TerminusDB Server

Build Status

TerminusDB is an open source, model driven, revision controlled RDF graph database for distributed collaboration designed for the web-age.

TerminusDB allows you to push, pull, time-travel and merge graphs, much in the way that is possible in git.

TerminusDB Server provides TerminusDB with a RESTful API for interacting with knowledge graphs via the JSON-LD exchange format. This means you can easily compose applications within your own toolchain which utilise the powerful features of graph search and graph storage.

We use an advanced git-like model, storing append only changes to graphs represented in succinct datastructures using terminusdb-store. You can read a description of the architecture in our Succinct Data Structures and Delta Encoding for Modern Databases whitepaper.

TerminusDB's delta-encoding approach makes possible branch, merge, push, pull, clone, time-travel and other git-like operations on a fully featured graph database.

Latest Version


Getting Started

For Windows and Linux, Desktop versions of TerminusDB can be found in our Download Center

For development and testing, as well as Mac users, we recommend our TerminusDB Bootstrap installer, which uses the Docker image

Building from source

In order to build from source, follow the build from source directions.

Open Console

Once you have installed terminusdb-server either from the docker image or built from source you can go simply enter the server location into your browser to view your database from the console "http://SERVER:PORT/". (the default is: http://localhost:6363/).


TerminusDB will:

  • Give you collaboration features currently available in git, but designed to work well with large datasets
  • Make complex data models easy, maintainable and enforced.
  • Overcome the Object Impedance mismatch without turning your Database into an incomprehensible soup.
  • Allow you to search for repeating patterns using recursion.
  • Enable the sharing of data using linked open data formats RDF and JSON-LD making scientific or organisational information sharing easy.
  • Branch, clone, merge, time-travel, push and pull all facilitated by our delta-encoding approach
  • Help you automate the production of UI and data-entry by knowing what data means.


In order to begin manipulating and querying your database you can simply point your browser to "http://SERVER:PORT/" which should allow you to manage and query your database.

You can also perform all configuration, querying and management functions via the RESTful API. We have a number of client libraries to help you get started:

The JavaScript client libraries give you assistance with programatic access.

The JavaScript dashboard is an example application allowing manipulation of the database using the javascript client fluent syntax.

The Python client libraries allow you to use a pythonic syntax to query the database.


In order to use your TerminusDB through the console rather than directly through clients you should look at the documentation on our TerminusDB documentation website.
