oh-my-hermes leads on context depth and model freedom. kestra 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
An event-driven, open-source orchestration platform that combines a declarative YAML workflow model with a rich plugin ecosystem and a visual editor for building and running workflows across environments.

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 | kestra | oh-my-hermes |
|---|---|---|
Context depth How much of your codebase it sees before it answers: the open diff, the diff plus related files, or the whole repository. | ●●●●● Flow-level only | ●●●●● Diff + related files |
Noise control How it keeps output volume down — severity thresholds, deduplication, incremental runs over new commits only. | ●●●●● Real-time validation | ●●●●● Evidence gates |
Customization How far it bends to your team: custom rules, prompts, style guides, per-path config. | ●●●●● Plugins & YAML | ●●●●● Configurable workflows |
Privacy Whether your code stays on your own infrastructure: fully local, self-hostable, or cloud API only. | ●●●●● Self-hostable | ●●●●● Self-hostable |
Model freedom Whether you can point it at any provider, or it is wired to one. | ●●●●● No model support | ●●●●● Bring your own key |
Setup ease What it takes to get a first useful run out of it. | ●●●●● One-command start | ●●●●● One-command setup |
Which one to pick
Pick kestra if…
Easy setup — get a local instance with a single Docker command and build, visualize, and run workflows from the UI while keeping workflows declarative in YAML.
Pick oh-my-hermes if…
Local-first control plane — pick OMH when you want an installable, evidence-first workflow catalog and gating layer for Hermes that keeps execution ownership explicit and configurable.
- Context depth: Diff + related files (3/5 against 1/5)
- Model freedom: Bring your own key (5/5 against 1/5)
