SkySpark vs Clockworks Analytics
Both of these are fault detection and diagnostics products, so this is a genuine like for like comparison. They answer the same question, which is why a building is behaving badly, and they answer it in opposite ways. SkySpark is a toolkit. Clockworks is an application. That single distinction drives almost every other difference, including the commercial one.
SkySpark is the deepest analytics toolkit in this category. SkyFoundry documents more than 500 built in analytic functions plus a Rule App for writing your own, open published APIs and a native Project Haystack REST API supporting a consistent semantic data model across mixed vendor equipment. It runs on premises, in the cloud, at the edge or on the desktop, a deployment range nothing else here matches and often the deciding factor for data residency or air gapped sites. Verified capability spans fault detection, anomaly detection, energy metering, water and gas, documented API, dashboards, building system integration, reporting and tariff analysis. That is the widest verified feature set of any fault detection product reviewed.
Clockworks is the more finished product. Its differentiator is not the number of rules but what it does with the output: diagnostics are ranked by avoidable cost, which turns a fault list into a prioritised work queue. That directly addresses the usual failure mode of building analytics deployments, which is not that the software fails to find faults but that nobody acts on the thousands it finds. Expert system diagnostics plus an information model and condition based maintenance mean it names likely causes rather than only flagging that something looks unusual. It also publishes a CMMS Integration Developer Guide documenting a REST API with core-base and workorders containers, named POST and PATCH endpoints, task status values, equipment identifier mapping and subscription key authentication. The CMMS pulls tasks flagged for work order generation, writes the work order identifier back, and keeps status in step until the work order completes. That is a properly specified two way integration.

Clockworks Analytics
Fault detection and diagnostics platform for building systems that plugs into existing building systems and ranks diagnostics by avoidable cost. Includes an information model, expert system diagnostics, condition based maintenance and an AI assistant.
Full profileThe main differences
The commercial difference is the real decision
SkySpark is sold almost entirely through value added resellers, distributors and OEMs, not direct. SkyFoundry cites more than 140 partners worldwide. Resellers bundle the software with implementation services, training and support, so the total cost of a deployment is set by the partner, and on smaller projects professional services can exceed the licence. No prices and no licence terms are published anywhere, so the model, the renewal basis and any point or data volume limits must be obtained in writing from the partner. The consequence buyers underestimate: two SkySpark deployments can differ enormously, and the deployment quality is the partner quality. Reference checks should therefore be checks on the integrator, not on SkyFoundry.
Clockworks publishes no pricing either, and does not state the pricing basis. Whether it is per building, per point or per square foot determines how cost scales across a portfolio, so establish it in the first call.
Where each is thinner
- Clockworks is the thinner record. The marketing home page is most of what is readable, and attempts at its integrations and platform pages both returned HTTP 404. Energy metering, anomaly detection, dashboards, mobile access, benchmarking, water and gas, tariff analysis and demand management could not be verified from published sources. Its API and CMMS position, by contrast, is now well documented via its own developer guide.
- Neither publishes a protocol list. For products whose entire function depends on reading building automation data, no BACnet, Modbus, MQTT or OPC support is named by either vendor. SkySpark material mentions live links to automation systems and smart meters, SQL databases, Excel and utility web service feeds. Clockworks says it plugs into existing building systems. Both are generic statements, and both leave you to close the gap yourself.
- Clockworks CMMS integration names no specific CMMS products, so it is built against the API rather than supplied as a prebuilt connector, and no single sign on is documented.
- SkySpark is a platform, not a finished application. Buyers expecting to subscribe and log in to a complete product have misunderstood what they are buying.
Neither one covers the money
Both are pure diagnostics. Utility bill management and carbon reporting could not be verified for either, and benchmarking is unverified for both. Each must be paired with an energy or ESG platform to cover financial and disclosure requirements.

Read the full assessmentWhich to choose
Choose SkySpark if you have, or can buy, real engineering capability and a strong integrator, and if deployment flexibility matters. On premises or edge deployment for a secure or air gapped site, a Haystack semantic model across mixed vendor plant, and custom rules for unusual equipment are things only SkySpark does here. It also targets small, medium and enterprise buyers, which the others in this class do not.
Choose Clockworks if you want faults arriving as a ranked, costed work queue that flows into your maintenance system without you building the pipeline. For an estate with a functioning maintenance team and no appetite for a rules engineering project, that is the more likely route to actual savings, because the bottleneck in FDD is almost never detection.
Two things to settle before signing either. First, protocol compatibility against your actual building systems, in writing, since neither vendor publishes it. Second, for SkySpark, the partner: ask who configures the rules, who owns them afterwards, and what happens if you change integrator. Relevant background: BMS energy optimization, FDD and analytics and threshold vs statistical anomaly detection.
Frequently asked questions
Effectively no. SkyFoundry sells through value added resellers, distributors and OEMs, citing more than 140 partners worldwide, and publishes no prices or licence terms. Your contract, implementation and support all come through a partner, which is why two deployments can look nothing alike.
Clockworks publishes a CMMS Integration Developer Guide with a documented REST API, named endpoints and two way work order status synchronisation, but it names no specific CMMS products, so you build against the API. For SkySpark, CMMS integration could not be verified from published sources.
SkySpark. It is documented to run on premises, in the cloud, at the edge or on the desktop. Clockworks describes itself in its own documentation as a cloud based fault detection and diagnostics platform, and no on premises option could be verified.
No. Both are diagnostics products. Utility bill management, carbon reporting and benchmarking could not be verified for either, so pair whichever you choose with a platform that handles invoices and disclosure.

Disclosure
Alongside advisory work I also build a CMMS and CAFM platform, so I have a commercial interest in enterprise software generally. No vendor here has paid for inclusion, placement or wording, and there are no reseller or affiliate arrangements.
