HappyCo scores C on Supergood's API Report Card. HappyCo publishes a gRPC Happy API with proto files and generated clients for inspections, reports and assets. Credentials are a client id and secret issued by HappyCo to enterprise customers or accepted plugin partners; there is no self-serve key, sandbox or maintenance API.
HappyCo 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. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
HappyCo is a multifamily operations platform built around unit-level inspection data.
Real Estate & Property; multifamily owners, operators and third-party managers, plus lenders and due diligence teams. Onsite teams run move-in, move-out, quarterly and safety inspections on phones and tablets with photo capture and signatures, then finalize reports on the web.
HappyCo cites more than six million multifamily units on its platform in 2026 press, up from nearly four million in 2024, and its inspection app is bundled inside Buildium and other property management systems.
Unit-level condition data, hundreds of millions of tagged photos, inspection reports with resident signatures, work orders and turn schedules, technician assignments, asset inventories, resident contact details used for maintenance notifications, and lending due diligence inspections tied to Freddie Mac Optigo transactions.

A ResMan user wished the two-way communication with the PMS happened faster. Reviewers report sync failures that lose inspection work and too many differences between the mobile app and the website. Full sourced list under Sources below.
Common alternatives include RentCheck, zInspector, SnapInspect, Property Meld, Latchel. Graded alternatives appear under "More from the report card" below.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Not that we could find. There is no official HappyCo MCP server in any public registry, and no maintained community server we're aware of. We re-verify this periodically — report an inaccuracy below if we missed one.
Not natively. HappyCo doesn't publish an MCP server, so MCP clients like Claude, Cursor, and Codex have nothing to connect to out of the box. If that changes, this page will reflect it.
