Infisical is an open-source platform designed for developers and infrastructure teams to securely manage application secrets, internal/external certificates, and privileged access without relying on proprietary tools. It eliminates manual secret handling and credential leaks by providing centralized, identity-based control over secrets across environments—from local development to Kubernetes and CI/CD pipelines. Built with TypeScript and Go, it supports self-hosting on-premises or in the cloud, integrates with PostgreSQL for storage, and offers a unified API, CLI, and SDKs for seamless adoption.
The platform unifies secret management, PKI certificate lifecycle control, and just-in-time access provisioning under one system, leveraging ACME, OIDC, and cloud-native auth providers. It’s deployed via Docker Compose, supports Terraform, Ansible, and AWS/GCP/Azure integrations, and is designed for compliance with SOC 2, HIPAA, and FIPS 140-3 standards.
What You Get
- Secrets Management Dashboard - Centralized UI to manage API keys, database credentials, and configs across projects and environments (dev, staging, prod) with role-based access controls.
- Secret Syncs - Automatically sync secrets to GitHub Actions, Vercel, AWS Secrets Manager, Terraform, Ansible, and other infrastructure tools without hardcoding values.
- Dynamic Secrets - Generate ephemeral, short-lived credentials on-demand for PostgreSQL, MySQL, and RabbitMQ, eliminating static credentials and reducing breach surface.
- Secret Rotation - Automate rotation of secrets for PostgreSQL, MySQL, AWS IAM, and other services at scheduled intervals to enforce least-privilege and reduce credential exposure.
- Secret Scanning & Leak Prevention - Scan git repos, files, and directories for 140+ secret types (e.g., AWS keys, JWT tokens) and block commits containing secrets via pre-commit hooks.
- Certificate Lifecycle Management - Issue, renew, and revoke internal and external certificates (Let’s Encrypt, DigiCert, AD CS) using profiles, policies, and enrollment methods like ACME or EST.
- Infisical Kubernetes Operator - Automatically inject secrets into Kubernetes pods and trigger pod restarts when secrets change, without modifying application code.
- Infisical Agent - Inject secrets into running applications at runtime without code changes, supporting any language or deployment environment.
- Signed SSH Certificates - Issue ephemeral, centrally managed SSH certificates for secure, time-bound access to servers and infrastructure, replacing static SSH keys.
- Audit Logs - Track every secret access, modification, or deletion with full context, including user, timestamp, and action type for compliance and forensic analysis.
- Access Controls with RBAC & Temporary Access - Define granular permissions for users and machine identities, enforce just-in-time access, and require approvals before secret changes propagate.
- Infisical KMS - Centrally manage symmetric cryptographic keys and use them to encrypt/decrypt data via API or SDKs, supporting AES-GCM-256 encryption.
- Infisical CLI - Interact with Infisical from terminals and CI/CD pipelines to fetch, inject, and scan secrets without UI dependency.
- Infisical API & SDKs - Programmatically manage secrets and certificates via REST API and official SDKs for Node.js, Python, Go, Ruby, Java, and .NET.
- Self-Hosting Support - Deploy Infisical on your own infrastructure using Docker Compose, with full control over data residency and network isolation.
- Certificate Syncs - Automatically sync issued certificates to AWS Certificate Manager and Azure Key Vault for centralized certificate storage and usage.
- Alerting for Expiring Certificates - Configure notifications for CA and end-entity certificates nearing expiration to prevent outages.
- Multi-Cloud Auth Providers - Authenticate machine identities via Kubernetes, GCP, Azure, AWS, OIDC, and Universal Auth for seamless integration into existing identity systems.
Common Use Cases
- Running Kubernetes workloads securely - A DevOps engineer uses Infisical’s Kubernetes Operator to inject encrypted secrets into pods and auto-reload deployments, eliminating hardcoded credentials and reducing attack surface.
- Preventing secret leaks in CI/CD pipelines - A SRE team integrates Infisical’s secret scanner with GitHub Actions to block commits containing AWS keys or database passwords before they reach production.
- Managing internal PKI at scale - An enterprise IT team uses Infisical’s Private CA to issue and revoke internal TLS certificates across 500+ microservices, replacing manual OpenSSL workflows.
- Enabling just-in-time access for on-call engineers - A security team grants temporary SSH access to production servers via signed certificates, automatically revoking access after 2 hours with full audit trails.
- Securing AI agent tool access - An AI platform team uses Agent Sentinel to control which external APIs and tools AI agents can access, enforcing authentication and policy checks at runtime.
- Compliant secret management for HIPAA/SOC 2 - A healthcare SaaS company self-hosts Infisical to maintain data sovereignty and meet compliance requirements with audit logs, encryption, and access controls.
Under The Hood
Architecture
- Backend follows a clean layered architecture with well-defined controllers, services, and repositories, using Knex.js for database abstraction and custom dependency injection containers
- Monorepo structure cleanly separates frontend and backend with shared TypeScript interfaces, ensuring type safety across boundaries
- Database operations are decoupled via migration-first workflows and adapter patterns, enabling multi-database support without polluting business logic
- Observability is deeply integrated with OpenTelemetry and Prometheus through middleware and structured exporters, preserving separation of concerns
Tech Stack
- Node.js backend with TypeScript, Fastify, and Knex for robust API development and database interactions, with PostgreSQL as the primary datastore
- Frontend built with Next.js and React, leveraging server-side rendering and static generation for performance and SEO optimization
- Infrastructure is orchestrated via Docker Compose with environment-aware configurations for testing, replication, and monitoring services
- Enterprise-grade cryptographic operations are handled by SoftHSM and Pebble ACME, with automated certificate lifecycle management
- CI/CD pipelines are automated through Makefiles, Render.com, and Helm charts, ensuring seamless deployment readiness
Code Quality
- Extensive test coverage across unit, integration, and end-to-end layers using Vitest and supertest, ensuring reliability of critical paths
- Clear separation of concerns through service-layer abstractions, data access layer patterns, and factory-based dependency injection
- Consistent error handling with custom error classes for authentication, permissions, and data access, improving debuggability and user experience
- Strong TypeScript typing enforced via interfaces and type factories, ensuring precise modeling of database queries and API responses
- Modular organization with dedicated folders for e2e, lib, and enterprise modules, complemented by rigorous linting and mocking practices
What Makes It Unique
- Implements RFC-compliant OAuth 2.1 metadata endpoints to enable dynamic, machine-to-machine identity discovery for AI agents and third-party systems
- Deeply integrates AWS Private CA into the secrets workflow, automating certificate issuance, rotation, and revocation as first-class operations
- Unifies static secrets and dynamic PKI-based certificates in a single platform, bridging infrastructure and application security domains
- Uses a plugin-style architecture for KMS and CA providers, allowing extensibility without vendor lock-in or code duplication
- Combines machine identity discovery with secrets management through declarative API contracts powered by Zod and Fastify, reducing attack surface and improving interoperability
