Cosmo Studio
Open-source desktop AI workspace for multiple models, ACP agents and MCP tools.
The founders
The company
Cosmo Studio builds Cosmo, an open-source desktop workspace that puts multiple AI models, ACP agents and MCP tools in one place across macOS, Windows and Linux. Users bring their own API keys for providers like OpenAI, Anthropic, Gemini, xAI, Mistral and DeepSeek, or point it at local servers such as Ollama and LM Studio.
Teams are juggling a sprawl of AI subscriptions, agents and tools with little visibility into cost or control over data. Cosmo's bet is that a local-first, bring-your-own-key workspace — with chat history kept on-device — is what the next wave of power users actually wants.
The company was founded in 2026 by Gaurav Saini to tackle the fragmentation of working across many models, agents and tools at once. Beyond that, the founding team's pedigree isn't yet public.
Shipping a cross-platform desktop app that speaks to six-plus cloud providers, local model servers, MCP and the ACP registry is a serious engineering surface. The founding team has chosen to build it in the open, which is one way to earn trust in a trust-sensitive category.
