Best open source software for real estate
For a real estate agency, a self-hosted stack starts with Twenty for clients and deals, Docuseal for signing contracts and Cal.diy for booking viewings.
The catalog has no dedicated property-management or MLS app, so this page builds a real estate stack from general tools: a CRM for clients and deals, e-signatures for contracts, booking for viewings, a website for listings and document storage.

Is there an open source real estate CRM?
Not a dedicated one in this catalog. General CRMs such as Twenty, EspoCRM and Krayin handle contacts, deals and pipelines, and you can add custom fields for properties.
Are self-hosted e-signatures legally binding?
DocuSeal, Documenso and OpenSign create and sign digital documents. Whether an electronic signature is binding depends on your country and the type of contract, so check local rules; this is not legal advice.
Is Twenty free?
Yes. Twenty is open-source software released under the AGPL-3.0 license, so you can self-host it at no cost. You only pay for the server it runs on, and some projects also offer an optional paid cloud plan.
Can I run this stack with Docker?
9 of the 15 apps here publish Docker images, including Twenty, EspoCRM and Krayin, so most of the stack can run side by side with Docker Compose on one server. Size the server for the heaviest app and add off-site backups.
