Your infrastructure, not ours
No hosted service in the middle, no per-document metering, no outage of ours that becomes an outage of yours. You deploy it and you own the uptime.
PorticoSoft · developer tools for .NET
Software that runs where you put it.
We build for .NET teams who would rather own the thing than rent it. What we ship installs into your application, runs on your infrastructure, and does not call home while it works.
Everything on the right is a real file, generated by Paragon from an HTML template and a JSON payload. No Office on the server, no network call while it renders.

- DOCX letter
- PPTX deck

How we build
Three commitments that shape what we ship, not a page of values.
Nothing leaves the machine
Our products handle the documents a business would least like to see leave its network. So they are built not to send them anywhere — enforced in code, not promised in a policy.
Written for developers
Plain formats, small surfaces, and no proprietary designer file you cannot read. If a thing can be a folder of HTML instead of a binary, it is one.
What we make
Paragon
AvailableA reporting engine for .NET. Templates are ordinary HTML pages — your CSS, your charting library, your fonts — or a real Word or PowerPoint file with the same bindings typed into it. The engine binds JSON into one and returns the file that report was designed to produce, at exact fidelity. Right-to-left handled properly.
