One operating system for the whole product development lifecycle - ideate, plan, code, ship, discuss, and document, in a single workspace shared by your team and their agents.
What is Rezee?
Rezee is one operating system for the whole product development lifecycle. Not five tools with integrations wired between them - five layers of the same workspace, nested inside each other the way the mark above suggests, talking to each other from day one.
An idea becomes a spec, the spec becomes issues, the issues become branches and pull requests, a pipeline ships them, and the conversation and the docs that explain why stay attached to all of it. Your team and their agents work those same surfaces, with the same history, the same search, and the same permissions - so there is no context switching and no work scattered across five SaaS tabs.
It runs as a managed cloud service. There is no self-hosted product: nothing to provision or maintain, your team just signs in and starts shipping.
The five layers
✏️ Ideate & Design - shape the idea before the first commit. Specs, RFCs, and design docs in a block-based editor, organized as a tree, started from templates your team owns - and a visual canvas inside the same document: diagrams, slide decks you can present full screen, and interface mocks on device frames, laid out with real sizing and built from components the workspace publishes. Share a read-only link with someone who has no account, or export a frame as PNG and a deck as PDF.
📋 Plan & Track - issues, projects, and cycles that span every repo in the workspace. Branch from an issue and the pull request links itself; merge it and the issue closes. The board is the status meeting.
💻 Code & Ship - git hosting over HTTPS and SSH, pull requests with review, approvals, and branch protection that gates merges on green CI, and CI/CD defined in
.rezee/actions.yml. Every push runs its steps in throwaway containers and streams logs to your browser.💬 Discuss & Document - channels, DMs, and threads where pull requests, issues, and commits unfurl inline with live status, next to a wiki built from the same editor. One query searches what was said and what was written.
🤖 AI & Agents - agents are workspace members, not API keys: named, scoped, revocable, and auditable. Mention one in chat or delegate a task, and you watch it work step by step - its messages, its tool calls, and the results - through the same API and MCP tools your team's surfaces use.
Agents propose. People decide.
An agent's irreversible actions arrive as proposals: merging a pull request, publishing a share link anyone can open - the task pauses, a person approves or rejects, and the decision is recorded. That gate is the product's defining bet rather than an afterthought, and every agent action lands in the same audit log as human activity, attributed to the agent that took it.
Foundations
Every layer sits on the same five: a real-time sync engine and event stream so the UI stays ahead of the work; keyboard-first navigation with a command palette for every action; command-line native, because repos, issues, pull requests and runs all drive from the rezee binary; secure by default - encrypted secrets, scoped tokens, branch protection, and repos invisible to non-members,
included on every tier rather than sold as one; and open to agents through a public API and an MCP server, so an outside agent drives the same surfaces your team does.
Getting started
Rezee is a hosted product. Create a workspace at Rezee.app, invite your team, and start shipping - there is nothing to install or run.
