The desktop workspace where AI agents write code in parallel — and you lead the team.
Traditional IDEs are editor first — you type, the AI assists. Onward flips this around.
In Onward, agents do the coding. You plan the work, dispatch prompts, and review what they built. The editor is there when you need it, not as the starting point.
This is for developers who run multiple AI coding agents (Claude Code, Codex ...) and need a single workspace to orchestrate them all.
The left-side Prompt Manager is where you compose, organize, and schedule the work your agents will do.
This is the key differentiator from VS Code or single-agent tools: you manage what to do separately from who does it, enabling true parallel orchestration.
Onward natively supports running multiple AI agents side-by-side, each in its own terminal window.
Agents write code in parallel. You stay in control.
After agents finish writing code, you need to review what changed. Each task gets its own integrated editor with full inspection capabilities.
One workspace per task. Complete visibility into what every agent did.
