What's the story behind your product?

Synopedia's answer

Synopedia started as a side project by an independent web publisher in France who was tired of synonym sites buried under ads and mixed-up word lists.

The idea was simple: build a clean, fast thesaurus using only open data, then make it useful across languages, since many people write in more than one. The French version came first, followed by Italian, Spanish, German, Catalan and English.

Which are the primary technologies used for building your product?

Synopedia's answer

  • PHP 8.4 (no framework), with fully server-rendered HTML
  • SQLite, one read-only database per language
  • Python for the offline data pipeline that builds and ranks the synonym data
  • Open data sources
