Better tools for Business Central developers.

Open source, built by people who use them every day.

Business Central development deserves better tooling than it has. Fast tests. Real language analysis. Editors that understand AL. Profilers that point at the actual problem.

Some of that means building things that did not exist yet. Some of it means finding out that a limit everyone works around was only ever an assumption.

These are the tools that came out of that.
