Spec-first AI app builder

Describe a feature. Get a spec, then code you own.

A PRD, a technical scope, and production code — not a prompt you hope holds together. See the software factory, or the source-code ownership route.

Codalio PRD canvas: business and technical requirements before the build

A plan you can actually read.

Users, workflow, and what done looks like — written down so engineering is not inventing the product in a prompt box.

Start building
RoamStay dashboard with rooms, arrivals, and live occupancy

A working app, not a demo.

Screens that match the plan. Logins, dashboards, and the flows your business already runs.

User flows from a Codalio PRD

The flows, captured before code.

Step-by-step paths through the product — so engineering is not inventing the workflow in a prompt box.

How it works

  1. Step 1

    Start with the business outcome

    Define what the app must do, who it is for, and what success looks like before features pile up.

  2. Step 2

    Reduce the release to a buildable scope

    Turn the feature into a clear MVP boundary with the right user flow, data needs, and product priorities.

  3. Step 3

    Move from plan into implementation

    Use the PRD and technical scope to create a cleaner handoff into code, launch, and future ownership.

Start building
Apply changes to GitHub — code you own

The code is yours.

Production-ready code and a handoff path — so the product still works after the first vendor, the first hire, and the first launch.

AI thinking orchestrator working through a Codalio spec

The factory thinks before it ships.

Orchestrated reasoning against the spec — not a one-shot prompt you hope held together.

Frequently asked questions

Vibe coding optimizes for the moment the screen looks right. Codalio optimizes for the spec the code is built from — so you don’t rebuild the same MVP three times. AI coding tools are calculators; Codalio gives them the brief.

Yes. Source-code ownership is part of the route. Repository access, deployment readiness, and a clean handoff are how Codalio is positioned against lighter, lock-in heavy builders.

No. Founders, product managers, and engineering leads all use the workflow. The planning steps are made for non-technical buyers, while the deliverables stay credible to engineers.
