Why xpriments

Science, finally version-controlled

Everything you need to document, share, and reproduce experiments - structured, searchable, and open (or private).

Publish & share

Upload your experiment in .xpr format. Set visibility to public, org-only, or private. Every experiment gets a permanent URL.

Discover & reproduce

Search across experiments, protocols, organisms, and tags. Fork any public experiment to your own org with one click.

Version history

Every save is a snapshot. Restore any previous version, compare changes, and track the evolution of your protocol.

Security
Security & privacy

Your research,
on your terms

Every experiment has granular visibility controls — public for open science, org-only for internal collaboration, or private with link-sharing for peer review before publication. You decide who sees what, always.

  • End-to-end access control per experiment
  • Private sharing via secure link tokens
  • Org-scoped visibility for internal work
  • Audit trail via full version history
Collaboration

Science moves
faster together

Invite your lab, share with your organization, or publish openly. Fork any protocol and build on it — every experiment keeps a permanent link back to its origin.

  • Org-level sharing — your whole lab sees it instantly
  • Fork any public experiment with one click
  • Every fork traces back to the original author
  • Private link sharing for peer review before publication
  • Granular roles per collaborator — Viewer, Reviewer, Editor, or Admin
Open standard

Structured experiments,
not just PDFs

The .xpr format encodes your hypothesis, protocol, materials, observations, and analysis into a single machine-readable file — making experiments searchable, forkable, and reproducible.
