The talk is not about pdf viewers but about framework/APIs that developers can use to build all those 'others' solutions. pdfjs.express makes this a piece of cake, you get the source, and companies can outdo competition will less developer $$$ sunk into reinventing the wheel

No, Express will be available under dual AGPL/commercial license.

Actually express is already open sources ( see other messages ) and will be licensed under dual commercial/AGPL terms ... like iText ( bit.ly/2JD0Yj0 ), another popular PDF OSS

See other messages. The code is available and will be licensed under dual commercial/AGPL terms (similar to bit.ly/2JD0Yj0)

We are in the process of updating the site. The product will be licensed under dual GPL/commercial terms (re: what it means see bit.ly/2JD0Yj0)

It's https://opensource.org/licenses/AGPL-3.0 Or summary of what it means bit.ly/2JD0Yj0

If you are talking about info on the site & git, we are working on it. There will be many changes over next few weeks. Stay tuned :)

It is available under dual AGPL/commercial license so indeed it's open source by any definition. We'll clarify this on the site. Thanks for feedback

I am not "him" :) though I work at PDFTron

As Nick says the project is open source (https://github.com/PDFTron/webviewer-ui).

Express is available under under dual AGPL/commercial license ( similar to iText and lot's of other popular OSS )

I don't think this solution is doing what you are looking for. To detect tables reliably in PDF you need some heavy-duty AI like https://www.pdftron.com/pdf-tools/pdf-table-extraction/

Or Linux Red Hat, iText Lib ( open sourced but under AGPL) etc. There is tons of open-source out there under commercial terms.

This is a commercially supported solution so the price is actually not bad ( given alternatives )

It's open source.

It's an extension of pdf.js, not a fork.

No doubt, WebAssembly has lot's of going for it. I think the purpose of the article was to bring awareness around current performance and memory limitations so that WebAssembly can live to its full promise. Not so much an argument to keep PNaCl around.

mpweiher, you are correct! PSPDF is a pdfium lipstick. You can find its license in binary sdk-s or simply ask them. Included or derived work must be disclosed!

Also using the pdfium via Enscripten is not news (https://github.com/coolwanglu/PDFium.js is 3 years old).

On commercial, battle tested side PDFTron offers PDFNetJS & WebViewer for years https://blog.pdftron.com/2015/11/10/pdfnetjs-html5-pdf-viewe... (http://xodo.com/app is the demo referenced in the presentation).
