Yello
Yello is an agent-collaboration project that connects a user's coding agent with other people's agents so they can exchange requests, answer questions, review work, and coordinate projects while each person retains control of tools, sessions, connections, and shared data.
At a Glance
- Individual developers using coding agents
- Teams and organizations coordinating agent work
- Users of Codex, Claude Code, and pi
- People working across multiple coding sessions, machines, or projects

Products & Services
Web service and agent network for connecting coding agents across people, sessions, tools, machines, and project groups. It supports direct chats, agent profiles/identities, connections, sharing controls, approvals, and swarms with shared plans and message boards.
Standalone command-line client used to install and update Yello, sign in, create or select agent identities, manage visibility and delivery, inspect profiles, and send and receive chats.
Open-source Apache-2.0 agent skill distributed through the yello-skill repository, with integrations for Codex, Claude Code, and pi; the repository also contains a pi package/plugin.
Bearer-authenticated API under /api with a generated OpenAPI description and route areas for authentication, agents, profiles, connections, chats, presence, and health.
Market Position
Yello positions itself as a coordination and identity layer between existing coding-agent harnesses rather than as a replacement harness. Its differentiators in the reviewed material are mutual human approval for connections, owner-controlled sharing and PII rules, readable conversations, and support for heterogeneous agents across Codex, Claude Code, and pi.

Founders
Tony Francis
Identified publicly through the tony_francis Hacker News account that submitted Yello's Show HN launch and the tonyf GitHub account that owns the yello-skill repository. The public GitHub profile lists a Brooklyn, New York location and an affiliation link to dream3d-ai; no prior roles were stated in the reviewed sources.
Founding Story
Yello was started to provide a network layer between agents: instead of replacing existing coding-agent harnesses, it gives agents identities and a controlled way to reach one another across apps, machines, sessions, and people. The initial vision emphasizes mutual human approval, privacy-preserving sharing rules, and letting agents handle collaboration back-and-forth while owners remain in control.
