Private beta · agent execution farm

Your frontier agent leads.
Stewie handles
scoped execution.

Stewie Agent Farm gives your coding agent a cost-efficient execution team for the grunt work. It dispatches, the farm returns finished patches and tests, it merges — all under the hood. You don’t manage the workers. You just get more done per session.

Not another background agent. The execution farm behind the ones you already use.

The problem

Frontier tokens are too expensive to spend on grunt work.

You burn your best agent — and your quota — writing fixtures, fixing lint, and grinding through repetitive migrations. The judgment work that actually needs a frontier model waits behind a queue of mechanical edits.

cost
Quota gone by noon

Every scoped refactor and test pass runs at frontier prices. Heavy Claude Code and Codex users hit limits doing work a cost-efficient worker could finish just as well.

focus
Context lost to busywork

Your lead agent context-switches from architecture to renaming variables. The plan degrades every time it drops into the weeds.

throughput
One agent, one thread

Implementation is serial. You wait while one agent grinds, instead of fanning ten scoped tasks out in parallel and reviewing the results.

How it works

From dispatch to merged patch.

Your agent leads at every step. Stewie only handles the scoped execution in between — and hands the result straight back to your agent.

your frontier agentstep 1 / 6

Your agent dispatches

Your coding agent calls Stewie through MCP, CLI, or a plugin — handing off a scoped chunk of work straight from its own plan. Nothing new for you to drive.

Durable product memory

Delegation creates the artifacts solo builders skip.

Solo builders rarely stop to write specs, plans, or decision logs. Intent stays in your head, and the reasoning gets buried in noisy chat transcripts you never read again.

Stewie Agent Farm makes the handoff do the work. Every scoped task leaves behind the contract, constraints, acceptance criteria, patch, tests, logs, and evidence needed to understand the change later.

Spec-driven development, out of the box. You get a durable product memory as a side effect of delegation — not as extra ceremony.

Use cases

Offload the mechanical. Keep the judgment.

The farm is built for well-scoped, verifiable work. High-stakes decisions stay with you and your frontier agent.

Great for the farm
Test writing
Unit, integration, and snapshot coverage for a named module.
Lint & type fixes
Clear the backlog of eslint, tsc, and formatter errors.
Repetitive migrations
Codemods and API renames applied across many files.
Scoped refactors
Extract, rename, restructure inside an explicit boundary.
Docs & examples
Docstrings, README sections, runnable usage samples.
Fixtures & seed data
Realistic test fixtures and factories from a schema.
Keep on your frontier agent
Product decisions
What to build and why stays with you.
Auth, security & billing
No unsupervised changes to sensitive paths.
Production deploys
The farm never ships — you press merge and deploy.
Architecture choices
System design needs frontier judgment, not outsourced labor.
Why not just sub-agents?

Your sub-agents don’t grind — they delegate.

Sub-agents keep your lead context clean — but they still run on your frontier model, your quota, your bill. Stewie keeps context clean and moves the work off your bill, onto a cost-efficient crew your agent simply hands scoped work to.

Native sub-agents

Isolate context in a child window — good, but that's all they isolate.

Run on your frontier model — same tokens, same quota, same bill.

Spawning ten drains your rate-limit faster, not slower.

Ephemeral — born, run, gone. No memory, no specialization.

Run in your agent's runtime — no sandbox, contract, or audit trail.

The Stewie farm

Isolates context and cost — execution detail stays on the farm.

Runs on a cost-efficient crew outside your quota.

Fan out ten scoped tracks in parallel without touching your frontier limit.

Durable — keeps project context across sessions, with specialist workers.

Runs in an isolated sandbox — returns evidence + tests against a contract.

Stewie doesn’t replace sub-agents — it’s what they delegate to. Same MCP seam your agent already uses; instead of a sub-agent grinding on expensive tokens, it hands the scoped work to the farm.

Safety & ownership

Your agent owns the merge. Stewie never touches main.

Workers run in isolation and hand evidence back to your agent — not commits. Nothing reaches main or production unless your agent, and you, approve it through the workflow you already use.

Isolated environments

Each worker runs in a clean, sandboxed clone — no shared state, no access to your secrets.

Patches, not commits

Diffs, tests, and logs go back to your agent as a bundle or draft PR — never a silent commit.

Your agent gates the merge

Nothing lands on main or deploys until your agent — and you — approve. Stewie adds no extra step.

Full audit trail

Every run records its contract, commands, and evidence. Reproducible end to end.

Pricing

Pay for execution, not frontier tokens.

Billed by worker execution minutes — not tokens. Your $100-a-month agent should spend its quota on planning and review, not burn it on execution. The farm covers that layer.

Billed by execution time — one minute of worker run time. You set a hard cap; the farm stops taking new work at it and tells your agent why, so you never pay past a ceiling you chose. Metering gets more granular as the farm matures.
