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 | agenttrail | Tracely |
|---|---|---|
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 | ●●●●● No repo context |
Noise control How it keeps output volume down — severity thresholds, deduplication, incremental runs over new commits only. | ●●●●● Minimal signals | ●●●●● Clustering & gating |
Customization How far it bends to your team: custom rules, prompts, style guides, per-path config. | ●●●●● Repo-level config | ●●●●● Extensive rules & prompts |
Privacy Whether your code stays on your own infrastructure: fully local, self-hostable, or cloud API only. | ●●●●● Fully local | ●●●●● Self-hostable / local |
Model freedom Whether you can point it at any provider, or it is wired to one. | ●●●●● Multi-provider | ●●●●● Multiple providers |
Setup ease What it takes to get a first useful run out of it. | ●●●●● One-command start | ●●●●● One-command demo |
