Promethium
Promethium's Instant Data Fabric gives natural-language, self-service analytics over distributed enterprise data without moving it. Its Universal Query Engine runs a single SQL query across Snowflake, Databricks, Oracle and Postgres at once, and its Mantra 'data answer agent' returns trusted answers from plain English. Mantra is in private preview; enterprise, quote-based pricing.

Our take
Promethium tackles the real headache behind text-to-SQL: data scattered across warehouses. Its zero-copy Universal Query Engine spans Snowflake, Databricks and Oracle in one query, and the Mantra agent answers in plain English. The agent is still private preview and pricing is quote-only, so it is one to pilot rather than buy off the shelf today.
Best for
Enterprise data teams that want governed, natural-language self-service analytics across multiple warehouses and databases without first building ETL pipelines to move the data.
Pros
- Zero-copy federated query across many sources at once
- Natural-language analytics via the Mantra data agent
- Unified catalog over Snowflake, Databricks, Oracle and more
- Avoids ETL data movement for cross-source questions
Cons
- Mantra data agent is still in private preview
- Enterprise, quote-only pricing with no public tier
- Value depends on already-governed source systems
How it compares
Against single-warehouse agents like Databricks Genie or Snowflake Cortex Analyst, Promethium's claim is cross-source breadth - one query and one agent over many systems - rather than going deep in one vendor's stack.
Full review
Promethium's Instant Data Fabric is built to deliver self-service analytics at AI scale without the usual ETL. Instead of copying data into a warehouse first, it offers real-time, zero-copy access across cloud, on-premises and SaaS sources, with a Data Explorer that catalogs assets spanning Snowflake, Databricks, Oracle, SAP and Salesforce. Its Universal Query Engine can run a single SQL query across several of those systems at once, resolving schemas and pushing filters and joins down to each source.
On top sits Mantra, a 'data answer agent' that lets teams ask questions in plain English and get trusted, governed answers back - the natural-language layer most enterprises actually want. The catch is that Mantra is currently in private preview, and Promethium sells to enterprises on quote-based pricing with no public tier, so the practical path is a scoped pilot. Its real differentiator is breadth across sources rather than depth in any one vendor's stack.

Langfuse
Langfuse is an open-source AI engineering platform for building and operating LLM applications. It brings together observability and tracing, evaluations, prompt management, datasets, an annotation workflow and a prompt playground, and integrates with OpenTelemetry, LangChain, the OpenAI SDK, LiteLLM and more. A Y Combinator (W23) company, it moved every product feature to the MIT license in 2025, so the only commercial pieces are thin enterprise-compliance add-ons such as SCIM, audit logs and project-level RBAC. The cloud free tier covers 50,000 units a month, with a $29/month Core plan for production traffic and higher tiers for longer retention and SOC 2/ISO reports. In January 2026 ClickHouse acquired Langfuse and publicly committed to keeping the MIT license and avoiding new pricing gates.
