Guides for running coding agents together
How side-by-side agent tabs, task boards, and honest delivery work in practice, plus product notes as the free preview ships.
Naturally Autonomous: Why Agents Should Organize Themselves
Harmony is built on a simple thesis: agents should behave like people working together, not software following scripts. Here's the idea behind the design.
Why the IDE Had to Be Reinvented
VS Code gave us a home for a person and a file. Cursor bolted an agent onto a fork of it. But a fleet of agents doesn't fit inside an editor; it needs a new base layer.
The Terminal Is the Original Operating System
Before windows and icons, the terminal was how you told a computer to do anything. Harmony takes that primitive and puts a fleet of agents behind it.
Agentic Engineering Is a New Discipline
Prompting is not the skill. Conducting a fleet of agents, decomposing, delegating, verifying, and steering, is. Here's what that practice looks like, and what it needs from a tool.
Ralph Loops. Bart Orchestrates.
Simple loops work until they don't. Large projects need an orchestrator that can observe, steer, and adapt. Meet Bart.
The Ultimate Spec-Driven Development Approach
Epic Mode turns scattered intent into a living system of mini-specs, tickets, and built-in verification, so agents stop guessing and start shipping on real codebases.
Epic Mode: Turning Intent to Code
A first look at how Epic Mode carries an idea from a single sentence to a merged change without losing the why along the way.
The Sum Is Greater Than the Parts: Inside Harmony's Multi-Model Architecture
No single model is best at everything. Inside the ensemble of specialist LLMs that powers Harmony's planning, context-gathering, and verification.
Build With Intent, Ship With Confidence
Software isn't a sidewalk, it's a city. Harmony brings planning and verification rigor to AI-driven development so you ship with intent, not vibes.
What's next
Close the window. Come back to the work.
Quit the UI and local agent sessions keep running in the background. If the laptop sleeps, they pause with the machine; on wake, Harmony rechecks them and reattaches the same tabs and terminal history.
