Source: https://www.prefect.io/pricing
Can Prefect be self-hosted?
Yes. Prefect can be deployed cloud / SaaS, hybrid and self-hosted, so it does not have to run on the vendor's infrastructure.
Source: https://www.prefect.io/pricing
What does Prefect integrate with?
We have confirmed 12 integrations for Prefect, including Pydantic AI, OpenAI, AWS Secrets Manager, HashiCorp Vault, dbt, Slack, Snowflake and Redis, plus 4 more. This is what we could verify from public sources, so the vendor may support others we have not indexed.
Source: https://www.prefect.io/pricing
What security certifications does Prefect have?
We have independently confirmed SOC 2, HIPAA and GDPR for Prefect. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as Prefect not holding them. Always confirm compliance directly before you rely on it.
Source: https://www.prefect.io/security
Is Prefect open source?
Yes. Prefect is published under the Apache-2.0 licence, a permissive licence that generally allows commercial use and modification. Licence terms can change between releases, so verify against the repository for the version you intend to use.

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 Prefect, not the verdict.
