Built our open-source stack manager on Elixir

We’ve been self-hosting tools like Cal, Supabase, Formbricks, and Plane — and got tired of wiring everything together across separate repos, envs, and dashboards. So we built onestack.cloud, an orchestration layer written in Elixir, running on a single VPS.

There’s a managed version live now (Hetzner) but we’re about to open source the project so others can self-host with infra as code baked in.

The goal for the OSS version is:

• A single codebase with a central config to manage your whole stack

• One click deploys (via Docker Compose for now)

• A management layer over the top with unified credentials across all tools and simple onboarding and offboarding for teams

• Enable or disable services from config without manual infra changes

Right now we support 9 tools on the platform. The vision is to support 50+ so self-hosters and teams can pick what they need from a growing library of open source apps and manage everything from a single codebase without having to piece it all together.

It’s a bit buggy and not perfect yet but we’d really love people’s feedback.
