Seam is Smart-lock developer API. Published pricing: 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
Seam is one host software tool we track for owners weighing their options in North Carolina.
Our take
We list Seam’s own published details below; where a figure is not published, we say so rather than guess.
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.
What the published record signals
Category first: Seam is Smart-lock developer API, so judge it against that job — not against suites that promise everything. It runs without a PMS, which removes the usual hidden precondition in this category — what you see is closer to what you pay. Test path: the free tier on a single listing, through at least one busy weekend. On cost, the published Free dev tier; $5/device/mo → $50/device/mo is the number to hold against your own hours saved.
How this plays for two kinds of owner
- The remote self-manager. Automation earns its keep fastest at a distance — every task Seam genuinely takes over is a drive you do not make. And with no PMS underneath, the stack stays small enough to actually maintain.
- The small-portfolio host. Two or three listings is where per-listing pricing starts to bite and flat pricing starts to win — read Seam’s model with your exact count in mind.
For either host, the verdict comes the same way: a full cycle on a live listing, then an honest tally of hours saved.
Our advice before any contract: hold it against a benchmark — from your phone — the no-PMS, flat-price setup (free first 500 messages, then $10/month) we measure host tools against. If Seam beats that on the things you care about, you have your answer. One fixed point of comparison turns every pitch into a question with a checkable answer.
Verdict
A solid option to compare — but for an owner-first alternative we would start with 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.
Alternatives worth comparing
If you are drawing up a shortlist, these are the closest comparisons we would put beside it — each with its own published price, or a note that there isn’t one:
- Escapia — Not published (demo).
- OnCallClerk — Free tier; $29–$299/mo (overage applies).
- iGMS — FLEX $1/booked night (min $20/prop); PRO $18–$21/prop/mo.
Our own number one in this category is BnBGenius — see full-service STR management for how the no-PMS setup actually works.
