Comp AI vs Vanta

Last updated October 2026

Compliance automation has become a standard line item for startups and growth-stage companies chasing enterprise contracts. Two platforms sit at opposite ends of the market: Vanta, the incumbent with the largest customer base and integration library, and Comp AI, a newer entrant built on an open-source core that promises faster time to audit at a lower price point. Both help teams reach and maintain SOC 2, ISO 27001, HIPAA, and GDPR compliance, but they differ meaningfully in architecture, pricing philosophy, and where they expect you to invest your own engineering effort.

This comparison breaks down how each platform works, what it costs, and where it falls short so you can make a faster purchasing decision without sitting through two separate sales demos first.

Comp AI

Comp AI (trycomp.ai) launched in early 2025 under the legal entity Bubba AI, Inc. The platform raised $2.6M in a pre-seed round in mid-2025 and followed up with a $34M Series A in September 2026 led by Roo Capital and Grand Ventures. By October 2026, the company reports more than 1,000 customers and 15x year-over-year ARR growth, though those figures have not been independently audited.

The central pitch is straightforward: an AI-native compliance platform where roughly 99% of the codebase is open source under an AGPLv3 license, with a commercial enterprise edition layered on top for managed hosting, bundled audits, and premium support.

How it works

Comp AI connects to your cloud infrastructure and SaaS tools to pull evidence, draft policies, and run continuous compliance checks against your chosen framework. The platform uses AI to generate first-draft policies tailored to your organization, map evidence to controls, and flag gaps. The company claims that teams can reach a SOC 2 Type I audit-ready state in as few as 24 hours, though that timeline refers to the readiness checkpoint (policies drafted, evidence connected, gaps flagged) rather than the audit itself. A SOC 2 Type II report still requires an observation window of roughly three months that no software can compress.

The open-source core lives on GitHub under trycompai/comp and includes the substantive product: policy management, evidence collection, integrations, and auditor exports. Enterprise features sit in a separate /ee directory under a commercial license. Self-hosting requires your own PostgreSQL instance plus supporting services for email and background jobs.

Key features

Comp AI supports SOC 2, ISO 27001, HIPAA, and GDPR as compliance frameworks. The platform offers AI-powered policy drafting, automated evidence collection across 580+ integrations, continuous compliance monitoring, and a self-hosting option for teams that want full control over their data. The company bundles audit and penetration testing costs into the platform fee on managed plans and advertises a 100% money-back guarantee on audit outcomes, though the precise conditions of that guarantee should be confirmed with sales before purchase.

Pricing

Comp AI does not publish a single consistent price list, and earlier publicly listed tiers were reportedly retired in late 2026. The best available estimates from third-party sources suggest an entry tier around $199 per month for a single framework and smaller team, with enterprise managed plans ranging from $20,000 to $80,000 per year depending on company size and number of frameworks. A separate Comp AI content page references a $5,000 to $10,000 price point for SOC 2 compliance, which conflicts with the higher third-party estimates. The self-hosted open-source version is free at the software layer, but you absorb hosting, maintenance, backup, and upgrade costs internally. Request a written quote from sales that breaks out pricing by framework, and clarify what the bundled audit and penetration test cover.

Limitations

Comp AI is a young company with a small review base of roughly 70 G2 reviews compared to the thousands that incumbents carry. Pricing transparency is limited, and the gap between the company's own published figures and third-party estimates makes it harder to budget without a sales conversation. Self-hosting the open-source version is a realistic option only for teams with dedicated infrastructure or security engineering capacity, and it comes without the managed support, bundled audit, or bundled penetration test included in paid plans. The exact boundary between AGPLv3-licensed features and commercially licensed enterprise features is not well documented publicly. Some G2 reviewers have noted a learning curve and asked for better guided onboarding.

Vanta

Vanta is the largest compliance automation platform by customer count and has been the default recommendation in the space since its early traction with Y Combinator-backed startups. The platform covers a broad set of frameworks, offers deep integrations with cloud providers and SaaS tools, and has expanded into adjacent categories like vendor risk management, AI governance, and trust centers.

How it works

Vanta connects to your infrastructure and business tools through 400+ pre-built integrations, continuously monitoring your environment against the controls required by your chosen compliance frameworks. The platform automates evidence collection, flags misconfigurations, assigns remediation tasks to the right owners, and tracks progress toward audit readiness. When audit time arrives, Vanta streamlines the process by packaging evidence for your auditor and providing a shared workspace for the examination. The platform also includes a Connectors API and a GraphQL API for teams that need custom integrations or want to pipe Vanta data into other tools.

Key features

Vanta supports over 20 compliance frameworks, including SOC 2, ISO 27001, GDPR, HIPAA, HITRUST, CMMC, FedRAMP, NIS2, DORA, CPS 234, EU AI Act, Cyber Essentials, and the NIST AI Risk Management Framework. Teams can also build custom frameworks. Beyond core compliance, Vanta offers a Trust Center for sharing compliance documentation with prospects and customers, third-party risk management for vendor onboarding and ongoing security reviews, questionnaire automation for responding to security questionnaires at scale, access reviews with risk context, AI governance tooling, and a centralized "CISO view" that surfaces risk across the organization. The platform includes two-way integrations with task trackers so remediation work flows into existing project management tools.

Pricing

Vanta does not publish pricing. Third-party estimates for 2026 place the Core tier (1 to 25 employees, single framework, typically SOC 2) at roughly $10,000 to $15,000 per year. The Growth tier (25 to 100 employees, 2 to 4 frameworks) runs approximately $24,000 to $45,000 per year. The Scale tier (100 to 1,000+ employees, unlimited frameworks including custom ones) ranges from $50,000 to $120,000 or more per year. These are platform fees only. Auditor fees run separately at roughly $15,000 to $40,000+ per framework per year, paid directly to the audit firm. Adding ISO 27001 to an existing SOC 2 engagement typically adds 40% to 70% to the platform fee. Multi-entity deployments add another 40% to 80% per entity. Multi-year prepayment can reduce costs by 10% to 20%.

Limitations

Vanta's pricing is opaque and scales steeply with employee count, number of frameworks, and organizational complexity. A 50-person company pursuing SOC 2 Type II might spend $65,000 to $80,000 all-in during the first year when you factor in platform fees, auditor costs, and internal time. A 200-person company pursuing SOC 2, ISO 27001, and HIPAA could face $200,000 to $255,000 in total first-year costs. The platform is closed-source with no self-hosting option, so teams that need to keep compliance data within their own infrastructure will need to look elsewhere. Some users report that the breadth of Vanta's feature set introduces complexity during initial setup, and smaller teams may find themselves paying for capabilities like vendor risk management and trust centers that they do not yet need.

Comparison table

How to choose

If budget is your primary constraint, Comp AI is the more accessible starting point. The entry tier sits well below Vanta's floor, and the bundled audit and penetration testing costs remove two line items that can add $20,000 to $50,000 to a Vanta engagement. For seed-stage and Series A companies that need SOC 2 to close their first enterprise deals, Comp AI's lower total cost of ownership is a meaningful advantage.

If you need broad framework coverage, Vanta is the safer bet. Comp AI supports four frameworks today. Vanta supports more than 20, including specialized ones like FedRAMP, HITRUST, and CMMC that matter in regulated industries. If your compliance roadmap extends beyond SOC 2 and ISO 27001, Vanta's framework library reduces the risk that you will need to migrate platforms later.

If you want to self-host or control your data, Comp AI is the only option. Vanta is a closed-source SaaS platform with no self-hosting path. Comp AI's open-source core means you can run the compliance platform on your own infrastructure, audit the code yourself, and avoid sending sensitive evidence data to a third-party service. This matters most for companies in defense, government contracting, or other environments with strict data residency requirements.

If you need vendor risk management and trust centers, Vanta offers these as integrated features within the same platform. Comp AI does not list equivalent capabilities. For companies that field frequent security questionnaires from prospects or need to manage a large vendor portfolio, Vanta consolidates workflows that would otherwise require separate tools.

If you value ecosystem maturity and auditor familiarity, Vanta's years in market and thousands of customers mean that most compliance auditors are already familiar with the platform, its evidence packaging, and its report formats. This can reduce friction during the audit itself. Comp AI is growing quickly but has a smaller review base and less auditor familiarity, which may require more hand-holding during your first engagement.

If your engineering team wants to contribute or extend the platform, Comp AI's open-source model is a differentiator. You can inspect the codebase, submit patches, build custom integrations against the source, and avoid vendor lock-in at the platform level. Vanta's Connectors API and GraphQL API provide extensibility, but you are working within the boundaries of a closed platform.

Frequently asked questions

What is Comp AI?

Comp AI is an AI-native compliance automation platform built on an open-source core. It helps companies achieve and maintain compliance with frameworks like SOC 2, ISO 27001, HIPAA, and GDPR by automating policy drafting, evidence collection, and continuous monitoring. The platform launched in 2025 and offers both a free self-hosted version and managed plans with bundled audit and penetration testing.

What is Vanta?

Vanta is the largest compliance automation platform by customer count, founded in 2018. It automates the process of achieving and maintaining compliance with more than 20 security and privacy frameworks. The platform connects to your infrastructure and SaaS tools, continuously monitors your environment, and streamlines the audit process. Vanta also offers vendor risk management, trust centers, and AI governance features.

Is Comp AI free?

The self-hosted open-source version of Comp AI is free at the software layer. You can download the AGPLv3-licensed codebase from GitHub and run it on your own infrastructure. However, self-hosting means you take on the cost and responsibility of hosting, database management, backups, upgrades, and operational maintenance. Managed plans with bundled audit and support start at an estimated $199 per month.

How much does Vanta cost per year?

Vanta does not publish pricing. Based on third-party estimates for 2026, the Core tier starts at roughly $10,000 to $15,000 per year for small teams with a single framework. Growth tier pricing ranges from $24,000 to $45,000 per year, and Scale tier pricing ranges from $50,000 to $120,000 or more per year. Auditor fees are separate and typically add $15,000 to $40,000+ per framework per year.

Can Comp AI replace Vanta?

For companies that need SOC 2, ISO 27001, HIPAA, or GDPR compliance and want a lower-cost or self-hosted option, Comp AI can serve as a replacement. However, Comp AI does not currently match Vanta's breadth in framework coverage, vendor risk management, trust centers, or questionnaire automation. Teams with complex multi-framework requirements or large vendor portfolios may find gaps when switching from Vanta to Comp AI.

Does Vanta support custom frameworks?

Yes. Vanta's Scale tier includes the ability to build and monitor custom frameworks alongside the 20+ standard frameworks the platform supports. Custom framework setup may incur a one-time fee estimated at $10,000 to $30,000 depending on complexity.

Is Comp AI open source?

Roughly 99% of Comp AI's platform is open source under the AGPLv3 license. The core product, including policy management, evidence collection, integrations, and auditor exports, is available on GitHub. A commercially licensed enterprise edition adds features in a separate directory. The exact boundary between open-source and commercial features is not thoroughly documented.

How long does it take to get SOC 2 compliant with each platform?

Comp AI claims teams can reach a SOC 2 Type I audit-ready state in as little as 24 hours. Vanta does not make a specific time-to-compliance claim but is generally used over a period of weeks to months depending on the organization's starting posture. Both platforms require a separate observation window for SOC 2 Type II, typically around three months, which neither tool can compress.

Does Vanta offer a free tier or trial?

Vanta does not offer a publicly listed free tier or self-service trial. Prospective customers typically go through a sales demo and receive a custom quote based on company size, framework needs, and desired features.

Which platform has better integrations?

Comp AI reports 580+ integrations while Vanta lists 400+ pre-built integrations. Raw integration count is a rough indicator. What matters more is whether each platform connects to the specific tools in your stack. Vanta's integration library is older and more battle-tested, with premium connectors and a Connectors API for custom builds. Comp AI's integration count has grown rapidly but the depth and reliability of individual connectors may vary given the platform's younger age. Check both platforms against your specific infrastructure and SaaS tools before committing.

Can I switch from Vanta to Comp AI mid-audit?

Switching compliance platforms mid-audit is not recommended. Your auditor relies on consistent evidence collection and policy documentation throughout the observation period, and migrating platforms introduces gaps and inconsistencies that could delay or complicate the examination. The best time to switch is between audit cycles, ideally after completing a Type II report and before the next observation window begins.

Does Comp AI include audit costs in its pricing?

On managed plans, Comp AI bundles audit and penetration testing costs into the platform fee and offers a money-back guarantee on audit outcomes. This is a notable difference from Vanta and most other compliance platforms, where auditor fees are a separate cost that can run $15,000 to $40,000 or more per framework. Confirm the scope and conditions of the bundled audit with Comp AI's sales team before purchasing.
