ZeroClaw pros
- Open source with transparent code and flexible deployment options.

- Strong privacy story for users who care where data runs.
Viktor cons
- Closed-source offering, so portability and vendor transparency are limited.
- Privacy controls are limited compared to self-hosted alternatives.
- Channel coverage is narrow, so distribution options are constrained.
ZeroClaw cons
- Trade-offs are moderate rather than severe, but it does not stand out sharply on every dimension.
Viktor gotchas
