Stonepair LLC / AI engineering platform

The control plane for
self-running engineering.

Stonepair pairs your systems with the leading frontier models to automate development and infrastructure work, then proves and records every action under one auditable plane.

01 — Capabilities

Three workloads. One plane.

/01

Intelligent
automation

Pipelines, infra changes, and routine operations handled end to end. Stonepair reads intent, plans the work, and closes the loop, asking for a human only where judgment matters.

  • CI / CD
  • Infra-as-code
  • Drift reconciliation
/02

Code
assistance

Context-aware code grounded in your repository, conventions, and history. Not autocomplete in a vacuum: changes that understand the system they land in, with the tests to prove it.

  • Repo-grounded
  • Tree-wide refactors
  • Tests included
/03

Operational
tooling

Operations you can stand on. Runbooks that execute, incidents that triage themselves, and a record of every action taken, so the platform stays legible while it works.

  • Executable runbooks
  • Incident triage
  • Full audit
02 — The control plane

Intent in. Verified work out.

Stonepair sits between your repositories, your cloud, and the frontier. Every step is grounded in real context and recorded for review.

  1. ground

    Connect context

    Repos, cloud, tickets, and docs become one grounded model of how your system behaves.

  2. route

    Match model

    Each task routes to the frontier model that fits it, by reasoning, latency, and cost.

  3. execute

    Do the work

    Code written, infrastructure changed, operations run, inside your guardrails.

  4. verify

    Prove and record

    Tests, checks, and an immutable trail confirm every action before it counts as done.

03 — Model layer

Model-agnostic by design.

The frontier moves every quarter. Stonepair is built so you never re-platform to keep up. We route each request to the strongest available model and carry your context across all of them.

reasoning

Deep, multi-step tasks routed to the strongest reasoning models for planning and review.

code

Repository-scale edits sent to models tuned for software, with your conventions in context.

fast_path

High-volume, low-latency work handled by lightweight models, kept cheap and instant.

failover

Provider outages and rate limits handled automatically. The work does not stop.

04 — Cloud subscription

Priced like infrastructure.
