1. Pick a manufacturer
Use the tabs near the top — Dell and Apple are live. Lenovo is marked "Coming soon" and can't be selected yet.
2. Enter service tags or serial numbers
Type or paste one or more into the box — one per line, or separated by commas or spaces. Up to 20 at a time. Click Look Up Information (or press Ctrl/Cmd + Enter from the box).
For Apple, if more than one Apple School/Business Manager organisation is configured, every one of them is searched automatically — you don't need to know in advance which school or org a device belongs to.
3. Read the results
Each entry gets its own card: model, ship date, a status badge (Active/Expired/Unknown), the warranty end date, and a table of every coverage entry on file with its own start/end dates. An Apple result also shows which org it was found in. An entry with no data on file shows an explanation instead.
Settings
The gear icon (top right) opens Theme (System/Light/Dark), this Help guide, Release Notes, Leave Feedback, and — on browsers that support it (Chrome/Edge) — Install App, which adds a standalone, taskbar/home-screen-pinnable copy. Safari/iOS has no equivalent Install button, but Add to Home Screen from the Share sheet works there instead.
Your data
Nothing you search is stored. Each lookup is proxied through a Cloudflare Worker straight to the manufacturer's own API and back — no database, no logging, no analytics.
