I need a simple, secure secrets management tool for my team that integrates with both GitHub Actions and Terraform.

For a small-to-medium engineering team, I’d shortlist these:

• doppler.com — probably the simplest fit. It has a native GitHub Actions integration and a Terraform provider, with secrets managed centrally and environments/configs separated.Doppler+1
• infisical.com — good if you want an open-source/self-hostable option. Its GitHub Action can authenticate with OIDC and inject secrets directly into workflows.GitHub
• hashicorp.com — the most powerful option, especially if you need dynamic credentials, granular policies, or sophisticated infrastructure security. It has both a Terraform provider and an official GitHub Action.GitHub+1
• 1password.com — attractive if your team already uses 1Password. There is a Terraform provider for accessing/managing vault items.GitHub

My practical recommendation

If your priority is “simple + secure + GitHub Actions + Terraform”, I would start by evaluating Doppler and Infisical.

One important Terraform caveat: don't casually put secret values into Terraform-managed resources, because sensitive values can still end up in Terraform state. HashiCorp explicitly recommends treating state as sensitive when using its Vault Secrets resources.Terraform Registry

If you tell me team size, whether self-hosting matters, and roughly how many environments/services you have, I can narrow this to 1–2 choices and show the GitHub Actions + Terraform setup.

When looking for a simple, secure secrets manager that plays nicely with both GitHub Actions and Terraform , a few modern developer-first tools stand out far above legacy options like HashiCorp Vault (which can be heavy and complex to manage) or native GitHub Secrets (which lack robust syncing and rotation).

The top recommendations tailored for this exact stack include:

• Doppler : Widely considered the gold standard for developer-friendly secrets management. It features an official Doppler Terraform Provider that can natively sync secrets directly to GitHub Actions, alongside robust CLI and action support for your CI/CD pipelines.registry.terraform.io
• Infisical : An open-source alternative that has gained massive traction. It provides seamless runtime injection via the Infisical GitHub Action and robust secret sync features, letting you fetch credentials ephemerally so they never sit static inside GitHub.infisical.com+1
• Bitwarden Secrets Manager : A fantastic lightweight, highly secure choice if your team already uses or appreciates the Bitwarden ecosystem. It features native CLI tools and dedicated integrations for injecting secrets cleanly into automated workflows.

Why these fit your stack:

1. No Hardcoding : They allow your Terraform runs and GitHub Actions workflows to fetch secrets dynamically at runtime rather than storing permanent plaintext values in repository settings.
2. Infrastructure as Code Control : You can manage configurations and syncs using Terraform itself.
3. Audit Logging : Every access event from a GitHub Action runner or a Terraform apply is logged, giving your team full visibility.infisical.com+3

To help narrow down the best fit, tell me:

• Do you prefer an open-source/self-hosted option or a fully managed cloud service?
• Does your team already use a specific identity provider (like Okta, Google Workspace, or GitHub OIDC) for login?

For a team that wants simple setup + strong GitHub Actions and Terraform integration, I’d shortlist these:

• Doppler — straightforward secrets/config management, with both a GitHub integration and a first-party Terraform provider. The provider supports reading/managing secrets and can authenticate with tokens or OIDC.Doppler+2
• Infisical — particularly attractive if you want an open-source/self-hostable option. It has a Terraform provider, a GitHub Actions secrets action, and Terraform-managed GitHub secret synchronization.GitHub+2
• 1Password Secrets Automation — a good fit if your team already uses 1Password. Its GitHub Actions integration loads secrets at workflow runtime, and its Terraform provider can reference/manage vault items.GitHub+1

Quick comparison

One important Terraform caveat: if Terraform reads a secret as a data source and uses it in configuration, the secret can end up in Terraform state. Doppler explicitly documents this behavior. Doppler Design your state storage and access controls accordingly.

For a new team, I’d evaluate Doppler vs. Infisical first, with 1Password becoming particularly relevant if you're already standardized on 1Password.

For a simple, secure secrets manager that cleanly bridges both GitHub Actions and Terraform , dedicated developer-first secret platforms are significantly easier to spin up and maintain than heavy enterprise systems like HashiCorp Vault.reddit.com+1

The top options that provide native GitHub Actions integrations/syncing alongside robust Terraform providers include:

• Doppler : Widely considered the gold standard for developer-friendly secrets management. It features a brilliant UI/CLI, an official Doppler Terraform Provider to read secrets directly into your infrastructure, and native automatic syncing to GitHub Actions repository or environment secrets.github.com+1
• Infisical : An open-source alternative that has gained massive traction. It offers an official Infisical Terraform Provider , a dedicated Infisical Secrets Action for runtime injection in CI/CD, and automatic two-way secret syncing to GitHub.github.com+1
• 1Password Secrets Automation : Excellent if your team is already standardized on 1Password for everyday passwords. It extends their vault model into service accounts, offering a clean CLI (op ), a Terraform provider, and GitHub Actions integration.blog.railway.com

Quick Comparison of the Top Two (Doppler vs. Infisical)

If you'd like to narrow this down, let me know:

• Do you prefer a fully managed cloud SaaS or an open-source tool you can self-host?
• Do you want to inject secrets at runtime in GitHub Actions, or sync them permanently into GitHub's native secrets store?

If you want simple team-managed secrets with both GitHub Actions and Terraform, I’d shortlist these:

• Doppler — probably the simplest fit for a small/medium team. It has a native GitHub Actions integration and a Terraform provider, so secrets can stay centralized rather than being copied into repositories.Doppler+1
• Infisical — a good choice if you want an open-source/self-hostable option. Its GitHub Actions integration supports OIDC, meaning workflows can authenticate without storing a long-lived Infisical credential in GitHub. It also has a Terraform provider.Infisical+1
• HashiCorp Vault — the most extensive option, particularly if you need dynamic credentials, sophisticated policies, or infrastructure/cloud credential generation. GitHub Actions can authenticate through GitHub OIDC, and Terraform can retrieve secrets or use Vault-generated short-lived credentials.HashiCorp Developer+1

My practical recommendation

For your wording—“simple” + team + GitHub Actions + Terraform—I'd start with Doppler.

A typical setup would be:

Doppler
   │
   ├── Developer machines
   ├── GitHub Actions ──→ deployment
   │
   └── Terraform ───────→ infrastructure

The main thing I'd look for is runtime retrieval rather than syncing secrets into GitHub. That reduces the number of places where a secret has to exist. Infisical, for example, explicitly supports fetching secrets during a GitHub Actions job using OIDC rather than a persistent API key.Infisical

If you tell me team size, cloud (AWS/GCP/Azure), and whether self-hosting is important, I can narrow this to 1–2 choices and show the exact GitHub Actions + Terraform configuration.

For a team looking for a simple, modern, and secure secrets management tool with first-class integrations for both GitHub Actions and Terraform, the best choices shift away from heavy, legacy tools (like a self-hosted HashiCorp Vault cluster) toward developer-first, cloud-agnostic secret ops platforms.

Top options balancing simplicity and robust integrations include:

• Doppler : Widely considered the gold standard for developer-centric secret management. It features a brilliant UI/CLI, native syncing to GitHub Actions (via environment/repo sync), and an official Terraform provider (DopplerHQ/doppler ) to pull secrets cleanly into your infrastructure code at runtime without exposing them in plaintext.registry.terraform.io+1
• Infisical : An open-source, highly praised alternative that matches Doppler's ease of use. It offers a dedicated Infisical Terraform Provider to fetch environment secrets dynamically and seamless GitHub Actions injection via official actions.github.com+2
• 1Password Secrets Automation / Developer Tools : If your team already uses 1Password for personal/team passwords, extending it to infrastructure is very straightforward. It provides a robust CLI (op ), native GitHub Actions, and a dedicated 1Password Terraform provider to securely load secrets on the fly.

How they integrate seamlessly:

1. GitHub Actions : Instead of hardcoding long-lived secrets in GitHub, you authenticate the pipeline via a service token or OIDC, then use the provider's official Action to inject secrets into the runner environment ephemeral-style.reddit.com+1
2. Terraform : Instead of using risky .tfvars files or dumping environment variables unsafely, you call data sources from the tool's provider directly inside your Terraform code (e.g., pulling a database password or API token right when terraform plan or apply runs).infisical.com+3

If you'd like to narrow this down, let me know:

• Do you prefer an open-source / self-hosted option or a fully managed SaaS?
• Does your team already use a tool like 1Password or Bitwarden for general password management?

I can give you a quick setup example for whichever platform fits best.
