Bruin

Bruin tackles a familiar problem: getting a single trustworthy number often means stitching together half a dozen tools and paying for each one. Its answer is a single platform where ingestion, transformation, quality and governance live together. The core is an open-source CLI, Apache 2.0 licensed, in which every pipeline asset is a YAML and SQL file committed to your own repository. You can run it locally, in CI or on your own infrastructure, which means no lock-in and a review, version and rollback flow that looks like the rest of your codebase. The CLI also ships ingestion through ingestr, so bringing in data from databases, warehouses, APIs, files and streams does not require a separate connector subscription.

The AI layer sits on top and is where most of the commercial value is. Bruin's AI data analyst answers questions in the tools teams already use, including Slack, Microsoft Teams, Google Chat, WhatsApp, Discord, Telegram and email, returning both the number and the query behind it. From a prompt you can generate dashboards and lightweight data apps, and scheduled agents keep working around the clock: watching pipelines, spend and schema changes, pausing a campaign when cost exceeds plan, flagging an owner when a source API fails and re-running a backfill, or holding downstream models when a column type silently changes.

The project is popular enough to have accumulated thousands of GitHub stars and is used by data teams at game studios and e-commerce companies who report large warehouse cost reductions. For organisations that need it, Bruin Data Limited holds ISO/IEC 27001:2022 certification and SOC 2 Type 2 attestation, with role-based access, SAML single sign-on, audit logs, AES-256 encryption and VPC peering. The CLI is free to self-host forever; the cloud is where subscription pricing applies.
