Mercur

You've outgrown
your marketplace builder

Sharetribe launches you in a day. When you outgrow a hosted builder, Mercur is the engine you own – full source, on your infrastructure, extend anything.

Open sourceYour infrastructureZero GMV fees

With Sharetribe, you keep the storefront and rent the engine

Sharetribe only open-sources the storefront template. The backend and APIs that run your marketplace stay proprietary and hosted. With Mercur, the whole engine is yours.
