Frontstead Kit is an open-source development kit for building branded real-estate portals, including sites for golf, waterfront, and other niche lifestyle markets. Its parts include a Next.js public portal, an Express 5 and Prisma REST API, and a separate worker that synchronizes data through the RESO Web API. The portal supports property search, listing pages, inquiries, consumer accounts, and favorites. The connector lists MLS Grid, Trestle, Bridge Interactive, and Spark API as supported vendors. Typesense can provide typo-tolerant search; without it, the kit uses PostgreSQL search. It requires Node.js 22.12 and PostgreSQL, while Redis and Typesense are optional. Docker Compose is the documented portable deployment baseline, and the project does not assume a specific platform. MLS display controls are off by default, and configuration stops if a board is unregistered. The agent API is disabled by default. The self-hosted kit is free at no cost; Agent HQ, which adds CRM features, is separately licensed.
Who it is for
It suits developers and agencies building portals for brokerages or niche real-estate markets. Teams wanting Agent HQ’s CRM features should note that it is separately licensed.
