About

Cubic Echo is a small open source software outfit. The work falls into four rough piles: agent and MCP tooling, a personal cloud of self-hosted apps for one person's life, developer libraries — mostly around GraphQL — and a few standalone apps that run in a browser tab.

They lean on each other more than they look like they do. The agent servers share an agent loop and a tool pool; the personal-cloud apps each serve their own GraphQL API and are stitched into one page by the dashboard; the apps share components and a site kit. When the same thing gets written three times, it becomes its own repo — that is most of the Dev Tools list.

For now, Cubic Echo is run by a single developer. The work is unified by a preference for small, sharp tools, public source, self-hosting over accounts, and projects that scratch a real itch.

Everything is on GitHub, and every project has its own README; several have their own site too.
