Productivity & Documents
If you need to write documents, build spreadsheets, or sign PDFs, you often end up with Microsoft 365 or Adobe Acrobat. This page gathers free and open-source alternatives for everyday documents — without cracks, with a link to each project’s official site — organized into three sections: office, PDF, and writing and signing.
Not every option covers advanced macros or the same add-on ecosystem as the paid suite. The curation prioritizes free and open-source programs cited in recent guides and forums. The longer guide on Word, Excel, and PowerPoint is on the blog; below is this category’s catalog.
