KoliLang

A SAS engine that runs in the browser. WebAssembly under the hood, DuckDB for the heavy lifting, byte-parity with SAS for the procs we cover.

Open the editor

Live now. The browser editor runs at editor.kolistat.com — no install, free to use. Premium procs are landing one at a time; get in touch for early access.

What it does

Reads, understands, and runs your SAS programs. — macros, formats, data steps, the works.
Runs in the browser, no install. WASM + DuckDB-wasm means the entire editor and runtime fits in a tab.
Byte-parity where it counts. When the spec says the number should match SAS, the number matches SAS.

Procedure tiers

KoliLang ships with a deliberately generous free tier — the procs most teams use every day — and a paid tier for the procedures that drive most of the real revenue work.

Tier	What you get	Procs
Free	Workhorse procedures for data prep, descriptives, and routine reporting. No account required.	SQL · PRINT · SORT · MEANS · FREQ · TRANSPOSE · CONTENTS · FORMAT · IMPORT · EXPORT · UNIVARIATE
Paid	Premium reporting and the modelling procedures. Per-seat license; 30-day offline trial.	REPORT · TABULATE · COMPARE · LOGISTIC · GLM · MIXED · GENMOD · LIFETEST · PHREG · REG · ANOVA · NPAR1WAY

30-day offline trial. The paid tier unlocks for 30 days the first time you open the editor, no card required. After that, a license key keeps it active.

Where it stands

The engine parses the production-grade SAS corpus we test against without diagnostic noise, and the curated set of tables and listings produces byte-parity output against SAS. Paid procs are landing one at a time, with the same parity bar.
