It is self-serve for property managers, but Marketplace and OTA partners are barred and routed to commercial approval. OAuth tokens are capped at 5 per key per 24 hours.
Guesty has an official API, but teams routinely hit its limits: gated access, partial coverage, or paid tiers. Most end up supplementing it with exports or an unofficial API layer like Supergood.
Guesty is the leading AI-powered property management platform (PMS) for short-term rental and vacation rental operators.
Vertical: Property Management, specifically Short-Term Rental (STR) / Vacation Rental PMS. Property managers running 10-500 short-term rentals use Guesty as their single back-office workspace: importing listings from Airbnb/Vrbo/Booking.com, syncing calendars across channels, accepting and triaging reservations, communicating with guests via a unified inbox (with AI-drafted replies), automating check-in instructions and door codes, scheduling cleaners between turnovers, processing damage deposits and incidentals, and generating owner statements.
High within its vertical. Guesty is consistently named in the top three vacation-rental PMS platforms globally alongside Hostaway and Hospitable (formerly Smartbnb), and is the largest by named enterprise logos and total listings under management.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial Guesty API and MCP server so AI agents and internal tools can read and write Guesty data. See the Guesty integration docs at supergood.ai/docs/guesty-api.
