Meltano: Pricing, Features & Alternatives

Meltano treats data pipelines like software: connectors are Singer taps and targets declared in a YAML project you keep in Git, run from the CLI or any scheduler you already operate. There is no hosted bill because there is no hosted product to buy — you run it on your own infrastructure, which is the point for teams that would rather own the pipeline than rent it.
