Comparison · Litmus Edge

The same category, approached from the cloud side.

Litmus Edge is the product most like ours: connectivity, data operations, analytics and applications in one edge-native platform. We take that seriously enough to write this page carefully. The difference is emphasis: Litmus leads with the cloud and AI destination, we lead with what the plant keeps and controls.

What it is
Litmus Edge: Industrial edge data platform, from Litmus
What Proxus is
An industrial data platform: collect, model, govern, store, deliver
Honest summary
The closest direct competitor. Same category, cloud-and-AI-forward, with a published entry price.
Your options
Usually one or the other, not both: keep Litmus Edge or move the job into Proxus. How to evaluate the two side by side is below.

Give them their due

What Litmus Edge is genuinely good at.

A comparison that only lists the other product's weaknesses is a sales sheet, not a decision aid. These are real strengths, and some of them are reasons not to buy Proxus.

  • A complete, well-packaged product family

    Litmus Edge, Edge Manager for fleet management, Unify for the namespace, a data catalogue and an MCP server, as Litmus describes its product family.

  • Strong cloud and AI positioning

    If the programme is driven by a cloud data platform or an enterprise AI initiative, Litmus speaks that language natively and has the reference architectures to match.

  • Published pricing and a free Developer Edition

    A published entry price and a free Developer Edition let an engineer start without a sales call.

  • Market presence and customer proof

    Litmus publishes customer stories. That kind of reference weight is earned over years and we do not claim to match it.

Attribute by attribute

Where the two actually differ.

Both columns are filled in. Where Litmus Edge is ahead, the row says so.

  • Category

    Proxus

    Industrial data platform, positioned as the governed layer between plant equipment and everything else.

    Litmus Edge

    Industrial edge data platform, positioned as the data foundation for industrial AI.

  • Product shape

    Proxus

    One platform. Namespace, historian, dashboards, rules, delivery and AI access are in the same deployment.

    Litmus Edge

    A family: edge platform, central manager, namespace product, data catalogue and MCP server, licensed in tiers.

  • How the runtime is built

    Proxus

    One gateway process at the edge with the drivers, rules, MQTT broker and every outbound client, plus a messaging container next to it that holds the local buffer.

    In the docs: How the runtime is built

    Litmus Edge

    A platform family with containerised applications and marketplace apps running alongside the core.

  • Where the emphasis sits

    Proxus

    Keeping the plant self-sufficient first: model, history and dashboards on a hub you host, with the cloud as one target among many.

    Litmus Edge

    Getting plant data into cloud analytics and AI, repeatably, across many sites.

  • Unified Namespace

    Proxus

    Part of the core platform, not a separate purchase.

    In the docs: Unified Namespace

    Litmus Edge

    A distinct product in the family.

  • Pricing transparency

    Proxus

    Published recommended prices from $5,500 a year, priced only by gateways and data rate; partners quote local terms.

    Pricing: Pricing transparency

    Litmus Edge

    Foundation tier from $1,500 per month as published (checked October 2026); Growth, Scale and the UNS add-on by quote.

  • Air-gapped operation

    Proxus

    Designed to run fully air-gapped, including the hub, with no outbound requirement at all.

    Litmus Edge

    Litmus Edge runs offline; Litmus Edge Manager can be hosted in the cloud or on-premises. Confirm fully air-gapped operation for your topology.

  • Company scale

    Proxus

    A focused engineering company with ISO 27001 and ISO 9001 certified processes; you work directly with the product team.

    Certificates: Company scale

    Litmus Edge

    A larger organisation with a wider partner and analyst footprint.

Proxus figures come from the current build's own driver and target inventory. Litmus Edge figures come from the vendor's published material, linked at the end of this page. Nothing here is measured on a benchmark neither party has agreed to.

Choose Litmus Edge

When we are not the answer.

  • The programme is defined by a cloud data platform or an enterprise AI initiative, and alignment with that ecosystem is the priority.
  • You need a larger vendor with wider partner and analyst coverage to satisfy procurement.
  • You want to install the software on your own hardware today without talking to anyone.
  • Your architecture team has already standardised on their product family.

Choose Proxus

When the shape of the problem fits.

  • The plant must keep working, and keep its data, with no cloud dependency whatsoever, including fully air-gapped sites.
  • You would rather buy one platform than a family of products.
  • You want a price set by two numbers (gateways and data rate), with tags, devices and users never counted.
  • You want direct access to the engineers who build the product.

Not either/or

How they are used together.

  • They are substitutes, not layers

    Unlike the other comparisons on this site, this is a genuine either/or. Running both in the same plant means two namespaces competing to be the model, which helps nobody.

  • Evaluate both against your own line

    Both products demo well. The honest test is a real machine, a real protocol and a real destination system, run for a week, including what happens when the network drops.

  • Ask both the same questions

    What happens with no internet for a month? What is licensed per tag? What is a separate product? Who answers at 02:00? The answers separate the two faster than a feature grid.

Questions

Proxus and Litmus Edge: short answers.

Can Proxus run fully air-gapped?
Yes. Proxus is designed to run fully air-gapped, including the hub, with no outbound requirement at all.
How does pricing compare?
Proxus publishes recommended prices from $5,500 a year, priced only by gateways and data rate. Litmus publishes its Foundation tier from $1,500 per month; Growth, Scale and the UNS add-on are by quote (checked October 2026).
Is the Unified Namespace a separate purchase?
Not in Proxus: it is part of the core platform. In the Litmus family it is a distinct product.
Should Litmus and Proxus run together?
Usually not. They are substitutes, and two namespaces in the same plant compete to be the model. Evaluate both against a real machine, a real protocol and a real destination system instead.

Next step

Run the same test on both products.

Pick one machine, one protocol and one destination system. Set up the Proxus side on your own line with an evaluation key, watch what happens when the network drops, then ask both vendors the same questions.
