AppFolio

AppFolio is a Santa Barbara, California cloud-based real estate technology company providing property management software to residential, commercial, community association (HOA), student housing, single-family, and affordable housing operators, plus investment management tooling for sponsors and funds. Its flagship AppFolio Performance Platform unifies workflow automation, accounting and reporting, marketing and leasing, maintenance, resident communication, and resident services on a single multi-tenant SaaS. AppFolio embeds Realm-X, an in-house agentic AI layer (Realm-X Assistant, Performers, Flows) directly into the platform rather than as an add-on. Integrations are delivered through the AppFolio Stack marketplace, where certified partners (ButterflyMX, Conservice, HappyCo, Knock, Lowe's, Property Meld, and many more) connect via the AppFolio Stack API. The Stack API is gated behind a partner application, security-compliance questionnaire, and terms-of-service signing; OAuth 2.0, a sandbox environment, webhooks, and an OpenAPI/Swagger reference are made available only to approved partners through the developer.appfolio.com portal, so no public specification is reachable for catalog inclusion. AppFolio's revenue model is per-unit SaaS subscription plus value-added services (payments, screening, insurance, marketing). The AppFolio GitHub organization publishes internal Ruby on Rails, React, and tooling libraries (react-gears, ae_page_objects, store_base_sti_class) but no public API SDK, CLI, or OpenAPI artifact.

AppFolio is profiled on the APIs.io network. Tagged areas include Property Management, Real-Estate, Residential, Commercial, and Community Associations.

AppFolio’s developer surface includes Stack Overflow tag, GitHub presence, engineering blog, pricing, YouTube channel, and 21 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Education & Research regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/appfolio: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
