In their own words
MonetDB
MonetDB is a free, self-hosted relational database system built primarily for analytics, data warehouses, and bulk processing such as business intelligence and scientific analysis. It provides a SQL-compliant interface with keys, joins, views, triggers, stored procedures, and ACID properties for concurrent transactions, though it is not tuned for high-volume transaction processing. Its columnar storage and parallel query execution target heavy analytical workloads. Tables are vertically fragmented into columns represented as Binary Association Tables, with persistent BATs implemented as memory-mapped files. SQL user-defined functions can aggregate, filter, operate over windows, or return tables. Prebuilt packages are available for 64-bit Linux and macOS, and 32-bit or 64-bit Windows. Native interfaces cover languages including Python, Java, Node.js, PHP, R, Go, and C# .NET, and a separate ODBC installer is available. Listed integrations include Tableau, SQLAlchemy, Django, and GeoTools. Client-server communication is unencrypted by default, though TLS can be used through a termination proxy. MonetDB was founded in 2004 and is based in Amsterdam.
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.
