Looking for an open source text expander? PhraseVault® is a source-available desktop text expander for Windows and macOS. The full source code is available on GitHub for inspection, building, and auditing. This page explains what "source-available" means and how PhraseVault compares to fully open source alternatives like Espanso.
Source-Available vs Open Source
It is important to be transparent about this distinction. PhraseVault's code is publicly available on GitHub — anyone can read, build, and audit it. However, PhraseVault does not use a permissive OSI-approved open source license. This means you can verify what the software does, but the code is not free to redistribute or modify for commercial purposes.
Espanso, by contrast, is released under the GPL license and is fully open source in the traditional sense.

Where Espanso Excels
Espanso is a genuinely open source project with a strong community. It supports Linux in addition to Windows and macOS. Its regex-based triggers offer powerful pattern matching. Shell extensions allow snippets to execute system commands and insert dynamic output. The Espanso Hub provides a community-driven package repository for sharing snippet collections. For users comfortable with command-line tools and YAML configuration, Espanso is a capable and flexible solution.
Where PhraseVault Stands Out
PhraseVault provides a graphical interface that requires no configuration files or terminal usage. Snippets support Markdown and HTML formatting out of the box. Team sharing works through a shared folder without requiring all team members to manage config files. The source-available model means you can audit the code while also receiving commercial support and guaranteed maintenance. For users who prefer a visual, ready-to-use tool with professional support, PhraseVault fills a different niche.
