oh-my-openagent leads on context depth and customization and model freedom and setup ease. symphony does not take any axis by a clear margin.
Stars and commit dates come from our own daily tracking. The six axes are read off each project's documentation by our review pipeline, so they describe what a project says about itself, not what we measured in its code.
Where they stand today
Orchestrates multiple agent harnesses and parallel "discipline" agents (Team Mode) to run whole-repo autonomous workflows rather than a single-model single-agent approach.

Six axes, head to head
Each axis runs 0 to 5. The label under a score is what that project's own docs claim, not a category average.
| Axis | oh-my-openagent | symphony |
|---|---|---|
Context depth How much of your codebase it sees before it answers: the open diff, the diff plus related files, or the whole repository. | ●●●●● Whole-repo analysis | ●●●●● Diff + related files |
Noise control How it keeps output volume down — severity thresholds, deduplication, incremental runs over new commits only. | ●●●●● Basic filters | ●●●●● Human acceptance gating |
Customization How far it bends to your team: custom rules, prompts, style guides, per-path config. | ●●●●● Config + plugins | ●●●●● Minimal config |
Privacy Whether your code stays on your own infrastructure: fully local, self-hostable, or cloud API only. | ●●●●● Cloud APIs (your key) | ●●●●● Self-hostable |
Model freedom Whether you can point it at any provider, or it is wired to one. | ●●●●● Multi-provider / BYOK | ●●●●● Fixed provider |
Setup ease What it takes to get a first useful run out of it. | ●●●●● One-command install | ●●●●● Manual setup required |
Which one to pick
Pick oh-my-openagent if…
Multi-provider orchestration — choose this when you want an open, extensible agent harness that coordinates many models/agents for complex, whole-repo automation and installs quickly via a one-line command.
- Context depth: Whole-repo analysis (5/5 against 3/5)
- Customization: Config + plugins (4/5 against 2/5)
- Model freedom: Multi-provider / BYOK (5/5 against 1/5)
- Setup ease: One-command install (5/5 against 3/5)
Pick symphony if…
Self-hostable — use Symphony when you want an on-prem orchestration that spawns isolated agent runs, produces PRs and CI proof-of-work, and reduces hands-on agent supervision.
