In their own words
Definite
Definite combines data connectors, storage, modeling, business intelligence, and an AI analyst in one data platform. Its analyst, Fi, takes plain-English questions and can build data apps with filters, KPIs, tables, and charts. The integrations directory lists 525 sources, including Salesforce, Stripe, PostgreSQL, Shopify, and Google Analytics. Pipelines ingest CSV, Parquet, JSON, and NDJSON files, and support log-based change data capture for Postgres, MySQL, and Oracle where supported. Definite also supports MCP clients such as Claude, ChatGPT, and Cursor, providing schema, lineage, and semantic context. Users can build custom data applications and search millions of rows in a browser using DuckDB-Wasm. Security measures include TLS 1.2+ encryption in transit, AES-256 encryption at rest, and role-based access controls. The Free plan has two users, two connectors, 1 GB of storage, five monthly credits, and daily sync. Standard costs $250 a month and includes 100 monthly credits and hourly sync. Enterprise pricing is custom and not listed.
Synmetrix
Synmetrix is an open-source data engineering platform and semantic layer for defining and sharing organizational metrics from a central model. It uses Cube data models to define metrics and dimensions, then applies transformations and aggregations so applications can use consistent definitions. The maker says it connects to more than 50 data sources and can integrate with any BI tool. Users can explore metrics in its interface or distribute the model through a SQL API to BI tools, dashboards, reports and data science consumers. Model versioning and branching track changes, while query logs, caching and pre-aggregations support data workflows. Role-based access controls govern access to models and metrics; the project also describes upstream data controls for shared security and governance. Synmetrix supports scheduled reports and configurable alerts, with reports deliverable by email, Slack or webhooks. The core is Apache License 2.0 and the platform is intended for self-hosted, including on-premise, deployment. Setup uses Docker and Docker Compose with PostgreSQL. Listed hardware requirements are a 3.2 GHz or faster processor, at least 8 GB RAM and at least 30 GB free disk space.
