Estuary Flow
iScoreA streaming ELT platform billed per gigabyte moved plus a flat monthly fee for each connector instance, with millisecond latency on the entry paid plan.
Who it suits
Pipelines that have to be fresh. Millisecond latency or batch is included on the entry paid plan at no extra charge, where the other three gate sub-15-minute syncs behind a higher tier or a sales call. The free tier runs indefinitely at 10 GB a month with no card.
Consider something else if…
You need the compliance paperwork or a lot of pipelines. SOC 2 and HIPAA reports, SSO and any SLA at all are Enterprise-only, and no availability figure is published anywhere. The per-instance fee compounds: a pipeline is two connector instances, so three of them is $600 a month before a byte moves.
