Smart homes, connected offices, and intelligent devices – they’re all part of our daily lives now. And in 2025, open-source IoT platforms are making it easier than ever to bring automation to everything around us. Some platforms have really stepped up their game this year, so we’ve rounded up the top 5 you should definitely check out.
1st Place: Home Assistant
GitHub: https://github.com/home-assistant/core

Why It’s #1 in 2025
Home Assistant continues to be the gold standard for home automation thanks to its AI-powered automation, seamless integrations, and strong community. Its 2025 innovations make smart home control easier, more intuitive, and more sustainable.
2025 Highlights
- Blueprint AI 2.0: This powerful natural language tool allows users to write automation scenarios like “Turn on the heater when it’s below 65°F and someone is home,” without any coding. It uses local AI processing for faster and more private execution.
- Energy Dashboard v3: This major update introduces solar production forecasting based on local weather, battery management, and dynamic energy optimization. Great for households with solar panels or battery storage.
- Zigbee2MQTT Core Integration: Previously a separate project, this integration removes extra steps and makes it easier for users to connect Zigbee devices like sensors, lights, and thermostats with just one click.
2nd Place: OpenHAB
GitHub: https://github.com/openhab/openhab-core
License: Eclipse Public License 2.0
Why It’s #2 in 2025
OpenHAB has always been popular among professionals and advanced users. In 2025, it becomes much more accessible while staying true to its modular and scalable architecture.
2025 Highlights
- FlowBuilder UI: Inspired by Node-RED, this drag-and-drop editor allows users to create complex automations visually without writing rules in code. It’s now built into OpenHAB and supports triggers, conditions, and multi-device logic flows.
- EdgeLink Runtime: Designed for edge computing, this lightweight runtime reduces CPU and memory usage by up to 30%, making it ideal for small devices like Raspberry Pi Zero or smart gateways in industrial settings.
- Voice Assistant Integration: Native support for WhisperCPP (fast local speech-to-text) and Rhasspy (open-source voice assistant) offers offline voice control without Google or Alexa, giving users more privacy.
3rd Place: Node-RED
GitHub: https://github.com/node-red/node-red
License: Apache License 2.0
Why It’s #3 in 2025
Node-RED is the favorite among developers and technical users. While it’s not a full automation suite, it shines as a logic and flow builder. In 2025, Node-RED becomes more collaborative and IoT-ready.
2025 Highlights
- Real-Time Multi-User Editing: Teams can now work on automation flows together at the same time with live updates. Great for collaborative projects and educational uses.
- IoT Plugin Pack 2025: This pack includes pre-configured nodes for Matter, LoRaWAN, OPC-UA, and Bluetooth LE, enabling faster prototyping across a wide range of devices and protocols.
- Debug Mode 2.0: Enhanced debugging lets you trace data through each node, view real-time input/output logs, and easily isolate issues in complex flows — speeding up development dramatically.
4th Place: Gladys Assistant
GitHub: https://github.com/GladysAssistant/Gladys
License: MIT License
Why It’s #4 in 2025
Gladys Assistant continues to win the hearts of privacy-conscious users. Fully local, it doesn’t depend on any cloud service. In 2025, it has become faster, more compatible, and even easier to deploy.
2025 Highlights
- Matter Support: Gladys now supports Matter devices natively, allowing users to control smart lights, locks, thermostats, and sensors that are certified by Apple, Google, Amazon, and others.
- Performance Update v5: Rewritten parts of the backend make the platform twice as fast, with reduced load times and lower memory usage — especially helpful for those running Gladys on Raspberry Pi.
- Containerized Setup with Gladys+: New Docker images are optimized for Synology NAS and Home Server deployments, making it easy to get up and running in a few clicks.
🏅 5th Place: Domoticz
GitHub: https://github.com/domoticz/domoticz
License: GNU GPL v3
Why It’s #5 in 2025
Domoticz may not be flashy, but it’s very lightweight, stable, and still actively maintained. It’s a go-to solution for setups running on older hardware or for simple automation needs.
2025 Highlights
- Sensor Pack Integration: Domoticz now works out-of-the-box with Shelly Plus and Sonoff Zigbee devices. Setup is fast and friendly, with fewer configuration files needed.
- Mobile UI Refresh: While minimal, the new mobile interface is more responsive and touch-friendly, improving the experience for users on tablets or smartphones.
- Community Scripts Hub: Domoticz introduced an official platform for sharing and downloading ready-to-use automation scripts, which simplifies setup for common use cases like temperature control, lighting scenes, or motion-triggered events.
