Alternatives / Vanta
Looking for an open source Vanta alternative? We compared 4 open source compliance and AI governance platforms by license, frameworks, self-hosting, and open-core limits. They automate evidence and controls for frameworks such as SOC 2 and ISO 27001, and two of them are not fully open source.

| Alternative | Best for | License |
|---|---|---|
| Probo | Open-source compliance program under MIT | MIT |
| Openlane | Controls and evidence automation under Apache-2.0 | Apache-2.0 |
| Comp AI | AI-driven compliance (open core) | AGPL-3.0 + commercial parts |
| VerifyWise | AI governance for the EU AI Act (source available) | Business Source License 1.1 (source available) |
We looked for open-source tools that overlap with Vanta's core: managing controls and policies, collecting evidence, and preparing for audits. We verified each project's license, recent activity, stars, and self-hosting in its repository. Vanta is a hosted product with hundreds of integrations, so we flag open-core and source-available licenses and how broad each tool's coverage is. See our methodology for the full criteria.
A compliance platform organizes controls and evidence, but you still need an independent auditor to issue a SOC 2 or ISO 27001 report. Treat vendor claims about saved time or integration counts as marketing until you test them with your own systems.
Probo is MIT and Openlane is Apache-2.0. Comp AI is AGPL-3.0, but it is an open-core company, so some parts of the repository need a commercial license. VerifyWise uses the Business Source License 1.1, so it is source available rather than open source, with dual licensing for enterprises.
Probo and Openlane are the closest as compliance programs and automation platforms across frameworks such as SOC 2, ISO 27001, and GDPR. Comp AI adds AI-driven policy generation and automated evidence collection with device agents. VerifyWise focuses on AI governance for the EU AI Act and ISO 42001, not general compliance automation.
Probo is MIT, Openlane is Apache-2.0, Comp AI is AGPL-3.0 with commercial-only parts, and VerifyWise is BSL 1.1.
Probo, Openlane, and VerifyWise had commits within days of this update. Comp AI's last commit was in October 2026, and Openlane has a small community with about 324 stars.
Vanta is a proprietary hosted service priced by framework and company size, with compliance data stored on its platform and costs that rise quickly as you add frameworks. Open-source alternatives let you self-host compliance data, avoid per-framework fees, and extend the integrations, at the cost of less polished automation and fewer ready-made integrations.
Comp AI is an AI-driven compliance platform covering SOC 2, ISO 27001, HIPAA, GDPR, and FedRAMP, with automated evidence collection, generated policies, and device agents. The repository is AGPL-3.0, but Comp AI is an open-core company, so some parts of the repository require a commercial license.
Pricing: Free to self-host the open-source parts; commercial features and hosting are paid.
Probo is an MIT-licensed, self-hostable compliance management platform for SOC 2, GDPR, and ISO 27001, covering risk assessments, evidence collection, and auditor communication, with a hosted version available. It suits early-stage and growth-stage companies.
Pricing: Free to self-host; a hosted version is paid.
VerifyWise is an AI governance platform for the EU AI Act, ISO 42001, and NIST AI RMF, with a model inventory, bias monitoring, audit trails, and LLM evaluations, deployable on premises. It is licensed under the Business Source License 1.1, which is source available rather than open source, with dual licensing for enterprises.
Pricing: Free under the BSL terms; enterprise licensing and hosting are paid.
Openlane is an Apache-2.0 compliance automation platform that centralizes controls, evidence, and frameworks such as SOC 2, ISO 27001, NIST 800-53, and GDPR, and connects to existing tools. The code is open source, while Openlane's cloud services and branding are separate products.
Pricing: Free to self-host; the hosted Openlane cloud is paid.
