To do the hardest work,this needs to be open*

* We need more partners before we open-source the core,
to stabilise the code and SDK.

Lainstack is extendable with new connectors, blocks, data lake packs, and more. It is also built to be self-hostable.

One continuous open-source lineA single white line feeds a server, writes OPEN, becomes a free-as-in-beer mug, forks through a git graph, and finishes as a repository cat.

Lainstack's strategy: sustainable progress

Open source made Lainstack possible, and opening the core is how we give back. It also keeps control with you: inspect how it works, run it independently, adapt it to your operation, and keep going if our paths diverge. As an independent company, we succeed when you choose to grow with us.

AGPLv3, because sharing is caring.

We offer the core of Lainstack with some limitations to protect our own business. If you'd like to seek an Enterprise licence or want a commercial licence, go to Request early access.

  1. Run it

    Use Community for any purpose, including commercial work.

  2. Change it

    Study the source and make your own modifications.

  3. Share it

    If you distribute it, keep the licence and provide corresponding source.

  4. Serve changes

    If users interact with your modified version over a network, offer them its corresponding source.

It runs entirely in your cloud.

Lainstack is built to run inside a closed network. Whether we host it or you do, operational data stays within the deployment perimeter and the stack connects only to the systems you choose.

You'll have to wait a bit for open source.

We'll publish the core after Lainstack has been tested enough in real operations. If you'd like access before then, request early access.
