The published facts, in plain English
Seam is Smart-lock developer API. It lists its pricing as Free dev tier; $5/device/mo → $50/device/mo. There is a free tier. It runs without a separate PMS. Scale: mid.
Data-desk note: The plumbing under other apps; not a host-facing product.
Who it’s for
This service is for property managers and developers building their own systems or integrating smart locks into existing platforms. It is not directly for individual hosts.
Our take
Seam provides a free tier for development, with paid plans ranging from $5 to $50 per device per month. While it doesn't require a Property Management System (PMS), its "Data-desk note" indicates it functions as the technical plumbing rather than a host-facing product. It is a mid-sized player in this specific niche.
How it compares to BnBGenius
Side by side on published terms: Seam lists Free dev tier; $5/device/mo → $50/device/mo, while BnBGenius lists free for the first 500 messages, then $10/month flat, with no PMS required. Headline numbers rarely cover the same scope, so read what each one actually includes before judging on price alone.
Verdict
Seam's API is a robust tool for system builders, but individual hosts seeking an all-in-one solution might prefer an owner-first alternative like BnBGenius.

What to pin down with Seam
- “Is Free dev tier; $5/device/mo → $50/device/mo per listing or flat?” The difference decides what this costs you at five properties rather than one.
- Free tier or trial. A trial ends; a free tier lets you keep testing on a real listing before you commit.
- What it needs underneath. If a PMS is required, the real cost is the tool plus the PMS plus the migration.
