The Vioscale score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Stream, not the verdict.
| Signal | Score | Weight | Contribution | Evidence |
|---|---|---|---|---|
| Reliability | 100 | 30.00 | 2998.5 | ✓ |
| Security Posture | 85 | 22.00 | 1870.0 | ✓ |
| Pricing Transparency | 100 | 12.00 | 1200.0 | ✓ |
| Capabilities | 75 | 12.00 | 896.7 | ✓ |
