Under the hood

How Real-Time Desk Availability Works

Unlike polling-based systems that refresh every 30 seconds, Administo pushes changes to every connected user in under 50 milliseconds.

Phoenix LiveView

Server-rendered HTML pushed over WebSockets. No JavaScript framework needed. Changes are diffed and patched — only changed parts update.

PubSub Broadcasting

When a booking is created, cancelled, or checked in, Phoenix PubSub instantly notifies every user viewing that floor. Zero polling, zero manual refresh.

Visual Floor Grid

Desks and rooms rendered on an interactive CSS grid matching your physical floor. Color-coded status: green (available), red (booked), yellow (partial).

Conflict prevention

Database-Level Double Booking Prevention

Most coworking software checks for conflicts in application code — which fails under concurrent requests. Administo does it differently.

Traditional Approach

  • Application checks for overlap before insert
  • Concurrent requests can pass the check simultaneously
  • Race conditions cause double bookings
  • Requires pessimistic locking or retry logic

Administo's Approach

  • PostgreSQL EXCLUDE constraint with time ranges
  • Database itself rejects overlapping bookings
  • Works perfectly under any concurrent load
  • Zero race conditions — mathematically impossible
The constraint that prevents all overlaps
ALTER TABLE bookings
ADD CONSTRAINT bookings_no_overlap
EXCLUDE USING gist (
resource_id WITH =,
tsrange(start_time, end_time) WITH &&
)
WHERE (status != 'cancelled');
This single PostgreSQL constraint guarantees that no two active bookings for the same resource can have overlapping time ranges — at the database engine level.
