Introduction - HTTP API · reviewed 2026-08-02
Released 2007
Matches current value. Neo4j's own history page dates the open-source 1.0 release to 2007, after seven years of internal development starting in 2000.
Language Java
Matches current value. Neo4j's own docs name Java as the primary implementation language; Scala is also used within the codebase but Java is the language the project leads with.
