Mandelbit helps companies design, debug, and maintain networking products built on Linux and open-source technologies.
From kernel-level development to production-ready systems,
we work across the full networking stack.
Mandelbit is a technical consultancy focused on solving complex networking problems.
We work with companies building and maintaining products based on Linux and open-source technologies, helping them design robust systems, debug hard-to-trace issues, and keep their codebases aligned with upstream projects over time.
Our work spans the full networking stack, from low-level kernel components and wireless drivers to user-space applications and cloud-managed systems.
We design, extend, and customize Linux-based networking software, working across the full networking stack.
Our work includes kernel-level development, wireless subsystem customization, routing, tunneling, packet processing, and custom protocol design.
We provide deep technical expertise in wireless and mesh networking systems, with a strong background in Wi‑Fi driver development and mesh routing protocols.
We support customers in debugging unstable networks, improving performance, validating complex topologies, and addressing protocol-level issues in production environments.
Many companies rely on open source but struggle to maintain internal changes or keep pace with upstream evolution.
We help teams reduce divergence, upstream features and fixes, and ensure that their products remain secure, maintainable, and aligned with the broader open-source ecosystem.
We typically work as a technical partner, integrating closely with existing engineering teams.
Our customers value direct access to deep technical expertise, responsiveness, and the ability to involve us when specific, complex needs arise.
Most collaborations evolve into long-term partnerships built on trust, reliability, and continuity.
Open source is not just a dependency in our work… it is part of how we operate.
Mandelbit actively contributes to major open-source projects in the networking ecosystem, including the Linux kernel, OpenVPN, OpenWrt, and the wireless subsystem.
This involvement gives us direct insight into how these projects evolve and allows us to build solutions that remain maintainable and production-ready over the long term.
Over the years, Mandelbit has helped companies:
complex networking issues at driver and kernel level
new Linux kernel modules
custom routing protocols for constrained environments
firmware pipelines and reduce long-term maintenance costs
production-ready networking software for embedded and cloud-managed devices
Mandelbit was founded as a technical consultancy focused on networking systems built on Linux and open-source technologies.
Born from years of hands-on engineering experience, the company grew from an independent consulting activity into a structured team working with technology providers, manufacturers, and startups across different markets.
Open source has always been part of this path: not as an ideology, but as a practical foundation for building maintainable, production-ready systems.
