An Open Source Graph Database & Document Store

TerminusDB is an in-memory, distributed and open-source graph database and document store. At its heart is a collaboration model providing Git-for-data features such as branch, merge, workflows, and revision control.

CI/CD for your Database

TerminusDB is a powerful open-source graph database. It is immutable and can query any past or present commit. Versions of everything are stored in an extremely compact delta format providing fast query access. This enables highly performant CI/CD data management for stable development environments, frequent iterations, and predictable deployments.

A document-oriented graph database with version control & collaboration model

TerminusDB is designed to make knowledge graph management easier. It combines JSON’s ease of use with the power of graph query. The collaboration model lets many data curators (human and machine) work concurrently with safety and review.

Store Small, Scale Big

TerminusDB has the lowest memory overhead around. Succinct data structures and delta encoding keep things small, just 13.57 bytes per triple. Scale to any size your memory availability allows.

Schema First

The flexible and extendable type-checked schema based on a JSON syntax acts as a blueprint to model data and develop scalable applications. 

Auto UI Generation

Document frames for creating, editing and viewing data are automatically generated from your schema. UI SDK tools make building front ends quick and easy.

Git for Data

A versioning first database, fork, clone, branch, and merge, just like Git, to collaborate with colleagues, time travel, and develop with the safety of undo.

Document Oriented

Work with JSON documents and build relationships between documents in a powerful knowledge graph.

Complex Data Management

From GeoJSON to Markdown, TerminusDB is capable of handling diverse datasets and creating a queryable graph database to power applications, machine learning and AI.

Take a Technical Deep Dive

TerminusDB CTO and Co-Founder, Gavin Mendel-Gleason, has written a three-part blog explaining the technical internals of the open-source graph database and document store, TerminusDB. If you want a technical overview without marketing talk, this series is ideal for you.
