Open Source · Apache 2.0

LeastAction Lite.
The whole platform, open.

Same catalog, same AI operator, same marketplace as the commercial edition — released under Apache 2.0. Multi-user, no seat cap. Self-host it, modify it, use it commercially.

Why it exists

We research, we build.

LeastAction started from years of building data platforms at scale — internal tools at AWS, warehouse orchestration for large teams, the shape of what breaks when the AI writes the code. The core is what we’d want to use ourselves. We open-sourced Lite because the ideas are worth trying in public, and because a paid enterprise tier is what lets us keep the research going.

What’s inside

The whole stack.

The full catalog — operators, actions, connections, payloads, skills, usecases
The AI operator that generates, runs, and repairs pipelines
MCP server (~25 tools) for Claude Code and any MCP client
`inspect_data` across Postgres, MySQL, Athena, Redshift, BigQuery, S3, GCS
Community marketplace — import and publish
Multi-user, no seat cap
Docker Compose install, Blue-Green production deploy
Install

Docker Compose. Three minutes to a running pipeline.

Terminal~3 min
git clone https://github.com/LeastAction-Labs/LeastAction-Lite.git
cd LeastAction-Lite

docker compose up -d --build

# open http://localhost:8080
# default login: admin@example.com  /  admin123

Bundles a dbt runner, demo Postgres, and a seeded workflow that starts running on its own. For production, use ./blue-green-run.sh --fresh— two-slot swap with automatic rollback on failed health.

How to engage

Async, GitHub-native.

No Slack, no Discord. GitHub Discussions goes live when the Lite repo does. Until then, four low-friction paths in.

Paid tier

The Enterprise Edition — source-available.

Groups, item-level permissions, SSO/SAML, private marketplace, managed hosting. Source-available under the Enterprise Edition License — code is open to read; running it commercially needs a license. Same catalog. License flip, no migration.
