How to choose a Cosine alternative
- Test it on your real repository, not a demo one. Performance collapses on large, messy codebases in ways the marketing examples never show.
- Check where your code goes. For proprietary code, look for self-hosting, zero-retention terms or a VPC deployment, and read the data policy rather than the badge on the homepage.
- Decide the review rule before you adopt it. Agent pull requests still need a human reviewer, and teams that skip that step ship subtle regressions.
