About LangIndex

LangIndex is an open source, self-hosted reference for programming languages. Its goal is to help developers compare languages by practical fit, constraints, tooling, governance, and tradeoffs.

The repository is the source of truth. Content changes arrive through normal pull requests, with factual claims backed by official sources whenever possible.

Editorial standard

• Prefer official sources: specs, docs, release notes, governance pages.
• Cite claims that are not obvious from the linked official resource.
• Separate facts from judgment. Mark unknowns directly.
• Use neutral, practical language. No advocacy.
• Every substantial page includes a lastVerified date.
