LimsRat — the lab tracker you can just open
Local-first sample tracking. No login, no server of record, free core. The lab keeps the data.

Split a sample in LimsRat and each aliquot links back to its source, and forward again if it's split a second time. The lineage stays on the record, so "where did this come from?" has an answer.

Scan from any phone. LimsRat does camera QR and barcode scan-to-find and scan-to-log right in the phone's browser, with no app to install. It's tested on iPhone Safari. Print QR labels and the bench and the record stay in step.

If a hosted tool shuts down, your data can go with it. In LimsRat, each sample can mirror to its own plain JSON file in a folder you pick, plus CSV export and full zip backup. If we vanish, your files still open.

Where is that tube? LimsRat keeps a storage location on every sample, from a managed location list or a plain-text position, and shows it all on a freezer map. Expiration badges and banners flag what's about to lapse before it's a surprise.

LimsRat has no account to create. There's no username, password, or session anywhere, including sync. Devices pair by QR code and talk directly over WebRTC; the relay only brokers the introduction and never sees your lab data.
