A station disconnects
Its local app may close, the PC may restart, or its network link may drop.
How it works
How Station Chat keeps your team connected.
Local-first messaging connects trusted stations directly, keeps working through individual PC outages, and restores recent conversation context when a station returns.

The core idea
Each Windows PC is an independent station.
Trusted stations communicate directly across the permitted network. There is no separate office chat server that every conversation depends on.

Offline recovery
One station can disconnect without stopping the team.
Other stations continue
Connected stations keep exchanging messages directly; there is no central host to lose.
The station catches up
When it reconnects, retained recent group messages are merged and deduplicated.
Direct messages wait for delivery
If the recipient's station is offline, the sender keeps the message queued and retries after reconnection. Delivery is completed and acknowledged instead of silently disappearing.

Group chat restores recent context
A returning station requests retained recent group history, merges what it missed, and removes duplicates. This is bounded recovery—not a claim of unlimited history—and attachment bytes are not replicated as group-history payloads.
Network layout
Automatic nearby discovery, controlled routed access.
Same subnet
Stations discover each other automatically, then complete the required trust and approval checks before joining the organization mesh.
Different subnet or VLAN
An administrator connects by IP address or hostname. Existing routing, firewall rules, and access-control policy must permit the connection.
Stable Mobile
An authorized iPhone or Android device pairs with a specific station. It can reach chat from local or mobile networks and receive supported push notifications. Internet access is required for push delivery and relay-related functions.
Network Readiness
A diagnostic check helps identify the listener, address or DNS resolution, TCP 47892 reachability, and best-effort firewall state, then explains the likely cause in plain language.

Frequently asked
Deployment questions, answered.
What is a local-first team messenger?
A local-first team messenger keeps core conversation traffic on the permitted organization network instead of routing every message through a central cloud chat server.
Does Station Chat require user accounts?
No individual cloud account is required for core station messaging. Devices and stations use their approved identities and pairing relationships.
Can Station Chat work without internet?
Core messaging between reachable stations works over the local or permitted routed network. Internet is used for functions such as licensing, updates, Stable Mobile location and push delivery.
Can Station Chat work across different subnets?
Yes, when an administrator connects by IP address or hostname and the network permits traffic between the subnets.
What happens when a Station Chat PC goes offline?
Other stations continue. A returning station catches up on retained recent group history, while queued direct messages retry delivery.
How does Stable Mobile work?
A phone installs the web app, pairs with one authorized station, and can receive supported push notifications and reconnect as its network address changes.
Do all Station Chat PCs have to be on the same network?
No. Stations on the same subnet discover each other automatically. Stations on routed network segments can be connected directly by IP address or hostname, as long as the network allows Station Chat's traffic between them.
What if two stations can't see each other?
Use the built-in Network Readiness Test. Station Chat checks the local mesh service, station address resolution and TCP connectivity, then gives a plain-language explanation of what may be blocking the connection — instead of just "connection failed." It diagnoses the connection without changing your router or network security settings.
Will I lose messages if a station is temporarily offline?
Direct messages are queued for a recipient's offline station and delivered once it reconnects. Stations also exchange any group messages they missed after reconnecting, so a temporary outage doesn't leave a permanent gap in normal conversation history.
What happens if one PC goes offline?
The other stations keep communicating. When the offline station reconnects, it automatically catches up on the group messages it missed. Direct messages waiting for someone on that station are delivered once it's back.
Does Station Chat send every group message as a phone notification?
No. Ordinary group conversation stays quiet by default. The sender of a message can use the one-time Bell when that specific message needs everyone's attention. Private-message notifications remain targeted to their intended recipient.
What happens if someone loses or replaces their phone?
A saved identity backup restores their same name, encryption credentials and access to their private-message history on the new device.
Can I remove a device?
Yes — an administrator can block a device at any time, which also revokes its notification access.
Can we use our own company name and logo?
Yes. Set it once on any station and it syncs automatically to every other station and phone.
