SingleStore

Developed by SingleStore, this distributed SQL database handles combined transactional and analytical workloads, plus vector and multi-model data. The company's own description is a real-time database for AI, apps and analytics. SingleStore was formerly known as MemSQL.

One engine for transactions and analytics

The pitch is a single engine with live reads and writes, so analysis can run on current data instead of a copy moved to a separate system. The company is headquartered in San Francisco, has venture backing and counts large enterprises among its customers, in sectors like financial services, media and energy.

Ways to buy

Customers can buy SingleStore as the Helios Cloud service, as software they manage themselves, or as a bring-your-own-cloud arrangement. Published pricing includes a free Shared Workspace tier, intended for evaluation and for work outside production. Standard and Enterprise editions are billed by the hour, and new accounts receive free credits.

Releases

The documentation points to Self-Managed version 9.0 by default, and no newer 9.x release was seen. Posts on the vendor blog dated September 2026 cover agent features: query tuning, observability and an analyst feature.

Points to confirm

Because the free tier only covers work outside production, live workloads need a paid edition. Buyers should confirm the license terms and current release number with SingleStore before committing to a deployment.
