ONLYOFFICE DocSpace

Open-source spreadsheet-database hybrid — like Airtable but self-hostable and free. Build relational tables with formulas, linked records, and custom views without monthly fees. Access rules run per row and per column, which is what usually forces teams off a plain spreadsheet.

Turn any database (MySQL, Postgres, SQLite) into a smart spreadsheet UI. The open-source Airtable alternative that works with your existing data infrastructure. It connects to an existing database rather than importing it, so the spreadsheet view and the app share one source of truth.

End-to-end encrypted office suite — docs, spreadsheets, kanban, code pads. No account needed for guest use. Hosted in France, GDPR-native. The privacy-first Google Docs alternative.

Free and Open source tool to streamline document filling and signing. Create custom PDF forms to complete and sign with an easy to use online tool. Automatic digital signature.

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.

A lightweight Firebase Progressive Web App built to notify forgetful coworkers when the office fridge is running low on milk. Designed for workplaces and shared kitchens, it sends notifications so the team restocks before the next coffee break instead of finding an empty carton.
