Unified access platform vs split stack (Salto + ButterflyMX, Seam + custom dashboard)
Operators often assemble best-of-breed stacks:
- Hotel: Salto or Brivo for room keys + ButterflyMX for lobby intercom
- STR: Seam for lock API + custom Node/Python backend + Home Assistant for relays
- Apartment: Latch for units + separate gate vendor
OpenApp offers a unified Physical Security as a Service (PSaaS) layer when you want one org model, one invite system, one intercom surface, and one API across heterogeneous openers.
Split stack — when it makes sense
Section titled “Split stack — when it makes sense”- Each vendor is already contracted and sunk-cost
- Teams exist to maintain custom middleware indefinitely
- Requirements map cleanly to single-purpose SKUs (locks-only, intercom-only)
Unified OpenApp — when it makes sense
Section titled “Unified OpenApp — when it makes sense”| Requirement | Single platform benefit |
|---|---|
| Mixed openers in one portfolio | One integration engine |
| Guest invites + intercom + unlock | Virtual Access + public portal |
| Multi-site operator dashboard | Orgs, roles, audit review |
| API for prop-tech / PMS | SDK + OpenAPI + scripting |
| Avoid second intercom contract | vs ButterflyMX |
Architecture contrast
Section titled “Architecture contrast”Split stack (hotel example): PMS → Salto (room keys) PMS → custom glue → ButterflyMX (lobby) Gate vendor → separate controller
Unified OpenApp: PMS → your middleware → OpenApp (invites, directory, policies) OpenApp → integrations you deploy (as in catalog)OpenApp does not eliminate all glue — your PMS still sends webhooks to your service, which calls OpenApp. It eliminates parallel intercom + access products when Virtual Access covers lobby and guest flows.
