Source: https://www.skylight.io
Can Skylight be self-hosted?
We have only confirmed a cloud / SaaS deployment for Skylight, so it appears to be vendor-hosted. If a self-hosted option exists we have not found it documented publicly.
Source: https://www.skylight.io
What does Skylight integrate with?
We have confirmed 9 integrations for Skylight, including Sidekiq, DelayedJob, ActiveJob, Sinatra, Grape, GraphQL, MCP and GitHub, plus 1 more. This is what we could verify from public sources, so the vendor may support others we have not indexed.

What security certifications does Skylight have?
We have independently confirmed GDPR for Skylight. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as Skylight not holding them. Always confirm compliance directly before you rely on it.

The vioscaleAI 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 Skylight, not the verdict.
