Reference

ElectricSQL is a conflict-free sync layer implementing active-active replication between Postgres in the cloud and SQLite on the local device. As such, it extends Postgres for strong eventual consistency and optimal scale and resiliency.

ElectricSQL is developed by a team of experienced engineers and specialist distributed database experts, under the guidance of:

• Marc Shapiro and Nuno Preguiça, the co-inventors of CRDTs
• Annette Bieniusa, the lead developer of AntidoteDB
• José Valim, the creator of the Elixir programming language

The project builds on decades of research, in many cases invented and pioneered by the core team and advisors.
