Couchbase Capella review
A flexible managed NoSQL service with a free tier and clear hourly upgrades.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Couchbase Capella is a fully managed, multicloud NoSQL database service for teams building and operating modern applications. It stores JSON documents, supports key-value access and SQL++ querying, and adds search, indexing, ACID transactions through SQL++, role-based access control, scopes and collections, backups, vector search, and REST and management APIs. App Services extends the offering to mobile and IoT synchronization. The service is operated in the cloud and is available through web and API access, making it a fit for application development, transactional workloads, search, AI applications, and synchronized device data.
Pricing is consumption-based by node and hour. The Free plan includes SQL++, key-value access, search, mobile App Services, RBAC, scopes and collections, one node, 8 GB, and forum support. Basic starts at $0.15 per node per hour and adds indexing, a single-cluster availability zone, XDCR, 24-hour backups, Analytics, Eventing, and vector search. Developer Pro is $0.35 per node per hour, with multiple cluster availability zones, three nodes, backups at up to one-hour intervals, 8-hour response, 24x7 support, and a 99.99% uptime SLA for multi-node clusters. Enterprise is $0.49 per node per hour and adds auditing, customer-managed encryption keys, a three-node minimum, a 30-minute response, 24x7 support, and a 99.99% uptime SLA.
Capella’s main distinction is the breadth of capabilities around JSON application data. Search and indexing sit alongside SQL++ queries, transactions, vector and semantic search, and managed backups and restores. Integrations with LangChain, LlamaIndex, and OpenAI embeddings support AI-oriented application patterns. The trade-off is that operating cost depends on cloud provider, region, node size, storage, and data transfer, while the free tier remains a one-node, 8 GB option. Choose Capella for managed JSON and key-value workloads that may grow into search, vector, mobile, or IoT use cases; choose an alternative if those capabilities and cloud-based consumption pricing are unnecessary.
