Show HN: OM Core – multidimensional models without spreadsheet cell formulas

A bold bid to kill spreadsheet chaos has commenters asking: is this the future or just more work

TLDR: OM Core is a new open-source tool trying to replace messy spreadsheet formulas with a cleaner system for business models. The early community reaction instantly turned into a bigger fight over whether spreadsheets need saving at all — or whether AI and code will wipe them out anyway.

A new open-source project called OM Core just strutted onto Show HN with a big promise: stop building important business models around fragile little spreadsheet boxes. Its creator says the idea is simple in theory but spicy in practice — instead of tying everything to cell locations, you describe the business logic in a cleaner, more structured way, then let the grid be just a view. In plain English: the spreadsheet is no longer the boss.

And the tiny but telling comment thread instantly went into "spreadsheet end times" mode. The creator, cloudcell, came in with a calm, almost vulnerable pitch, saying it’s early alpha software and asking spreadsheet survivors whether the idea even makes sense. That alone gave the launch a bit of underdog energy: not “we solved finance forever,” but “please tell me if this is understandable before I embarrass myself.”

Then came the classic internet escalation. One commenter dropped a link to a post predicting that AI-generated code will replace spreadsheets entirely, basically tossing a grenade into the room: why build a better spreadsheet model at all if code is about to eat the whole category? That’s the real drama here. Is OM Core a rescue mission for spreadsheet-weary workers, or a bridge technology before everything becomes code and prompts? Even with only a couple comments, the mood is deliciously tense: one side wants salvation from formula hell, the other is already planning the spreadsheet funeral.

Key Points

  • OM Core is an open-source alpha multidimensional modeling engine for structured financial, operational, and analytical models.
  • The system models data and logic with dimensions, cubes, groups, hierarchies, rules, and views instead of spreadsheet cell formulas.
  • The article says OM Core separates model structure, business logic, layout, presentation, calculation flow, and user interaction.
  • The current repository contains the full alpha application stack, including engine, command tools, REPL, GUI/TUI, runtime, scripting, plugins, storage-adapter, examples, and tests.
  • OM Core currently runs from source on Linux, macOS, and Windows, using uv to manage its Python environment and start scripts for different runtime modes.

Hottest takes

"separate the model from the grid" — cloudcell
"prediction re the end of spreadsheets" — densekernel
"anything that is currently modeled as a spreadsheet is better modeled in code" — densekernel
