Fleet management system demo: 4 live apps built by AI models
Every app below is a working fleet management system, built by an AI coding model from the PlanSmith Fleet Management planner — running, with sample data, not a mock-up. Open one, sign in with the demo account it shows, and try it.
Open one and try it.
LiveFleet register with real custody
“FleetOrbit” — a ten-vehicle service fleet from onboarding through inspection, defect, work order and fuel to cost per mile. Each unit carries status, availability, assigned driver, odometer, open defects and next service due, and the record opens onto its own history. The build scored 98 in the four-model build-off: roles are genuinely separate — the administrator is refused a screen the fleet manager owns, and a driver sees only their own assignment. Sign in at /login with dana@meridianfleet.example (fleet manager) or marcus@ (technician), rosa@ (driver), priya@ (administrator), password MeridianDemo!2026. You land on its public service-request page; sign in from there. Its one-click demo sign-in is switched off in production on purpose, so the credentials live here rather than on the page.

LiveThe same planner, twenty points lower
“Harborline Fleet” — worth opening next to FleetOrbit, because the two were built from a byte-identical planner package. The foundation is strong: it is the only build of the four whose full 42-check suite re-runs cleanly from an empty database, and it ships a second company in its own data purely to prove customer separation. The product on top is thinner — thirteen of its sixteen workbenches are the same four-column table with different labels, so Fuel has no gallons and Costs has no amount. Its first audit also found three of the four roles unable to create anything; that was repaired and it was rescored 65 → 78. Demo buttons on /login sign you straight in as manager, driver, technician or administrator.

LiveThe one with the front door
“Roadstead Fleet” — the same planner again, and the only build of the four that refuses a stranger properly: every staff page redirects a visitor without a session to a sign-in screen, an address that does not exist returns a real not-found, and a cross-origin request to the login endpoint is rejected outright. Sign-in tokens and customer tracking links are both stored scrambled, so reading the database hands you neither. It arrives locked by default — this demo has its role buttons switched on deliberately, while the one-time owner claim stays off. You land on its public front door; sign in from there and pick a role.

LiveThe richest data model, after repair
“FleetFlow” — the fourth build from the same planner package, and the one that models a fleet most thoroughly: fuel with gallons, odometer and cost per fill, geofences with a radius, parts with reorder levels, purchase orders with vendors. It is also the only build that wires features to each other — a failed item on a pre-trip check raises a linked critical defect, takes the vehicle out of service, and a technician turns that defect into a work order and closes it out. It arrived unpublishable: the front end signed every visitor in as the fleet manager on page load, there was no sign-in screen at all, and its first-run setup accepted anonymous requests, so a stranger could rename the company. Those are closed — an anonymous request now gets 401 on every endpoint, including setup. It also used to write a fixed fuel-efficiency figure whenever it could not calculate one, under a heading that said “Calculated MPG”; a first fill-up now correctly reports nothing at all. Pick a role on the sign-in screen to get in.

| Rank | Build | Model | Score | In one line |
|---|---|---|---|---|
| 1 | FleetOrbit | Claude Fable 5 | 98 | The one to copy. Nothing we tried to break came apart. |
| 2 | Roadstead Fleet | GPT-5.6 Sol | 93 | The most carefully secured build here — and the one you can least easily run on your own machine. |
| 3 | FleetFlow | Gemini 3.7 Flash | 85 | The richest product here, and the front door is shut now. Rescored after repair, 72 → 85. |
| 4 | Harborline Fleet | Grok 4.6 | 78 | Sound foundations, thin product. Good if you intend to fill the features in yourself. |
Scores are as found at audit. The full findings for every build — what it does well and what we found — are on the fleet management build-off board.
