Nothing to host
No servers, no chat UI to build. Connect an agent and send your team one link.

Share your managed agents with your team
Build on OpenAI Agents or Claude Managed Agents. Melony gives your team a hosted chat with membership and sharing built in. Your key never leaves the server.
Connects to the agent platform you already use.
How it works
From a built agent to a team that uses it
Build on your platform
Create your agent in OpenAI Agents or Claude Managed Agents. Your model, instructions and tools stay there.
Connect it to Melony
Add the agent and its API key. Melony hosts the chat and lets you add up to three teammates; the key stays server-side.
Chat and share
Start a private chat, then share it with everyone on the agent when it’s useful.
Where it fits
A front door, not another agent builder
Your platform runs the agent. Melony sits between it and your team, with the chat, the roster and the key.
Simple by design
Built for the agent owner
You decide who gets in. Melony makes sure nobody gets more than they should.
- Your keyStays server-side. The owner’s API key is kept on Melony’s server and never returned to teammates’ browsers.
- Your chatsPrivate by default. Only the person who started a chat can see it until they share it with the agent’s team.
- Your platformRuns the agent. Melony keeps the chat list and session access, not message history. The conversation, model and tools stay with OpenAI or Anthropic.
- Your teamInvited by email. Add up to 3 teammates per agent as admins or members. They sign in with Google and join automatically.
Platforms
Works with the platform you already use
Melony connects to exactly two hosted agent platforms, where the platform owns the agent. Pick yours to see how it fits.
- Melony for OpenAI Agents
OpenAI Agents API
Connect an agent from platform.openai.com/agents. Optionally run sessions in the OpenAI-hosted sandbox and attach a Vault by ID.
- Melony for Claude Managed Agents
Claude Managed Agents
Connect a Managed Agent from the Claude Console, pick the environment sessions run in, and attach a vault by ID.
Control
Your agent, shared on your terms
Shared on purpose
Share a chat with everyone on the agent in one click. Only its creator can unshare or delete it.
No owner backdoor
The agent owner can’t open other people’s private chats. Private means private.
Clear roles
Owners hold the key. Admins manage the roster. Members chat. Nobody else sees the key.
Fair limits
100 messages per person per day, enforced on the server, so one teammate can’t run up the bill.

Questions
What is Melony?
Melony is a hosted, shareable chat UI for agents you have already built on the OpenAI Agents API or Anthropic’s Claude Managed Agents. You connect the agent with its API key, invite teammates by email, and everyone chats with it in one place. Melony is not an agent builder: the model, instructions and tools stay on the platform.
How do I share an OpenAI or Claude agent with my team without sharing my API key?
Connect the agent to Melony once as its owner. The key is stored on Melony’s server and is never sent to a browser, so teammates sign in with Google and chat with the agent without ever seeing the key.
Is Melony free?
Yes, Melony is free to use. You pay your agent platform (OpenAI or Anthropic) for usage on your own API key as usual. Each agent can have up to 3 teammates besides the owner, and each person can send up to 100 messages per day.
Does Melony store my conversations?
No. Messages, tool calls and memory stay on OpenAI or Anthropic. Melony keeps only a small access index of session IDs and who may see them, because neither platform has per-user session lists.
Can teammates see each other’s chats?
Only if you share them. Every new chat is private to the person who started it. They can share it with everyone on the agent, and only they can unshare or delete it. The agent owner has no backdoor into private chats.
Which agent platforms does Melony support?
Exactly two hosted agent platforms: the OpenAI Agents API and Anthropic Claude Managed Agents. Self-hosted frameworks and custom endpoints are intentionally not supported.
