See the whole picture of the public Signal ecosystem.
Search profiles, map group networks, and trace how identities change over time — every record timestamped and sourced. Signal Users turns scattered public activity into a structured picture your team can work from.
600K+ profiles · 7,000+ groups · refreshed every 48 hours
One workspace for the whole Signal picture.
Start with a name, a Service ID, or a group. Signal Users gives you the profile, the history, and the network around it — organized, sourced, and ready to export.
Fast Profile Search
Search 600K+ profiles by name, Service ID, or keyword, then filter by admin status, avatar, or group count. Results land in seconds.
Identity History
See how a profile changed over time — name, description, and avatar updates captured in timestamped snapshots, so you always know what was true and when.
Group Presence & Networks
Map which groups a profile belongs to, spot admin and moderator roles, and see the cross-group connections that reveal how communities overlap.
Avatar Library
Every profile's avatar is preserved for review. Where an avatar shows a person, it can be run through your own facial-recognition tools for verification.
Technical Identifiers
Service IDs on every tracked profile plug straight into Signal CLI workflows. Phone numbers are surfaced where available (roughly 0.5% of profiles).
Export & Report
Take a clean copy with you — export profiles, group memberships, and history to PDF, JSON, or CSV for your case file or downstream tools.
Watch an identity evolve — snapshot by snapshot.
Usernames change, descriptions get rewritten, avatars swap out. Signal Users keeps every version on a single timeline, so a profile's past is never lost to an edit.
- Timestamped snapshots for consistent, reliable tracking
- Name, description, and avatar changes surfaced side by side
- Group joins and departures flagged as they happen
- Fresh data every 48 hours, going back across the record
From a single lead to a full profile.
Four steps, no data wrangling. Everything you surface carries the snapshot and timestamp it came from.
Search
Enter a name, Service ID, keyword, or group. Filter the results down to exactly what matters.
Explore

Trace
Step back through the history timeline to see how the identity and its group presence changed.
Export
Save a sourced, timestamped copy to PDF, JSON, or CSV for your case file or reporting.
