Blink Labs and TxPipe each run a full, idempotent copy of the Demeter stack behind health-checked load balancing. Either provider can serve a request, keeping applications moving when one operator is unavailable.
Monitoring, security patches, and version upgrades are handled by the operators.
Multi-tenant services scale with traffic, with reserved throughput when production workloads need it.
The hosted APIs use open-source software and public interfaces you can run yourself.
