About MartinLoop
Overview
MartinLoop is an execution control system that runs around AI coding agents. It gives every agent run a budget, verifier, stop rule, and receipt before any change lands, without replacing the agent or model you already use.
Claude, Codex, and Gemini are the workers. MartinLoop runs the job around the work they do, right in your CLI or IDE. Agents do the work; MartinLoop governs the work.
Key Benefits
- Give coding agents more real software work without watching every step
- Keep each run inside a defined task, dollar budget, timebox, and success criteria
- Validate policies, budgets, allowlists, and risk rules before the agent starts
- Verify outcomes with an independent gate that checks rules, tests, and invariants
- Preserve an immutable JSONL record with rollback evidence for every run
- Use the agent or model you want while the system around the work stays the same
How It Works
Teams define a run contract â task, dollar budget, timebox, and success criteria â before the agent starts. MartinLoop validates policies, budgets, allowlists, and risk rules against the contract, then the coding agent plans and acts inside it. An independent verifier gate checks rules, tests, and invariants before anything is accepted.
Each run produces an immutable JSONL dossier with rollback evidence and ends with an explicit stop reason: success, budget, policy, or error. A human performs the final review before release or close, with the full dossier in hand.
Use Cases
- Engineering teams run coding agents in production with budgets and audit trails
- Platform teams enforce policies, allowlists, and risk rules across every agent run
- CTOs get a measurable record of what shipped and what it cost
- Teams keep one control system while switching between Claude, Codex, and Gemini
- Organizations preserve immutable run receipts and rollback evidence for governance
Why Choose This Product
MartinLoop is not another agent or another IDE â Claude, Codex, and Gemini remain the workers. The core is open source under the Apache 2.0 license, while the hosted dashboard and managed team features are commercial. Every run ends explicitly with a stop reason, so work never silently continues past its budget, policy, or scope.
MartinLoop Pros & Cons
- Core is open source under the Apache 2.0 license
- Agent-agnostic â works with Claude, Codex, and Gemini in CLI or IDE
- Every run gets a budget, verifier, stop rule, and receipt
- Immutable JSONL run record for auditability
- Rollback evidence lets any run be undone cleanly
Key Features
Run Contracts
Teams define task, dollar budget, timebox, and success criteria before the agent starts.
Policy Checks
MartinLoop validates policies, budgets, allowlists, and risk rules against the run contract.
Verifier Gate
An independent verifier checks rules, tests, and invariants before anything is accepted.
Immutable Dossier
Each run produces an immutable JSONL record of inputs, actions, outputs, and artifacts.
Rollback Evidence
Snapshots, diffs, and reversibility data let any run be undone cleanly.
Stop Reasons
Every run ends explicitly as success, budget, policy, or error â never silent.
Human Review
A human performs final review before release or close with the full dossier in hand.
Agent-Agnostic
MartinLoop runs the job around Claude, Codex, Gemini, or another agent in your CLI or IDE.

Frequently asked questions about MartinLoop
What is MartinLoop?
MartinLoop is the execution control system around AI coding agents. Every run gets a budget, stop rule, verifier, rollback path, and receipt â without changing which agent or model you use.
Is this another coding agent?
No. Claude, Codex, and Gemini are the workers. MartinLoop runs the job around the work they do, right in your CLI or IDE. There is nothing to migrate to.
Is MartinLoop open source?
Yes. The core is licensed under Apache 2.0. The hosted dashboard and managed team features are commercial.
Who is MartinLoop for?
Engineering teams, platform teams, and CTOs running AI coding agents in production who need control, auditability, and a record of what happened.
Is MartinLoop free?
MartinLoop offers a free plan with optional paid upgrades. See the pricing section for what's included in each tier.
