API Self-hosted option

Self-hosted Options

Draftable API Self-hosted is built for on-premise deployments. It is supplied as a virtual appliance and comparisons run entirely in that appliance. That means the confidentiality and privacy of your data is guaranteed.

If you aren't sure you need an on-premise solution, we recommend starting with our Draftable-hosted option. Both options provide the same API, so it's easy to switch to Draftable API Self-hosted at a later date.

At this stage, only PDF comparisons are supported, but a number of options are available to support other file types.

Interested in Draftable API Self-hosted? Great!

Easy integration

If you are working in C#/.NET, Java, Python, or Node.js, our client libraries make integration easy.

From other languages, you can still use our simple REST API.
