HRA vs OpenChamber
Both provide a visual place to start, supervise, and revisit agent work while the actual coding process runs on a developer-controlled machine.1346789
Short answer
Choose for the job in front of you.
Choose OpenChamber
Choose OpenChamber for a visual OpenCode workflow across macOS, Windows, Linux, browser, and mobile beta, including worktrees and scheduled tasks.6789
Choose HRA
Choose HRA when your runtime is Codex and you need several authorized Codex accounts to participate in one durable, recoverable task graph.134
The meaningful difference
The products put authority in different places.
OpenChamber is an interface and workflow layer around OpenCode, with broad desktop, browser, remote, worktree, goal, and schedule surfaces. HRA uses Codex directly and makes durable account identity, delegation, model intent, and effect reconciliation its center.1346789
Side by side
The decisions that matter.
| Decision | HRA | OpenChamber |
|---|---|---|
| Core job | Coordinate a Codex workload with durable authority.13 | Give OpenCode a visual, multi-device working environment.67 |
| Runtime | OpenAI Codex app-server.23 | OpenCode and its provider/agent model.6 |
| Platforms | Apple Silicon Mac execution with a bounded hosted view.24 | macOS, Windows, Linux, browser/PWA, and native mobile beta.67 |
| Work structure | Persistent roots, children, dependencies, leases, submissions, and review.14 | Sessions, worktrees, goals, GitHub flows, and scheduled tasks.897 |
| Account coordination | Several authorized Codex identities with local isolation.24 | Inherits OpenCode provider authentication; multi-Codex identity routing is not its documented focus.6 |
| Best fit | Deep Codex-only orchestration and recovery.13 | A cross-platform visual environment for OpenCode sessions.6 |
What HRA cannot do yet
Current HRA limitations.
- HRA's native host currently supports Apple Silicon Macs only.
- The downloadable app is ad-hoc signed, not Developer ID signed or notarized.
- The recursive harness is experimental, and the adaptive optimizer cannot activate policy.
- HRA is Codex-only; it is the wrong choice when provider breadth is the requirement.
- Multiple accounts must be owned or authorized by you and permitted to access the same work.
