Compliance platform that automates evidence collection, policy management and controls for teams pursuing SOC 2, ISO 27001, HIPAA or GDPR.
Getting audit ready is mostly clerical work, and that is the work Comp AI takes over. It automates evidence collection, policy management and control implementation for SOC 2, ISO 27001, HIPAA and GDPR, while the data and the infrastructure holding it stay yours.
The codebase is a Bun monorepo built on Next.js, with Prisma over PostgreSQL, Trigger.dev running background jobs, Tailwind CSS in the interface and Upstash Redis behind the key value store. It splits into the main application, a portal and an API, with shared packages for database access, email templates, key value access and UI components that are published to npm.
Running a local instance is a fairly involved setup.
- Runtimes: Node.js 20 or newer, Bun 1.1.36 or newer and PostgreSQL 15 or newer.
- Database: a Docker container, then Prisma generate, push or migrate, and an optional seed.
- Background jobs: a Trigger.dev project id wired into the trigger configuration file.
- Authentication: Google OAuth credentials with redirect URIs for both the app and the portal.
- Email and cache: a Resend API key for mail and an Upstash Redis database for key value storage.
Deployment guides for Docker and Vercel are both listed as coming soon, so self-hosters are currently ahead of the documentation. The company describes the project as open core, with the core under AGPLv3 and a small enterprise directory under a commercial license, and it invites discussion about where that line should sit. A hosted version is sold for anyone who would rather not run it.
Self-hostable GRC platform covering risk, controls, vendor risk, data privacy and audits, aimed at engineering and security teams.
Compliance work usually lives in spreadsheets and a vendor portal nobody wants to open. Probo is a self-hostable governance, risk and compliance platform built for engineering and security teams, covering the lifecycle from risk identification through control tracking, vendor risk, data privacy, access reviews and audit programs.
The backend is Go on PostgreSQL, the frontend is React with TypeScript, Relay and Tailwind CSS, and observability runs on OpenTelemetry with Grafana, Prometheus, Loki and Tempo. Every entity is reachable through more than one interface, which is what makes the automation possible.
Access to that data model comes in several shapes.
- Web console: the primary surface for day-to-day GRC work.
- prb CLI: over 44 command groups for scripting, automation and CI/CD integration.
- MCP API: more than 270 tools let any MCP-compatible agent read and write compliance data, draft policies and generate evidence packs.
- GraphQL API: the same model exposed for custom integrations, with an n8n community node for no-code workflows.
- Audit trail: policy-based RBAC, immutable logs and electronic sign-off with approval quorums.
Domain coverage includes a risk register with inherent and residual scoring, a control library with maturity levels and Statement of Applicability export, DPIAs and transfer impact assessments, vendor inventory with DPA and BAA tracking, and a public compliance portal on a custom domain. Running it locally needs Go, Node.js, Docker and mkcert. Probo is MIT licensed and Docker is the supported way to run it on your own infrastructure.
Compliance automation platform that holds policies, controls, evidence and vendors in one system of record for SOC 2 and ISO 27001 programs.
Compliance programs usually live in a spreadsheet beside the systems they describe. Openlane is a platform meant to be the system of record instead, holding the people, systems and vendors in scope, the policies and controls that govern them, and the evidence that proves it.
This repository is the core server and orchestration services behind the hosted product, written in Go. The stack is assembled from open source pieces so an operator does not need a dozen subscriptions to run it, among them PostgreSQL, Redis, S3 compatible storage, ent, gqlgen and OpenFGA.
The platform is organized into areas that build on each other.
- Compliance management: policies, controls, evidence and programs with approvals, comments and full history on every object.
- Frameworks: importable control sets for SOC 2, ISO 27001 and NIST 800-53, where one control can satisfy several frameworks.
- Registry: personnel, vendors and assets imported from a directory, a CRM, a CMDB or spreadsheets.
- Exposure: domain scanning and vulnerability feeds from GitHub, AWS Security Hub and GCP Security Command Center, with remediation tracking.
- Trust Center: a branded portal on your own domain publishing certifications, security documents and subprocessors.
- Access control: granular RBAC, organization wide SSO, 2FA enforcement and auditor views, none of it behind a paywall.
Running it yourself needs Go, Task and Docker and two commands, with container images published to the GitHub container registry, though Helm charts are not available yet. The code is Apache 2.0 while the cloud service and trademarks stay with the company.
