Best Industrial Data Platforms in Spain (2026)

This comparison covers the main industrial data platforms available in Spain in 2026: N3uron, Savvy Data Systems, Nexus Integra, Ignition (Inductive Automation), atvise, Rapid SCADA and Captia (Captia Connect and Captia.ai). There is no best platform in the abstract: there are different profiles for different use cases. That is why the table uses only criteria that can be verified on each vendor's public website, declares anything non-public as not published, and closes with a verdict by use case, including the cases where Captia is not the best option.

How we put this comparison together

We are an interested party: Captia appears in the table. To keep the comparison useful despite that, we apply three rules. First: every claim about a competitor comes from its public website, checked in August 2026, with no third-party interpretation. Second: when a vendor does not publish something (pricing, for instance), the cell says it is not published, in our column too. Third: the verdict is given by use case, not by ranking, because an Austrian web SCADA, an edge platform from Madrid and an open source project do not compete in the same league or for the same buyer.

The criteria are five: deployment type, licensing model (where public), whether it includes a web SCADA or web visualisation, origin and support, and main focus. What an industrial data platform actually is, layer by layer, is covered in our guide to the industrial data platform and on our industrial data platform page with Captia Connect and Captia.ai.

Profile of each platform

N3uron

A Spanish edge and industrial DataOps platform, built to capture, normalise and distribute plant data with a per-module licence that does not limit tags or clients. It publishes its pricing, which is unusual in this sector, and runs on anything from a Raspberry Pi to a cloud server. It is the natural choice for technical teams who want to build and operate their own connectivity layer.

Savvy Data Systems

A company from San Sebastián focused on bringing analytics and AI close to the machine, with a consolidated presence in sectors such as machine tools and advanced manufacturing. Its proposition puts the weight on analytical exploitation of the data rather than on SCADA-style supervision.

Nexus Integra

A Valencian industrial operations platform built on big data, aimed at organisations with several assets or sites that want a single corporate layer: Smart SCADA, alarms, reports and advanced analytics within the same product.

Ignition (Inductive Automation)

The international heavyweight of the list. Its per-server licence with unlimited tags and clients changed the rules of the SCADA market, and its Perspective module deploys web and mobile clients with no per-seat licences. It demands engineering: it is a platform on which an integrator builds the solution, not a turnkey product.

atvise

A SCADA and HMI built on pure web technology over OPC UA, developed in Austria. Its strength is visualisation: web-native screens with no plugins and no client licences. It covers the supervision layer, not the full data platform layer.

Rapid SCADA

An open source project with a free Community edition and no data point limits. For a team with in-house technical capacity and a minimal budget it is an honest starting point; the real cost shifts to engineering hours and self-managed maintenance.

Captia (Captia Connect + Captia.ai)

Our proposition separates two layers. Captia Connect is the data layer: multi-protocol acquisition (OPC UA, MQTT, Modbus TCP and RTU, IEC 870-5-102, REST, among others), normalisation, local buffering with persistence during outages, and local, hybrid or cloud deployment. Captia.ai is the intelligence layer: web SCADA, dashboards per asset or plant, rules, alerts, workflows, reporting, APIs and AI modules such as anomaly detection, forecasting and energy optimisation. Implementation is done by the same team that builds the product.

Verdict: which one to choose for your use case

In-house technical team wanting to build its own connectivity layer with pricing in plain sight: N3uron. Its published pricing and per-module model make budgeting easy without talking to sales.
Bespoke corporate SCADA with an integrator behind it: Ignition. Ecosystem, community and an unlimited per-server licence; the engineering project sits with the integrator.
You only need web visualisation on an OPC UA base: atvise. It does one thing and does it web-natively.
Minimal budget and technical hands to self-manage: Rapid SCADA. Free in its Community edition; you pay in your own hours what you do not pay in licences.
Analytics and AI across machine fleets, with a focus on advanced manufacturing: Savvy Data Systems.
A single corporate layer for multi-site operations: Nexus Integra.
An industrial SME that wants the data captured properly and the intelligence layer on top, with a single team implementing and supporting it: Captia Connect and Captia.ai. If your case is one of the above, the other options on this list will serve you better; if it is this one, let's talk.

Where Captia fits on this map

Captia does not compete with Ignition on ecosystem size or with Rapid SCADA on licence price. It competes in a specific gap: the small and mid-sized manufacturer that does not want to run a platform, but to have its plant data captured once, normalised and turned into decisions. The data layer (Captia Connect) and the intelligence layer (Captia.ai) are implemented in phases and without rip-and-replace, with the architecture we describe on the industrial data platform hub. The usual starting point is a mapping of machines, protocols and value, not a licence.

Frequently asked questions

What is the best industrial data platform in Spain in 2026?

It depends on the use case. To build your own connectivity layer with published pricing, N3uron; for a corporate SCADA with an integrator, Ignition; for pure web visualisation over OPC UA, atvise; for a minimal self-managed budget, Rapid SCADA; for analytics and AI across machine fleets, Savvy Data Systems; for a corporate multi-site layer, Nexus Integra; and for an SME that wants data and intelligence implemented and supported by a single team, Captia Connect and Captia.ai.

Which platforms on this list are Spanish?

Four: N3uron (Madrid), Savvy Data Systems (San Sebastián), Nexus Integra (Valencia) and Captia (Valencian Community). Ignition is American and is implemented in Spain through integrators, atvise is Austrian and Rapid SCADA is an international open source project.

Which platforms publish their pricing?

Of the seven compared, N3uron and Ignition publish pricing on their websites, and Rapid SCADA offers a free Community edition. Savvy Data Systems, Nexus Integra, atvise and Captia do not publish price lists and work through per-project quotes or sales enquiries.

Is an industrial data platform the same as a SCADA?

No. A SCADA supervises and controls the process in real time; a data platform captures, normalises and distributes the data to every application that needs it. Some solutions on this list cover only one layer (atvise is visualisation, Rapid SCADA is a SCADA) and others combine both. We explain the full difference in our guide to the industrial data platform.

If, after comparing, you want to see what this architecture would look like in your plant, our industrial data platform page explains how we build it with Captia Connect and Captia.ai, starting with a mapping of what you already have.
