Open-Source Model-Agnostic AI Platform

Claude’s ecosystem is compelling — unified chat, coding agent, routines, cloud runners, desktop app, iOS app — but it’s fully closed and locked to Anthropic’s models. There doesn’t appear to be a real open-source equivalent.

The gap

Existing open-source coding agents (Aider, OpenDevin, etc.) focus on the coding piece only. Nothing seems to offer the full platform: chat + coding agent + automation routines + multi-device support, in a model-agnostic, self-hostable package.

The idea

An open-source platform replicating the Claude ecosystem:

  • Chat — general-purpose assistant
  • Coding agent — file-editing agent loop (like Claude Code)
  • Routines — scheduled agent runs (like Claude Code Routines)
  • Mobile + desktop — apps for capturing and interacting
  • Model-agnostic — connects to any provider via OpenRouter; not a model provider itself
  • Deployment — self-host with your own API key, or use a managed SaaS tier with a paid plan

The SaaS tier is how it stays funded — self-hosters pay for the platform’s hosting/infra, not the model calls.

Open questions

  • Does something like this already exist? (Open-source, model-agnostic, full platform — not just a coding agent)
  • Is the SaaS tier enough of a business? Users who can self-host probably will.
  • Who builds this — a company or a community project?
