Compatibility Matrix
Elide compatibility is tracked in the external
elide-dev/testsuite repository. The
matrix below reflects the latest report checked into these docs from
reports/index.json.
These numbers are measured pass rates for one Elide build and one upstream test revision. They are not a standards certification, and they should be read with the linked testsuite report when you need exact coverage details.
Use this page for directionally comparing Elide's runtime and toolchain behavior with upstream suites such as Test262, CPython core tests, and javac jtreg. For product behavior, prefer the language and API docs; for exact test coverage, inspect the raw testsuite report.

Reproduce The Results
To build and run the compatibility suites yourself, follow the directions in
the elide-dev/testsuite repository.
The checked-in report used by this page is available as raw data:
curl -fsSL https://raw.githubusercontent.com/elide-dev/testsuite/main/reports/index.jsonThe report records the Elide build identifier, upstream suite revision, pass, fail, error, skipped, and regression counts for each suite.
