FoldTrail — Folding@home companion by ArjunP

Every fold has a story. FoldTrail helps you keep yours.

Folding@home shows your totals. FoldTrail saves observations over time so you can see what you've contributed between visits, work toward your next milestone, and notice when credited work goes quiet.

• Follow up to five donors, teams, or a donor's contribution within one team.
• See points and completed work units earned between observations, plus rank movement.
• Set points or work-unit milestones and receive a conditional estimate based on your observed pace.
• Keep milestone and quiet-period notes, with optional Firefox notifications.
• Check a compact toolbar summary or open the full contribution journal.
• Export JSON backups and CSV observations, restore a journal, or delete your local data.

Your history, settings, and goals stay on this device. There is no developer server, analytics, advertising, or cloud account.

After you enable the connection, selected donor names and IDs go directly to the public Folding@home API to retrieve statistics. No password or passkey is needed. You can pause collection at any time.


History begins when you add a profile. Collection runs while Firefox is open, every one, three, or six hours. Missing intervals are marked rather than turned into invented daily results.

Pace estimates need at least six hours of observations. A quiet-period note means no new credit was observed; it does not prove a Folding@home client failure.

FoldTrail is an independent companion and is not affiliated with or endorsed by Folding@home. It does not start, stop, or monitor live progress inside the Folding@home client.
