Home Assistant vs Gladys Assistant

An honest comparison between two open-source home assistants

Still hesitating between Home Assistant and Gladys Assistant? This comparison will save you hours.

Full transparency: I'm Pierre-Gilles, the creator of Gladys Assistant, so I'm obviously biased. But I'll be fair about both projects. Here's how they really compare, and why I believe Gladys is the better fit for most people who want a smart home that simply works.

Both projects started in 2013, right after the first Raspberry Pi came out. They look similar at first glance, but they're built on very different philosophies, and that difference is exactly what should guide your choice.

The short version

Choose Gladys Assistant if…

  • You want something simple, fast to set up, and that just works.
  • You prefer a clean interface where everything happens with clicks, with no configuration files and no YAML.
  • You value stability: updates are fully automatic and atomic.
  • You want a responsive project where your feedback actually shapes the product.

Choose Home Assistant if…

  • You own very specific or niche devices that need a dedicated integration.
  • You're a power user who loves to tinker and customize to the extreme.
  • You're comfortable editing YAML and going under the hood.
  • You want the largest possible catalog of integrations, even if quality varies.

Installation

Gladys Assistant

Gladys is genuinely simple to install. It runs with a single Docker command (a `docker run` line or a `docker-compose` file you copy, paste and launch), and the documentation walks you through every step with screenshots and installation videos.

If you'd rather skip setup entirely, the official starter kit is a Beelink mini-PC that arrives with Gladys already installed and configured. You plug it in, follow the quick-start guide, and you're up and running in minutes.

And because Gladys is just a container, you stay free to use your mini-PC, NAS or Raspberry Pi for other things too.

Home Assistant

Home Assistant offers Home Assistant OS, which is polished, and the Home Assistant Green box arrives ready to use.

It's straightforward if you buy their box. Without it, though, it's not always obvious which installation method is the simplest, since they tend to push Home Assistant OS over the plain Docker route.

The verdictBoth are beginner-friendly if you buy their hardware. But Gladys is especially easy to install yourself, thanks to a one-line Docker setup, rich documentation and step-by-step videos.

Interface & ease of use

Gladys Assistant

Gladys has a clean, intuitive interface. The whole philosophy is to think about the user before the technical implementation: you never have to dig into logs or edit a file on disk. Everything happens with the mouse.

You can build as many dashboards as you want, one per room or by theme (energy, security, and so on), with no configuration files because there simply aren't any.

Gladys deliberately keeps things focused: you arrange the widgets you actually need instead of wading through endless options. And since it's open-source, anything missing can be added by the community.

Home Assistant

Home Assistant has a modern Material Design interface that's clean and highly customizable. The dashboard is fully editable with tons of cards and options.

But you'll often see, on the forums, that some parts still require editing YAML files, which can be intimidating for a beginner.

The verdictFor a beautiful experience that works out of the box, Gladys is hard to beat. Home Assistant gives you more knobs if you enjoy customizing every last detail.

Integrations & compatibility

Gladys Assistant

Gladys focuses on what matters: a curated set of integrations built around open standards like Zigbee, Matter and MQTT. Each one is carefully built and tested end to end, designed like a polished consumer product rather than by developers for developers.

Through Zigbee and Matter alone, that already means thousands of compatible devices. The bet is that open standards, Matter especially, will dominate, so Gladys invests heavily where the market is heading, not in closed, cloud-only ecosystems that lock you in.

For anything not natively supported yet, Matterbridge can bridge devices onto a Matter network, including a Home Assistant plugin.

Home Assistant

Home Assistant has a massive catalog with thousands of community integrations, so even niche devices are often supported out of the box.

The flip side is variable quality: some integrations are excellent, others less so, and it's up to you to find the right one and test that it works.

The verdictIf you value integrations that just work and are built to last, Gladys' curated approach is hard to beat. If you own very niche hardware and enjoy testing community add-ons, Home Assistant's sheer catalog is appealing. As the whole industry adopts Matter, the gap keeps shrinking.

Automations & scenes

Gladys Assistant

Everything lives in a single "Scenes" tab. A scene can be a manual sequence of actions you trigger from your dashboard, or a full automation with triggers, conditions and actions.

The visual editor is intuitive: you start with a trigger (optional), then chain as many conditions and actions as you want, and you can mix them freely, with a condition leading to actions, then more conditions. It's surprisingly powerful while staying easy to read.

And if you ever need to go further, you can offload complex logic to Node-RED and connect it to Gladys over MQTT or HTTP.

Home Assistant

Home Assistant has a visual editor too, plus shareable YAML blueprints and a Node-RED integration to go further.

It splits things into four tabs (Automations, Scenes, Scripts and Blueprints), which can feel like four versions of the same thing when you're starting out and adds to the learning curve.

The verdictGladys keeps everything in one simple, powerful place, while Home Assistant spreads it across four tabs. For most people, Gladys' single Scenes tab is faster to learn and just as capable for everyday automations.

Community & support

Gladys Assistant

Gladys is a project that genuinely listens. There's an active community on the forum, and a roadmap shaped by real user feedback rather than by what's easiest to build.

Best of all, you get direct support from the founder. If you have a question, even a deep one about the code, you can email me, post on the forum, or reach out on social media, and you'll get a personal answer. That kind of access is rare.

Home Assistant

Home Assistant has a huge global community and a massive forum, so you'll usually find someone who has already solved your problem.

With that scale, though, support is community-driven rather than personal, and most of the developer communication happens in English.

The verdictHome Assistant wins on sheer size. But Gladys offers something rarer: a responsive project where the maker listens and answers you personally.

Pricing & business model

Gladys Assistant

Gladys is 100% free and open-source at its core, forever. There's an optional Gladys Plus subscription for remote access, encrypted automated backups, voice assistants (Google Home, Alexa), AI and Enedis energy data.

I also sell starter kits, not to make margin but to make Gladys more accessible. The business model is really the subscription, with no investors, no ads and no data resale.

Home Assistant

Home Assistant is also 100% free and open-source at its core, with an optional Nabu Casa Cloud subscription (remote access, voice) and a growing line of hardware like the HA Green box.

The verdictBoth have a transparent, very similar model: a free open-source core plus an optional subscription. Either way, you're funding an independent project rather than a data-hungry tech giant.

Why not both?

Here's the part most comparisons miss: you don't have to choose. You can run Gladys Assistant and Home Assistant on the same setup at the same time.

With Zigbee2MQTT, a single Zigbee instance can talk to both Gladys and Home Assistant, so the same device shows up in both interfaces. The same goes for Matter: a device paired to a hub (like an Apple TV) can be controlled from both. You can have several controllers at once.

You can even use Matterbridge to expose all your Home Assistant devices onto a Matter network, then pull them into Gladys, effectively using Home Assistant as a backend and Gladys as your interface. And of course both expose rich APIs, so they can talk over MQTT or HTTP.

So if you love the Gladys interface but need a niche Home Assistant integration, run them side by side. There's really no excuse: everything is possible.
