If you intend to use Anjay Lite in any commercial context, you must fill in a registration form to obtain a free commercial license for your product.
Register here.
Why is registration required?
We introduced registration to:
- Gain insight into usage patterns – so we can prioritize support, features, and enhancements relevant to real-world use cases.
- Engage with users – allow us to notify you about important updates, security advisories, or licensing changes.
- Offer tailored commercial plugins, professional services, and technical support to accelerate your product development.
For inquiries, please contact: sales@avsystem.com
This is a beta release of Anjay Lite and is currently under active development. While we are making every effort to keep the API stable, changes may still occur as we refine the library based on testing and user input.
We encourage you to explore the SDK and share your feedback, suggestions, or issues via our GitHub repository.

Anjay Lite is a streamlined version of our robust Anjay LwM2M Client SDK, purpose-built for the most resource-constrained and battery-powered IoT devices. Designed with ultra-efficiency in mind, Anjay Lite eliminates many abstractions and embraces a minimalistic architecture that significantly reduces memory and code footprint. It is purpose-built for highly resource-constrained environments, including bare-metal devices that operate without an operating system or dynamic memory allocation.
By offering developers direct, fine-grained control over resource usage and client behavior, Anjay Lite empowers precision tailoring of LwM2M functionality to the specific constraints and requirements of embedded applications — ideal for sectors such as smart water metering, asset tracking, and environmental monitoring.
While Anjay remains the go-to solution for feature-rich, scalable LwM2M implementations — supporting a broad range of use cases and advanced capabilities, Anjay Lite addresses a complementary need: delivering lightweight LwM2M connectivity without compromise on reliability or standards compliance.
The project has been created and is actively maintained by AVSystem.
For more information and a list of supported features, see the Anjay Lite Introduction.
OMA LwM2M is a remote device management and telemetry protocol designed to conserve network resources. It is especially suitable for constrained wireless devices, where network communication is a major factor affecting battery life. LwM2M features secure (DTLS-encrypted) methods of remote bootstrapping, configuration and notifications over UDP or SMS.

To build the Anjay Lite project, run:
mkdir build
cd build
cmake ..
make -jThis will compile all the examples that use Anjay Lite, along with the test suite in the build directory.
To build and run a specific Anjay Lite example (e.g., from the examples/tutorial/BC-MandatoryObjects directory), you can follow these steps:
cd examples/tutorial/BC-MandatoryObjects
mkdir build
cd build
cmake ..
make -j
./anjay_lite_bc_mandatory_objects <endpoint_name>Replace <endpoint_name> with your desired endpoint name.
To get started with Anjay Lite, refer to our documentation:
This project is available under a dual-licensing model:
- A free license for non-commercial use, including evaluation, academic research, and hobbyist projects,
- A commercial license for use in proprietary products and commercial deployments.
See LICENSE for terms and conditions.
Anjay Lite LwM2M Client SDK comes with the option of full commercial support, provided by AVSystem.
If you're interested in LwM2M Server, be sure to check out the Coiote IoT Device Management platform by AVSystem. It also includes the interoperability test module that you can use to test your LwM2M client implementation. Our automated tests and testing scenarios enable you to quickly check how interoperable your device is with LwM2M.
