Compare · Papermark
The Papermark alternative for HTML decks.
Papermark is built for PDFs and office files, has a data room, and gives 50 free links where HTMLRadar gives 2. Papermark’s supported-file guide, checked on 19 October 2026, lists HTML files on Business and above. Its public HTML viewer code, read on 14 October 2026, records the whole file as one page; HTMLRadar keeps an HTML deck, brief or proposal as a page and reports which sections each recipient read.

Papermark is a real open-source project with a real team behind it, offering document sharing, data rooms, page-by-page analytics on office files and a free plan of 50 links. The difference that matters is narrow and specific: what the two of us do with a web page.
Where HTMLRadar fits
You already send HTML. You want to keep it as HTML, create per-recipient links, and see which headings or slides held attention.
Related: HTMLRadar vs DocSend, DocSend vs Papermark compared, the free PDF-to-HTML converter, free tools for turning HTML into a link, HTMLRadar pricing, tracked links on your own domain, security and data handling, HTMLRadar vs LiveSend, and track an HTML deck.
- The document is an HTML file.
- You drop the .html file in, or paste a URL you already host. Fonts, layout, links and interactions all still work for the recipient.
- You want to know which section they read.
- Each recipient gets their own link, and the report tells you which headings or slides they read and for how long.
- You hold a PDF today.
- Convert a PDF deck into a single HTML page for free in your browser, with no account needed to convert and download, and see whether the HTML version is the one you would rather send.
- You want one flat price.
- HTMLRadar Pro is $19 a month or $190 a year for one person with unlimited tracked links, and a custom domain is included in Pro, with one CNAME record.
What HTMLRadar does not do
HTMLRadar has no data room, granular per-file permissions, NDA agreements, dynamic watermarking or screenshot protection. Its section-level reading data is for web pages: a PDF or office file rides along as an attachment under a tracked link, and the converter turns a PDF deck into a web page when you want the reading data. Papermark covers documents that are PDFs or office files, a data room with granular file permissions and NDA agreements, and the largest free plan of the two. On Team and Enterprise, readers can sign in with a Microsoft work account instead of an e-mail code, on htmlradar.page links that confirm the reader's e-mail. See HTMLRadar pricing (checked on 19 October 2026).
Can you upload an HTML file to Papermark?
Papermark’s supported-file guide, checked on 19 October 2026, lists HTML files on Business and above. If HTML is not enabled in your account, it says to contact support. In Papermark’s public code, read on 14 October 2026, the HTML viewer records the whole file as one page, so reading time is for the file as a whole, and an HTML file is limited to 3 MB. HTMLRadar takes the .html file directly, or a URL you already host, keeps it as a page and reports which sections each recipient read.
Is Papermark or HTMLRadar the better DocSend alternative?
They answer different questions. Papermark offers document sharing, data rooms, page-by-page analytics on office files, and a much larger free plan at 50 links. HTMLRadar is narrow: it tracks HTML pages section by section. Papermark is built for PDFs and data rooms. Papermark’s supported-file guide, checked on 19 October 2026, lists HTML files on Business and above. Its public HTML viewer code, read on 14 October 2026, records the whole file as one page; HTMLRadar reports which sections each recipient read.
How much does Papermark cost compared with HTMLRadar?
Papermark’s pricing page and linked pricing data, checked on 19 October 2026, list Pro at €24, Business at €59 and Data Rooms at €99 per month billed annually. With monthly billing, those plans cost €29, €79 and €149 respectively. Business and Data Rooms include three team members; the free plan remains €0. HTMLRadar Pro is $19 a month or $190 a year for one person with unlimited tracked links, plus a free plan of two tracked links. Papermark’s free plan is far more generous on link count. HTMLRadar Pro includes a custom domain; Papermark’s pricing page, checked on 19 October 2026, lists custom domains from Business at €59 a month billed annually, or €79 with monthly billing.
Is Papermark fully open source?
Almost. Its LICENSE file, read on 14 October 2026, puts the repository under AGPLv3 with one carve-out: everything under the ee and app/(ee) directories is under a separate commercial licence. Its pricing page also lists the self-hosted option and self-hosting support as Enterprise lines.
Which should I choose for a pitch deck?
It depends on what the deck is. If it exists as a PDF or a PowerPoint and always will, Papermark will track it page by page and HTMLRadar will not. If it exists as HTML — a Claude artifact, a reveal.js build, a page you wrote — then converting it to a PDF just to track it throws away the layout and interactions you built, and HTMLRadar tracks the page as it is. If you have a PDF and want to try the HTML route, the free converter at /convert turns a landscape PDF deck into one HTML page in your browser.
Does HTMLRadar have data rooms?
No. HTMLRadar tracks one document per link, with attachments that ride along under the same link. There is no folder structure, no group permissions and no due-diligence workflow. Papermark’s pricing page and linked pricing data, checked on 19 October 2026, list Data Rooms at €99 a month billed annually, or €149 with monthly billing. The plan adds granular file permissions, NDA agreements and data-room analytics.
