Where the crew talks
Channels for your line or shift, direct messages, threads and @mentions.
Talk shop. Keep it in-house.
Guildhall is team chat for crews that runs on your own server. Channels for each line and shift, direct messages and threads, on phones, plant tablets and desktop PCs.
Get in touchApps for iOS, Android, Windows and Linux. No per-seat fees.
For your crew
Talk to your crew, your shift and your supervisor in one place. Built for the floor, not the office.
Made for the floor
Big buttons that work with gloves, high contrast, and text that follows your phone's size setting.
No email needed
Sign in with a username your supervisor gives you.
Show, don't describe Planned
Take a photo of the problem and post it where the right people see it.
Shared tablets Planned
Pick your name, enter a PIN, and you are in. It signs you out at shift end.
For management, IT and security
Your people need to talk about the work, and the work is confidential. Your server. Your rules.
Self-hosted
It runs on your own server. Your messages are not in someone else's cloud. One deployment is one organization.
Compartmentalized
People see only the channels their groups are given. What they can do comes from one role each.
Approved devices only
An app can sign in only from a device an administrator has approved, and a device can be shut out at once.
Tamper-evident audit log
Every sign-in and every administrative change is recorded in a chain that shows if a record was altered or removed.
Instant offboarding
Disable a user and they are signed out everywhere at once.
Screen capture blocked
Screenshots and screen recording are blocked where the platform allows. That is Windows today, with Android and iOS in progress.
Photo control Planned
Each role gets a photo level, from "can post but not view" up to "unrestricted". Lower levels get resized, watermarked copies. Originals stay on the server.
Microsoft sign-in Planned
Microsoft sign-in for office staff, alongside plain usernames for plant staff.
What Guildhall does not do
Being exact about limits is part of the job.
- No video calls or screen sharing.
- No file attachments other than photos.
- No chat in a browser. The web console is for administrators only.
- No multi-tenant hosting.
- It is not end-to-end encrypted. The server holds the content, on your own hardware.
- Linux cannot block screen capture.
