WrenAI puts a semantic layer in front of your databases so questions can be answered in SQL that respects definitions your team agreed on, with the model reached on your own credentials and 22-plus connectors for the data side. The engine in the repository, covering the semantic layer, text-to-SQL, MCP server, CLI and connectors, is Apache-2.0 and self-hostable including air-gapped; a cloud and an enterprise tier are sold separately. Licensing is per-path rather than one blanket grant, which GitHub reports as unlicensed: the LICENSE file was read directly to establish that core, SDK, skills, examples and root files are Apache-2.0 and documentation is CC BY 4.0.

Why this trust score (83/100)

Trust measures how the tool treats your API key and how much of that has been verified. It contains no popularity signal.

  • Key Safety 21/25: The key lives in a deployment you run yourself.
  • Request Routing 17/20: Requests go straight from you to the AI provider.
  • Transparency 20/20: Source is public under Apache-2.0 (multi-licensed per path), so anyone can check how the key is handled.
  • Privacy 14/15: Local-first: it works without sending your data anywhere. Can be self-hosted, so the data path stays inside infrastructure you control.
  • Maintenance 10/10: Actively developed, with commits within the last three months.
  • Verification Confidence 1/10: Compiled from public documentation by an AI-assisted pass, not independently confirmed.

How your API key is handled

You self-host the app, so your API key lives in your own deployment. Requests are sent directly to the AI provider. Because it can be self-hosted, your key never has to touch a third-party backend.

Setup

Deploy it (Docker/compose), add your provider API key in the admin or environment config, then select models.
