How platforms were chosen, what was compared, and what this site does not claim to know.
Ten, picked to span the real spread of the problem rather than to be exhaustive: embedded Linux and microcontrollers, hosted and self-hosted, commercial and open source, and both the general-purpose tools and the two silicon-vendor platforms that a lot of products quietly end up using. Anything that only manages configuration, or only ships apps to phones, is out of scope.
Target hardware, deployment model, rollback mechanism, published pricing, free tier and open-source status — taken from vendor pricing and documentation pages in August 2026. Every price on this site was read off the vendor’s own page, not estimated.
No devices were flashed for this comparison. There are no benchmarks, no update-time measurements and no reliability testing here, and pretending otherwise would be worse than useless in a field where the failure mode is a dead product. Enterprise pricing is negotiated; the published figures are list prices and a starting point for your own quote.
Links to sibling sites appear only where the subject genuinely continues — update signing leads to certificates and key management, for instance. There is no reciprocal footer block on every page, because a ring of new domains linking to each other with identical anchor text is a pattern, not a service to the reader.
Every page shows the date it was fact-checked. Pricing in this category moves — Golioth restructured theirs in 2026 — so treat figures as a snapshot. If something here has gone stale, say so and it will be corrected.
No platform pays for inclusion, position or wording. Table order is editorial. Any commercial relationship would be stated on the disclosure page and marked on the link itself.
