TuringDB

Protocols HTTP/REST, Native binary

The server speaks JSON over HTTP by default. Started with USE_TURING_PROTO=1 it speaks TuringDB's own binary protocol on that port instead, used by the Python SDK's native backend. Corrects the August 2026 reading, which took the binary backend to be a payload encoding over HTTP; the docs have since been rewritten. Embedded mode is in-process and carries no protocol tag.

• JSON over HTTP against a running server

• The binary protocol is a server-side mode, selected once when the server starts with the environment variable USE_TURING_PROTO=1

Released 2025

No tagged GitHub releases predate v1.20 (Feb 2026), and the GitHub repo itself was only made public 2025-08-01, so there is no formal 'first release' artifact. The earliest Internet Archive snapshot with fully rendered marketing content (the site is a client-rendered SPA; earlier 2025 snapshots only captured the page shell) is from 2025-11-09 and already describes TuringDB as a working graph database engine, supporting 2025 as the year it went public.

• Get answers in milliseconds from the fastest columnar in-memory graph database engine, featuring git-like versioning.
