Replaces

It replaces a lot.

The interface is a spreadsheet. The engine underneath does the work of the most expensive line items on your software invoice — in the same cells, on the same dependency graph, with the same undo.

Instead of
Excel · Google Sheets

The spreadsheet, obviously.

=SUM(D2:D4)

2,903 built-ins with Excel-compatible names, spilling arrays, live collaboration — plus a type system and a dependency graph the originals never had.

the interface stays

Instead of
Tableau · Power BI · Looker

BI without the export.

SELECT … GROUP BY region

Joins, CTEs, and window functions pushed down to BigQuery, Snowflake, Redshift, or Databricks. Grouped KPIs stay maintained incrementally as rows change.

no per-viewer seats

Instead of
Mathematica · Maple

Exact algebra.

SYMBOLIC.SOLVE(p, x)

Simplify, factor, differentiate, solve exactly — and every transformation carries a replayable certificate.

was: a five-figure license

Instead of
MATLAB · SciPy

Scientific computing.

ODE_SOLVE(f, y0, tspan)

ODEs and PDEs, eigendecompositions, FFTs, curve fitting, splines — reactive, in cells, no toolboxes.

no toolbox pricing

Instead of
Gurobi · CPLEX

Solvers as syntax.

SOLVE … MINIMIZE cost

Goal seeking, linear and mixed-integer programs, shadow prices, and infeasibility diagnostics — as first-class statements.

was: call for pricing

Instead of
@RISK · Crystal Ball

Uncertainty, built in.

VAR_MONTE_CARLO(r, 0.95)

This function uses deterministic normal-quantile scenarios to estimate risk. For a seeded path estimator with a sample standard error, use the finance research simulation starter in a matching Grid version.

explicit method assumptions

Instead of
MS Project · Primavera

Real scheduling.

PlanHandle · optimal

Precedence, resource limits, calendars, changeovers, weighted tardiness — behind a Gantt surface with honest solve statuses.

solver-grade, not bars on a timeline

Instead of
OR-Tools · APS modules

Routing & MRP.

RoutePlanHandle

Multi-depot vehicle routing with time windows; multi-level MRP / ATP that recomputes only what a supply change can actually affect.

was: an enterprise module

Instead of
Postman · SDK glue

APIs become functions.

catalog.listItems(…)

Import OpenAPI, GraphQL, AsyncAPI, WSDL, or gRPC as a versioned package; call typed operations straight from formulas.

schema-checked at import

Instead of
Drools · Prolog

Logic with receipts.

WHY(cell)

Derived predicates over the model graph, modal MUST / MAY / CANNOT — and every inference explains itself.

every answer shows its evidence

Instead of
ANTLR · lex/yacc

Grammars, first-class.

PARSE(text, parser)

CFG, PEG, and regular grammars in source; generated LALR / Earley / packrat parsers; trees you can query like any value.

parse trees are values

Instead of
Gambit · consultants

Certified equilibria.

GAME.ANALYZE(g)

Nash equilibria with checkable certificates, dominance and welfare analysis, mechanism checks with concrete counterexamples.

proofs, not vibes

Instead of
Biopython · RDKit

Lab-grade functions.

BIO_ALIGN(a, b)

Sequence alignment, variant summaries, molecular fingerprints, docking — beside hundreds of physics and chemistry functions.

one namespace away

Instead of
ArcGIS · PostGIS glue

Geometry that computes.

parcel inside district

Spatial predicates, H3 aggregation, projections, great-circle math — and a map surface bound to cells.

maps are a surface, not an app

Instead of
Zapier · cron jobs

Automation that lives with the data.

EVERY cron"0 * * * *"

WHEN rules with debounce, throttle, and durable queues; schedules with SKIP MISSED or BACKFILL; provider-compatible webhook signatures for GitHub, Stripe, and Slack.

no per-zap pricing

Instead of
Airtable · Retool · Jupyter

Many views, one model.

/embed/<token>

Tables, maps, charts, documents, notebooks, and the App builder present the same model. In Grid 0.66.8, Code, Data, App, and Chat organize how you work with those views: author source, inspect values, use an app, or discuss a model. Documents and notebooks keep their own editors; changing layers does not create another copy of the calculations.

one model under all of it

Fewer tabs. Fewer licenses. One dependency graph.

Not every feature of every product — the core work most teams buy them for: modeled, computed, versioned, and explained in one place, by one engine.

Everything on this page ships today and is specified in the language docs — no roadmap items, no asterisks.
