mnemiq vs Outerbase AI

mnemiq is an open-source text-to-SQL engine for enterprise data agents, configured and measured against a user's own database. Before execution, a deterministic check verifies that proposed SQL is read-only, uses permitted objects, compiles in the source dialect, and passes EXPLAIN. Access permissions apply before schema retrieval, so the model is not shown tables the caller cannot access. Each answer includes the SQL run, the tables it touched, and the enrichment version used. mnemiq can profile columns and build descriptions, grain, glossary terms, and coded-value meanings; a human owner can certify semantic definitions. Listed databases are PostgreSQL, SQLite, DuckDB, Oracle, Snowflake, and Databricks, with DuckDB as the universal executor. Models can use any OpenAI-compatible /v1 endpoint, including local servers such as vLLM, Ollama, llama.cpp server, and LM Studio. Its MCP server offers two read-only, access-scoped tools: db_read(question) and get_schema(). One process can also serve a workbench and HTTP endpoints for asking, chatting, and retrieving schema. The Apache-2.0 engine is free and runs in the user's environment. Local model hosting keeps schemas, questions, and rows inside the user's network, according to the maker.

Outerbase AI is a database platform with EZQL, an assistant that turns natural-language requests into queries, charts, and dashboards. It uses the database schema as context, and its AI query editor can generate queries, repair broken ones, and optimize results. Charts can be created from datasets or within AI conversations. Connections include Postgres, MySQL, SQLite, MongoDB, ClickHouse, Microsoft SQL Server, Snowflake, Google BigQuery, and Amazon Redshift; listed provider integrations include DigitalOcean, Neon, Turso, and Cloudflare. Security features include two-factor authentication, database-role access, encryption, SSH tunneling, and private AI models not trained on customer data. Customer data stays in the customer’s database, while Outerbase stores an encrypted schema version. The free plan is free and includes up to 5 users, 1 base, 10 EZQL queries monthly, 3 saved queries, and 1 dashboard, for transactional databases only. Hobby is $9 a month and Pro is $30 a month, per user and billed annually. Desktop apps support Mac devices with M1 or newer chips and modern Windows devices. Self-hosting is available only to Enterprise customers.
