ImBrain™
An Open-Architecture Industrial Historian for the Modern Plant
0.1 — Draft · March 2026
Author: Branimir Georgiev, Imbra
Industrial historians fall into two categories: enterprise platforms priced at six figures with multi-year implementation projects, and siloed SCADA databases that cannot be queried, aggregated, or reasoned over. Small and medium plants are left with spreadsheets, manual shift reports, and no cross-site visibility. Enterprise plants pay for capabilities they use at ten percent capacity, locked into vendor ecosystems with no migration path.
ImBrain is an open-architecture industrial historian that stores time-series data, alarm events, lab results, and virtual tags — connects plants in a mesh — and lets operators query everything in plain language. The core and agents are open source under AGPL. Analytics plugins are commercial. It runs air-gapped on a $500 industrial mini PC and scales without architectural changes to enterprise mesh deployments spanning hundreds of sites.
