In their own words
Firestore
Firestore is a fully managed, serverless document database for building AI, web, and mobile applications. It stores flexible JSON data and supports vector search, full-text search, geospatial queries, and ACID transactions on JSON or BSON-compatible documents. Client SDKs for Android, iOS, and web provide real-time updates and automatic syncing for offline access. Firestore can replicate data across multiple regions with strong consistency; multi-region deployments have a stated 99.999% SLA-backed availability. Integrations named for generative AI application work include Google AI Studio, remote MCP, LangChain, and LlamaIndex. Identity controls connect with Cloud IAM, Cloud Identity Platform, and Firebase Authentication. Data is encrypted before it is written to disk, with customer-managed keys available through Cloud KMS. The free quota applies to one database per project and includes 1 GiB of storage, daily read, write, and delete allowances, and 10 GiB monthly outbound transfer. New customers receive $300 in credits, separate from that quota. Server client libraries bypass Firestore Security Rules, so server access needs IAM controls.
SingleStore Helios
SingleStore Helios is a cloud database service available on AWS, Google Cloud, and Microsoft Azure. It handles transactional and analytical workloads in one database, with storage and compute scaled independently. Its data capabilities include relational records, JSON/BSON documents, vector and full-text search, time-series, geospatial, and key-value data. SingleStore Pipelines can ingest from sources such as Kafka, Amazon S3, and HDFS. For AI workloads, the service includes Jupyter notebooks, data integration services, and a compute service. Listed integrations include Datadog, Terraform, Apache Spark, AWS Glue, Azure Data Factory, dbt, and Fivetran. Helios is available through web and API platforms. The free Shared plan provides one workspace for evaluation, development, and non-production testing, with self-support. Standard is $0.99 a month for managed production workloads, with read replicas, database branching, 30-day monitoring, and support. Enterprise is $1.49 a month and adds online point-in-time recovery, Smart Disaster Recovery, audit logging, and customer-managed encryption keys. The listed availability commitments vary by configuration, reaching 99.99% across two availability zones on paid plans.
