Peptide Relay status

Public Alpha

v0.9.0

Building Relay with the community.

Relay is now feature-complete and has entered its first Public Alpha.

From this point forward, improvements are driven by real-world usage, community feedback, analytics, and research rather than internal feature planning.

Thank you for helping shape Relay.

Public Alpha

The first feature-complete public release candidate for Peptide Relay.

Released July 2026

Last updated July 2026 · Updated with every public release.

Compound library

Start simple. Go deeper when you want.

Every profile uses the same structure: what it is, what humans have demonstrated, what is only preclinical, and what remains unknown.
