IndieWeb Alignment
Otso builds on IndieWeb protocols and encourages publishing on your own domain first.
Principles embraced
Section titled “Principles embraced”- Own your data – everything lives in a local database you control.
 - Publish first – your site is the source of truth; POSSE pushes copies out.
 - PESOS optional – you can import from silos without surrendering ownership.
 
Protocol support
Section titled “Protocol support”- Micropub for publishing.
 - Webmention for replies, likes, and reposts.
 - Microformats2 for semantic HTML.
 
Extending the IndieWeb
Section titled “Extending the IndieWeb”By keeping sources, enrichments, and publishing logic pluggable, Otso allows experimentation while staying interoperable with existing IndieWeb tools.
