They split the axes: astron-agent leads on model freedom, kestra on noise control.
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
Enterprise-grade agentic workflow platform with built-in RPA and high-availability focus for production deployments, unlike many prototyping-focused workflow engines.

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 | astron-agent | kestra |
|---|---|---|
Context depth How much of your codebase it sees before it answers: the open diff, the diff plus related files, or the whole repository. | ●●●●● Diff only | ●●●●● Flow-level only |
Noise control How it keeps output volume down — severity thresholds, deduplication, incremental runs over new commits only. | ●●●●● No explicit controls | ●●●●● Real-time validation |
Customization How far it bends to your team: custom rules, prompts, style guides, per-path config. | ●●●●● Custom extensions supported | ●●●●● Plugins & YAML |
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. | ●●●●● Bring-your-own models | ●●●●● No model support |
Setup ease What it takes to get a first useful run out of it. | ●●●●● Docker quick start | ●●●●● One-command start |

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.
- Noise control: Real-time validation (3/5 against 1/5)
