OpenApp vs Seam for physical access integration
Seam is often described as middleware for smart locks — one API across many lock brands. OpenApp is Physical Security as a Service (PSaaS): a full control plane for doors, gates, virtual intercom, guest invitations, policies, and audit across heterogeneous hardware.
This page helps integrators and STR operators choose — especially when hardware goes beyond commercial Wi-Fi locks (gates, relays, local automation — see the integrations catalog).
When Seam fits
Section titled “When Seam fits”- Primary hardware is lock brands on Seam’s supported list
- You need normalized lock tokens and a hosted Connect Webview for guests
- You will build your own dashboard, policies, intercom, and audit on top of Seam
- Single-vendor lock rollout across many identical units
When OpenApp fits
Section titled “When OpenApp fits”| Need | Why OpenApp |
|---|---|
| Non-lock openers and protocols | Integrations — not lock-brand adapters only |
| Time-bound guest invites | Native portal + invite APIs |
| Virtual intercom + directory | Virtual Access — no separate intercom vendor |
| Multi-site org + roles + audit | Operator dashboard, audit API, exports, and webhooks |
| One platform for gates + doors | Entity actions (switchable.open) across vendors |
Trade-offs
Section titled “Trade-offs”- Seam — faster if locks are on their adapter list; you still own product UX and compliance workflows.
- OpenApp — broader physical-access model; best when relays, gates, and intercom matter as much as room locks.

Section titled “Audit note”OpenApp records every door action in its audit log. Review it in the dashboard, pull it with the audit events API, export any date range, or stream it to your endpoint with HMAC-signed webhooks. See Query access and audit activity.
