Orchestration coordinates the fleet. The factory decides which agent handles which task, tracks progress, and handles dependencies.
- AI code review validates output. Without automated review, agents produce PRs faster than humans can read them, and the queue grows.
- CI loops verify changes actually work. Agents that can run tests and interact with a running application catch their own mistakes before opening a PR.
- Human approval remains the final step. The factory produces reviewed, tested changes. A person decides what merges.
What makes something an AI software factory?
An AI software factory has four components: a queue of work, parallel autonomous coding agent execution in isolated environments, automated validation (code review and CI), and orchestration that ties them together.
A queue of work
Work enters the factory from issues, Slack messages, Linear tickets, scheduled tasks, or human direction. The factory maintains a backlog and dispatches tasks to available agents.
Parallel autonomous coding agent execution
Each task gets its own autonomous coding agent running in its own cloud environment. Agents work concurrently without competing for the same machine, ports, or database. When one agent finishes, another task starts immediately.
Automated validation
Every pull request an agent opens goes through AI code review and CI. Review catches bugs, security issues, and violations of team conventions. CI verifies the change actually works. Together they filter out broken changes before a human looks.
Orchestration
Orchestration coordinates everything: spinning up agent environments, routing tasks, tracking progress, reacting to GitHub events (review comments, failing checks, merge conflicts), and reporting status. Without orchestration, each agent is a separate process you manage by hand.
How does an AI software factory differ from one agent at a time?
Running one agent at a time is interactive work. An AI software factory is continuous production.
| One agent at a time | AI software factory |
|---|---|
| You start each task | Tasks flow from a queue |
| One task runs while you watch | Many tasks run in parallel |
| Stops when you close the laptop | Runs continuously |
| You handle review comments and CI | Agents handle their own post-PR lifecycle |
| Output is one PR when you finish | Output is a stream of reviewed PRs |
The mental model shifts from "I am using an agent" to "I am directing a factory." Engineers focus on scoping work, reviewing output, and making decisions the factory cannot make.
What does the workflow look like?
Work enters as a task description, flows through agent execution and validation, and exits as a reviewed pull request ready for human approval.

Merge
Each agent works autonomously through its task: planning the approach, writing code, running tests, verifying against a running stack, and opening a pull request with evidence. After the PR opens, the agent responds to review comments, fixes failing CI, rebases when the base branch moves, and resolves merge conflicts.
Why does AI code review matter in a software factory?
Without AI code review, agents produce changes faster than humans can validate them. A factory with ten agents can produce ten PRs per hour. A human reviewer reading each one carefully becomes the bottleneck, and the queue of unreviewed PRs grows.
AI code review closes this gap. Macroscope Code Review reviews every PR with full-repository context, catching cross-file bugs that the agent might have introduced. Approvability auto-approves low-risk changes so humans focus on what needs judgment. Fix It For Me turns review findings into committed fixes.
The combination of agent production and automated review is what makes a software factory practical. Neither half works without the other at scale.
What infrastructure does a software factory need?
Each agent needs an isolated environment with your full development stack, credentials scoped to its task, and a connection to GitHub for the PR lifecycle.
Isolated environments
Agents that share an environment interfere with each other: one agent's database migration breaks another's tests, two agents claim the same port, a half-finished dependency upgrade corrupts the checkout. A software factory gives each agent its own VM.
A running stack
An agent with only a repository checkout can write code but cannot verify it. An agent with a running stack can boot services, run the test suite, interact with the UI, and attach evidence to its PR. Verification is what separates agents that produce mergeable changes from agents that produce plausible-looking diffs.
Scoped credentials
Each agent should reach exactly what its task requires. A staging bug-fix agent does not need production credentials. Service profiles define per-workload access, and repository confinement limits what repositories an agent can touch.
GitHub lifecycle integration
A PR is not done when it opens. Review comments arrive, CI fails, branches diverge. Agents connected to the GitHub lifecycle handle all of this autonomously, iterating until the change is ready for human approval.
How does Murmur fit the software factory model?
Murmur is Macroscope's platform for running many coding agents in parallel in the cloud, with each agent in its own VM, orchestration, and post-PR automation built in.
Murmur provides the infrastructure layer for an AI software factory:
- Agent-agnostic execution. Each agent is a Claude Code or Codex session on its own dedicated cloud VM. You bring your own API keys or subscriptions.
- Full stack per agent. VMs are provisioned with your repositories and development stack running, so agents verify their own work before opening PRs.
- Orchestration. Work enters from a local Director session, Slack, Linear, GitHub events, or scheduled Flights. The platform tracks agents and reports progress.
- Post-PR automation. Agents respond to review comments, repair failing CI, rebase, and resolve merge conflicts until changes are ready for human approval.
- Customer placements. Agent VMs can run in Murmur Cloud or in your own GCP project or AWS account.
For the agent orchestration layer specifically, see what is cloud AI coding agent orchestration. For the full comparison of platforms, see best coding agent orchestration tools 2026.
What tasks fit an AI software factory?
Tasks with clear requirements that can be verified programmatically fit well. Tasks requiring judgment or context outside the codebase fit less well.
Good fits:
- Bug fixes with reproductions. A failing test or clear reproduction steps give the agent something to verify against.
- Feature implementations from specs. Written requirements the agent can read and check its work against.
- Mechanical refactors. Renaming, API migration, syntax updates across many files.
- Repetitive changes. The same change across many services, repositories, or configurations.
Less good fits:
- Product judgment. Whether a feature should exist, what the UX should feel like.
- Requirements that live outside the code. Context from meetings, user research, business constraints.
- Ambiguous scope. Tasks where the agent would need to ask clarifying questions repeatedly.
The factory amplifies whatever you put into it. Clear inputs produce clean outputs.
How do you get started with a software factory approach?
Start small: pick one well-scoped task, run it through the factory, and expand once you trust the pipeline.
- Connect your GitHub organization to an orchestration platform like Murmur.
- Define your environment. Bake a VM image with dependencies installed so agents start with a working stack.
- Run one task. A bug fix with a clear reproduction is a good first test.
- Verify the output. Did the PR arrive green? Did the agent's evidence match reality?
- Expand gradually. More tasks, more parallelism, more types of work.
Murmur is in early preview. Teams can apply at /murmur-beta.

Frequently Asked Questions
What is an AI software factory?
An AI software factory is an infrastructure pattern where many AI coding agents run in parallel in the cloud, each in its own isolated environment, taking tasks from a queue all the way to reviewed pull requests ready for human approval. The factory includes orchestration to coordinate agents, AI code review to validate output, and CI loops to verify changes work.
How is an AI software factory different from using one coding agent?
Running one agent is interactive work: you start a task, watch it run, and handle the PR yourself. A software factory is continuous production: tasks flow from a queue, many agents run in parallel, agents handle their own post-PR lifecycle, and reviewed PRs emerge ready for approval.
What's the best platform for running AI coding agents in the cloud?
For a software factory approach with many agents in parallel, look for a platform with isolated VMs per agent, a running stack for verification, post-PR automation (review comments, CI, rebases, conflicts), and orchestration. Murmur is built for this model. For single-agent cloud tasks, several products exist with different tradeoffs. See best coding agent orchestration tools 2026.
Why does AI code review matter in a software factory?
Without automated review, agents produce PRs faster than humans can read them. AI code review validates every change, catches bugs, and filters out broken PRs before a human looks. Approvability auto-approves low-risk changes. The factory only works at scale when review keeps pace with production.
What tasks are good fits for an AI software factory?
Bug fixes with reproductions, feature implementations from written specs, mechanical refactors, and repetitive changes across many files. Tasks requiring product judgment or context outside the codebase fit less well. The factory amplifies whatever you put into it.
What is Murmur?
Murmur is Macroscope's platform for running many coding agents in parallel in the cloud. Each agent runs in its own dedicated VM with your development stack, and agents handle review comments, failing CI, rebases, and merge conflicts after PRs open. It is agent-agnostic (Claude Code or Codex with your own keys) and can run in your own GCP or AWS VPC. See the Murmur FAQ.
Can an AI software factory run in my own cloud?
Yes, with the right platform. Murmur supports customer placements where agent VMs run in your own GCP project or AWS account with your credentials, authenticated through short-lived OIDC tokens. Most single-agent cloud products are SaaS-only.
Does a software factory merge PRs automatically?
Not by default. The factory produces reviewed, tested changes ready for human approval. A person decides what merges. Murmur agents shepherd PRs until they are ready for approval but do not merge unless a human explicitly instructs them to.
