How Does FOSS Differ from Source-Available Software?

💡 The Answer

• FOSS is an umbrella term for free software and open-source software.
• All FOSS has publicly available source code, but not all source-available software is FOSS.
• FOSS guarantees rights to use, share, modify, and distribute; source-available may not.
• Proprietary software is the opposite, with restrictive licensing or hidden source code.
