daytona vs E2B
daytona is much bigger: 71.7k stars against 13.8k. Over the days we have tracked them daytona moved -0.8% and E2B +5.4%, so E2B is growing faster right now.
They split the axes: daytona leads on context depth, E2B on privacy and model freedom.
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.

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 | daytona | E2B |
|---|---|---|
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 access | ●●●●● Command-only |
Noise control How it keeps output volume down — severity thresholds, deduplication, incremental runs over new commits only. | ●●●●● Governance controls | ●●●●● None |
Customization How far it bends to your team: custom rules, prompts, style guides, per-path config. | ●●●●● Configurable builder | ●●●●● Minimal config |
Privacy Whether your code stays on your own infrastructure: fully local, self-hostable, or cloud API only. | ●●●●● Hosted cloud (API key) | ●●●●● Self-hostable |
Model freedom Whether you can point it at any provider, or it is wired to one. | ●●●●● No model freedom | ●●●●● Bring-your-own-key |
Setup ease What it takes to get a first useful run out of it. | ●●●●● API key + quick start | ●●●●● API key + SDK |
