All you need
is models.
Grid is a declarative computational language with a programmable spatial workbook. Define values, relationships, queries, and reactions. Grid keeps the model current.

Start with a result you can verify.
Runnable source, visible checkpoints, and a clear next move—before you need the full reference.
Build your first reactive model
A complete profitability model with an override, status, semantic signal, and readable summary.
Start buildingDeveloper quickstart: model to dashboard
Load a portable revenue model, follow its named outputs into a Layout surface, and prove the UI stays synchronized after one source change.
Follow the build →From arrays to data pipelines
Turn paired series into cumulative and scenario analytics, then choose native collections when the job needs keyed, unique, or queued state.
Follow the build →Debug and harden a model
Separate failed business checks from error values and compiler diagnostics, then add explicit recovery and guarded write contracts.
Follow the build →Choose a path
Start with the thing you want to build.
Canonical reference when you need precision; short paths when you want momentum.
Build your first model
Go from typed inputs to a reactive, inspectable model in fifteen minutes.
Follow the guided build →02Learn the language
Cells, semantic names, queries, predicates, rules, and typed values—one model.
Explore the language →03Study canonical models
Read exact source for analytics, live data, optimization, simulation, and more.
Browse examples →04Build an app
Turn model inputs and outputs into a routed, interactive App without moving state out of Grid.
Build your first Grid app →One model, many surfaces
Spreadsheet formulas. Semantic names. Relational queries. Rules.Simulation. Optimization. Graphs. Geo.
From docs to distribution
Take what you build into the commons.
