DocuSeal

Open-source office suite with pixel-perfect DOCX/XLSX/PPTX compatibility. Self-hostable or cloud. The best free replacement for Google Docs when you need perfect Microsoft format support. Formulas, macros and track-changes survive a round trip through Office, which is where most alternatives break.

Open-source DocSend alternative — share documents with analytics. See who viewed your pitch deck and for how long. Self-hostable, no per-link fees. Links can expire or require an email, so a deck sent to one investor cannot quietly circulate to others.

Open-source, privacy-first web analytics. See your traffic without GDPR consent banners, without sending data to Google. Self-hostable, lightweight 1KB script, no cookies. The script is under 1 KB and sets no cookie, so it adds no consent banner and almost no page weight.

Open-source, self-hosted website analytics. Simple dashboard, real-time visitors, no tracking cookies. A clean GDPR-compliant Google Analytics replacement. No cookie is set and no personal data is stored, which is what removes the consent banner rather than hiding it.

The open-source web editor for slide decks — create, present, and share presentations from the browser, with live audience interaction. The project is now archived: the hosted editor is offline, but the code remains open source and self-hostable.

Online LaTeX editor with real-time collaboration. Write academic papers, theses, and technical documents in LaTeX without installing anything. The standard for academic publishing. Compilation happens server-side with a full TeX Live distribution, so a package never has to be installed locally.
