Project description

The declarative code-first data integration engine

Say goodbye to writing, maintaining, and scaling your own API integrations.
Unlock 600+ APIs and DBs and realize your wildest data and ML-powered product ideas.


Meltano Hub is the single source of truth to find any Meltano plugins as well as Singer taps and targets. Users are also able to add more plugins to the Hub and have them immediately discoverable and usable within Meltano. The Hub is lovingly curated by Meltano and the wider Meltano community.
