License Proprietary

Confirms current value; MemGQL Community is distributed as a free binary without an open-source licence, and the Enterprise edition is under Memgraph's own commercial licence, so neither edition carries an OSI/SPDX licence.

Released 2026-03

Confirms current value; the changelog's earliest entry is v0.1.0 on March 29th, 2026. Note the memgraph.com/memgraph-zero landing page separately states 'Launched May 2025', which conflicts with the changelog and could not be reconciled from available sources, so the changelog date is preferred as the more concrete, versioned release record.

Language Rust

No current value was set. The memgraph.com/memgraph-zero page states MemGQL is 'Built in Rust', and its third-party attributions list is entirely Rust crates (antlr4rust, tokio, serde, etc.), including one described explicitly as a Rust parser runtime.
