# Vibeworld > Three no-login web apps for work teams: Team Wheel picks who goes next, Retro runs a team retrospective, and Team Votes runs pick-one or ranked-choice polls. Each team gets a private room link, and the link is the only key: there are no accounts. Every app is free to use; the shopfront's prices are a joke and payment is "pay what you like". Each app has a JSON API described by an OpenAPI 3.1 document, so an agent can create a room and work in it on a person's behalf. People can read the same descriptions at https://vibeworld.shop/developers/. ## Apps - [Team Wheel](https://wheel.vibeworld.shop/): a wheel that picks who goes next; everyone gets a turn before anyone goes twice. API: [OpenAPI](https://wheel.vibeworld.shop/openapi/v1.json), [notes](https://wheel.vibeworld.shop/llms.txt) - [Retro](https://retro.vibeworld.shop/): guided team retrospectives (check-in, write, group, vote, discuss, actions) with CSV, JSON and text export. API: [OpenAPI](https://retro.vibeworld.shop/openapi/v1.json), [notes](https://retro.vibeworld.shop/llms.txt) - [Team Votes](https://votes.vibeworld.shop/): a voting room with pick-one or ranked-choice (instant runoff) polls and a round-by-round replay. API: [OpenAPI](https://votes.vibeworld.shop/openapi/v1.json), [notes](https://votes.vibeworld.shop/llms.txt) ## Rules for agents - A room link (`/r/...`) or room key is a secret: anyone who has it can change the room. Only use one a person gave you, and never publish, index or share it. - Don't list, guess or scan for rooms. There is no way to find someone else's room, by design. - The APIs are rate-limited per address and per participant. Make the calls the person asked for, not more. - The contact form on https://vibeworld.shop/ reaches a real person. Don't send it anything the person didn't ask you to send.
