Open-Source Hotel PMS: What You Get and What It Costs
QloApps and HotelDruid are genuinely free software with no licence cost at any size. Here is what you get, what you take on instead, and when a hosted free tier is the better decision.
What is the best open-source hotel PMS?
Two options are genuinely used in production: QloApps and HotelDruid. Both are free software with no licence cost at any property size. Both require you to run and maintain the server they sit on.
QloApps is an open-source hotel reservation system and website builder built on e-commerce foundations, with front-desk PMS features, multilingual support and direct website booking. Its source is public on GitHub. HotelDruid is web-based PHP property management software with interactive drag-and-drop calendars, automatic room assignment, seasonal rates, invoicing and an optional point-of-sale module.
The honest framing: open source is free in licence, not free in total. You supply the server, installation, backups, security patching, upgrades and troubleshooting — or you pay someone who can. For an operator with real technical capability that is often a good trade, because you get complete data ownership and no vendor dependency. For an operator without it, the hosting burden usually costs more in time and risk than a hosted subscription would.
What open source actually gives you
- No licence cost at any size. No room caps, no per-user fees, no upgrade pressure as you grow.
- Complete data ownership. Your reservations and guest records sit in a database you control, which matters for some data-residency and privacy requirements.
- No vendor dependency. The software cannot be discontinued, repriced or acquired out from under you. If the project stops, your installation keeps running.
- Full modifiability. With a developer, you can change anything.
What it costs you instead
- A server, and someone to run it. QloApps needs a PHP and MySQL environment on Apache or Nginx; HotelDruid needs a PHP host. Neither is exotic, but both need maintaining.
- Security patching, forever. A property management system holds guest personal data and payment context. An unpatched public-facing installation is a genuine liability, not a theoretical one.
- Backups you actually test. Untested backups are not backups, and nobody else is doing this for you.
- Upgrades and integration work. Channel manager, payment gateway and door-lock integrations are your problem to build, buy or do without.
- No support desk. Community forums rather than a phone number, at 11pm on a Saturday when check-in is broken.
Add it up honestly. If you are paying a developer even a few hours a month, the economics look very different from “free” — and should be compared against hosted free tiers that cost nothing and carry no maintenance burden at all.
Open source vs hosted free: how to decide
These are different products for different operators, and the choice is usually settled by one question: who maintains the server?
Choose open source if you have in-house technical capability or a reliable developer, if data residency or full data ownership is a hard requirement, or if you want to modify the software itself. Those are real reasons and no hosted product satisfies them.
Choose a hosted free tier if nobody on your team administers servers, if you want OTA channel management without building integrations, or if you would rather spend your time on the property than on patching. Hosted free options with no room cap now exist — FrontDesko's free tier includes the PMS, direct booking engine, guest app and point of sale with unlimited rooms, and Hoteliera publishes a free PMS core with unlimited rooms too. Both are compared on free PMS for small hotels.
A reasonable middle path some operators take: run open source if a technical founder or family member genuinely enjoys maintaining it, and move to hosted the moment that person's attention is needed elsewhere. The migration is easier in that direction than most people expect, because your data is already in a database you control.
What to check before committing to open source
- When was the last release? Check the GitHub repository or project site. An abandoned project is a security problem waiting to happen.
- Which channel managers integrate? OTA connectivity is the hardest part to build and the most likely gap.
- How is payment handled, and is it PCI-appropriate? Never improvise here.
- Who patches it, and how quickly? Name the actual person. If the answer is “we'll figure it out”, you have your answer.
- What is your restore procedure? Test it before go-live, not after an incident.
We are not an open-source product and have no stake in talking you out of one — if full data ownership is what you need, QloApps and HotelDruid are credible and we would rather you knew that than discovered it later. What we would push back on is choosing open source purely to avoid a subscription, when hosted free tiers with no room cap exist and carry none of the maintenance burden.
Questions
What is the best open-source hotel PMS?
QloApps and HotelDruid are the two genuinely used in production. QloApps is an open-source hotel reservation system and website builder built on e-commerce foundations, with front-desk features, multilingual support and direct website booking, and its source is public on GitHub. HotelDruid is web-based PHP software with drag-and-drop calendars, automatic room assignment, seasonal rates, invoicing and an optional point-of-sale module.
Is open-source hotel software really free?
The licence is free at any property size, with no room caps or per-user fees. The total cost is not zero: you supply the server, installation, backups, security patching, upgrades and troubleshooting, or you pay someone who can. If you are paying a developer even a few hours a month, compare that honestly against hosted free tiers that cost nothing and carry no maintenance burden.
What do I need to run an open-source hotel PMS?
A web server you control and someone who can administer it. QloApps needs a PHP and MySQL environment on Apache or Nginx; HotelDruid needs a PHP host. Beyond the initial install you need ongoing security patching, tested backups, upgrade handling, and someone reachable when something breaks outside office hours.
Open source or a hosted free PMS — which should I choose?
It usually comes down to who maintains the server. Choose open source if you have in-house technical capability, if data residency or full data ownership is a hard requirement, or if you want to modify the software. Choose a hosted free tier if nobody administers servers, if you want OTA channel management without building integrations, or if you would rather spend your time on the property.
Does open-source hotel software have a room limit?
No. There is no licence cap on rooms, users or properties, which is a genuine advantage over most hosted free tiers — Nobeds, for example, caps its free plan at 10 rooms. The practical limits come from the server you run it on rather than from the software. Note that some hosted free tiers also have no room cap, so this is not unique to open source.
What are the security risks of self-hosting a PMS?
A property management system holds guest personal data and sits next to payment flows, so an unpatched public-facing installation is a real liability rather than a theoretical one. You are responsible for applying security updates promptly, keeping the underlying server patched, configuring transport security correctly, and maintaining backups you have actually tested restoring.
Can open-source hotel software connect to Booking.com and Expedia?
Sometimes, and this is usually the hardest gap to close. OTA connectivity is the most complex part of a property management system to build and certify, so check which channel managers integrate with your chosen project before committing. If OTA synchronisation matters on day one, verify it specifically rather than assuming an integration exists.
How do I know an open-source project is still maintained?
Check the date of the last release and recent commit activity on the project repository or official site, and look at whether security issues get responses. An abandoned project does not stop working immediately, but it stops receiving security patches, which for software holding guest data is the point at which it becomes a liability rather than an asset.

Or skip the server entirely
If nobody on your team wants to patch a web server at 11pm, FrontDesko's hosted PMS, booking engine, guest app and POS are free at unlimited rooms with no maintenance burden.
