A first-hand audit of open-source property management software, compiled by RapidEye Research in July 2026: 26 verified statistics covering how much of the ecosystem is abandoned, which platforms actually install today, the complete absence of a vacation rental operations platform, and where the real development activity lives. Unlike most statistics pages, nearly every figure here was produced by our own measurement: 1,125 GitHub repositories surveyed by API, 25 deployable platforms profiled, and 14 platforms installed (or failed) by hand in clean Docker environments, with the full audit table published below.

Key takeaways
The open-source property management ecosystem is large on GitHub and small in practice. Most of it is abandoned coursework and dead startups; the maintained core is a handful of hotel and long-term rental platforms; and for vacation rental operations specifically, there is nothing. When we stopped reading repositories and started installing them, only five of fourteen platforms worked as documented.
59% of open-source property management projects have not been touched in over a year.
Only 5 of 14 install-tested platforms worked by following their documentation alone.
No maintained open-source vacation rental operations platform exists.
QloApps has more stars than the other 24 audited platforms combined.
All 4 install failures were abandoned projects that no longer build.
47% of self-described open-source PMS repos have no standard license.
How we built this report
Every figure was produced or retrieved first-hand by RapidEye Research in July 2026; nothing here is aggregated from other statistics pages.
- Surveyed the ecosystem by API
39 GitHub search queries across property, hotel, hostel, vacation rental, and short-term rental terms returned 1,125 unique repositories, retrieved with stars, license, language, and commit dates on July 31, 2026.
- Profiled the deployable platforms
25 repositories that claim to be installable management software (not tutorials or coursework) got a deep pull: contributor counts, commit activity over the trailing 12 months, archive status, and branch structure.
- Install-tested 14 of them
Each was brought up in a clean Docker environment following its own documentation. Pass means we reached a working login screen or dashboard; we recorded every manual fix that was needed along the way.
- Independent review
Written by one co-founder, reviewed by the other before publishing, with the full per-platform results published in the audit table below.
Honest scope caveat: GitHub search is not exhaustive (projects hosted elsewhere, or described in other languages, can be missed), star counts measure attention rather than quality, and install tests reflect one competent attempt per platform on one day (July 31, 2026) on an ARM Mac, not every possible configuration. Individual results will vary with platform experience and hardware.
Open-source property management, by the numbers

The ecosystem in numbers
The ecosystem looks enormous until you filter it. According to RapidEye Research's July 2026 sweep of the GitHub search API, 39 queries across property, hotel, hostel, and rental terms return 1,125 unique repositories, of which 133 describe themselves as a property, hotel, or rental management system or software. Most of that 133 is inactive: 78 repositories (59%) have had no commit in over a year, 65 (49%) in over two years, and 63 (47%) publish no standard open-source license at all, which makes them legally unusable regardless of code quality. A large share of what remains is university coursework: database-class hotel management systems that were pushed once and never touched again.

Only about 25 repositories in the entire sweep are deployable management platforms rather than tutorials, clones, or coursework.
RapidEye Research manual triage (July 2026)
What this means: "Open source property management software" is a long list of dead links wearing a big number. The searchable ecosystem overstates the usable ecosystem by roughly 40 to 1, and license gaps disqualify almost half of what looks usable before you ever run the code.
The install test: what actually runs
Reading a repository tells you what a project claims; installing it tells you what it is. According to RapidEye Research's install testing, 10 of 14 platforms reached a working login screen or dashboard, but only 5 got there by following their documentation alone. The other 5 passes needed manual intervention: Movin' In's Docker Compose references environment files that exist only in its wiki, FewohBee needed two hand-edits to its environment file, OpenKos needed a port conflict resolved and a frontend build the quick-start does not mention, and QloApps, the most-starred platform in the category, ships no first-party Docker image at all, so we hand-rolled a LAMP stack before its six-step web installer could run. The failures were uniform: all 4 were projects last maintained between 2019 and 2023, and every single one died on dependency resolution, not application bugs.

What this means: Abandonment is not cosmetic. An open-source platform that stops shipping commits keeps looking installable for years while its dependency tree quietly rots underneath it; every dead project we tested failed the same way. Maintenance recency is the single best predictor of whether the install works.
The vacation rental gap
The single clearest finding in this audit: there is no maintained open-source vacation rental operations platform. The most active short-term rental open-source project on GitHub is not a platform at all; it is Rental Control, a Home Assistant calendar integration with 78 stars that turns iCal feeds into door-code automations. Second is StayView, a single-purpose iCal dashboard with 30 stars and one contributor. Every attempt at something bigger is dead: Superhost-Tools (2017, auto-messaging and pricing) crashes on the modern Express API and depended on an unofficial Airbnb API that no longer exists; LibreProperty ("Property Management SaaS focusing on vacation rentals") stopped in 2023 and no longer builds; and Cocorico, at 871 stars the largest STR-adjacent codebase ever open-sourced, went closed-source in 2021, its README redirecting to a commercial successor.
Statistic 15
Zero actively maintained open-source vacation rental operations platforms exist as of July 2026.

Statistic 20
No open-source project in the audit covers turnover operations, housekeeping scheduling, or inspection workflows for short-term rentals.
RapidEye Research (July 2026)
What this means: The operations layer of short-term rentals (turnovers, housekeeping, inspections, guest-stay workflows) has never had a serious open-source contender. What STR open source does exist reflects individual hosts automating their own homes, not operators running portfolios. Operators building custom internal tooling today are starting from a blank page, typically alongside their commercial systems rather than instead of them.
Where the activity actually is
Where open-source property software is genuinely alive, it clusters in two places: hotel reservations and long-term rent collection. According to GitHub repository data retrieved July 31, 2026, QloApps holds 14,173 stars, roughly 2.7 times the other 24 audited platforms combined, with 17 contributors and steady commits since 2015. The long-term rental side is broader: Microrealestate (1,155 stars) leads on attention but has slowed to 2 commits since August 2025, while Condo (387 stars, 50+ contributors) is the most collaboratively developed project in the audit. The Odoo Community Association's PMS shows the ecosystem's ceiling: its full property management module lives only on the Odoo 14 branch, a host version now years outside Odoo's three-version support window, while the current-version branch contains a single helper module. And 2026 brought a new pattern: AI-era entrants like HAIP, an Apache-2.0 hotel PMS created in April 2026 that advertises built-in AI agents and passed our install test on one command.

Statistic 25
Two archived platforms (Loca, 239 stars; ORPMS, 84 stars) were formally shut down by their maintainers rather than left to drift.
GitHub archive status (July 2026)
Statistic 26
Four of the audit's 25 platforms were created in 2026 (HAIP, OpenKos, StayView, and SyncZen), all AI-era codebases under 100 stars.
GitHub repository creation dates (July 2026)
What this means: Open source solved the booking engine and the rent ledger, the two most commodity layers of property software. The operational layers above them never attracted maintainers, and the projects now filling the vacuum are brand-new AI-era codebases whose staying power is unproven. Watch the 2026 cohort: they are small, but they are the first new activity this category has seen in years.

Quick FAQ
Is there an open source vacation rental management system?
No maintained one exists as of July 2026. In an audit of 1,125 GitHub repositories, RapidEye Research found zero actively maintained open-source vacation rental operations platforms. The most active short-term-rental open-source project is a Home Assistant calendar integration with 78 stars, followed by a single-purpose iCal dashboard with 30 stars. Every past attempt at a full STR platform (Superhost-Tools, LibreProperty, Cocorico) is abandoned and no longer builds.
What is the best open source hotel management system?
QloApps is the clear leader by adoption: 14,173 GitHub stars as of July 2026, more than the other 24 platforms in our audit combined, with over 100 commits in the last year. It also passed our install test, though it ships no first-party Docker image. HotelDruid is the longevity pick: version 3.0.8 ran from the official tarball in under 5 minutes with no database server. HAIP is the newest entrant, an Apache-2.0 hotel PMS created in 2026 whose one-command Docker install worked as claimed.
Why do abandoned open source property management projects fail to install?
Bit rot. All 4 install failures in RapidEye Research's 14-platform test were projects last maintained between 2019 and 2023, and every one failed on dependency resolution rather than application bugs: pinned packages that no longer build on current runtimes (LibreProperty's gevent), unpinned packages that resolved to incompatible modern versions (Superhost-Tools on Express), a Dockerfile whose npm install now hits a version conflict (Pesan PMS), and legacy tooling modern Composer refuses to run (Cocorico).
Is there an open source alternative to turnover operations platforms like Breezeway?
No. The open-source ecosystem clusters around reservations (hotel booking engines) and rent collection (landlord tools); we found no open-source platform covering professional turnover operations, housekeeping scheduling, or inspection workflows for short-term rentals. Operators who want custom workflows typically build small internal tools alongside their commercial operations platform, keeping the commercial system as the system of record.
