RunEnv vs HashiCorp Vault
Teams often compare RunEnv with HashiCorp Vault when they want secrets management without operating Vault as a specialist platform. Vault is a secrets engine that organizations typically run as infrastructure, with KV storage, dynamic credentials, policies, and a transit engine. Confirm current Vault editions and features in HashiCorp documentation. This page states what RunEnv does today.
At a glance
RunEnv facts versus a HashiCorp Vault category snapshot.
The RunEnv column is the supported product. Confirm current HashiCorp Vault capabilities in HashiCorp Vault documentation before a purchasing decision.
| Dimension | RunEnv | HashiCorp Vault |
|---|---|---|
| Category | Team environment-variable workspace, runtime injection, and credentialless agent actions. | Infrastructure secrets engine commonly used for KV, dynamic credentials, policies, and transit encryption. |
| Who operates it | Developers, QA, and platform teams can use dashboard, CLI, Desktop, and Agent Guard against one project/environment model. | Vault is commonly owned by platform or security engineering. Confirm current operational model in HashiCorp documentation. |
| Runtime / .env files | `runenv run` injects authorized values into the child process without writing `.env` on that path. | Applications typically authenticate to Vault and fetch secrets through Vault agents, templates, or SDKs. Confirm current Vault injection patterns in HashiCorp documentation. |
| Dynamic secrets and transit | RunEnv documents dynamic secrets and a transit encryption API. Scope and provider coverage are those of the current RunEnv docs, not a Vault compatibility claim. | Vault is widely used for dynamic credentials and transit. Confirm current secrets engines in HashiCorp documentation. |
| AI agents | Agent Guard gives coding agents approved actions, not general secret-read access or connector credentials. | A Vault token in an agent prompt or MCP config is a standing credential. Confirm HashiCorp’s current agent guidance independently. |
| Moving from Vault | RunEnv currently accepts pasted JSON import. It does not speak Vault’s API as a migration product and does not import policies, mounts, or leases. | Vault remains an appropriate control plane when you need Vault’s engine model. Switching is an architecture decision, not a file copy. |
Choose HashiCorp Vault if
- You already operate Vault as the organization secrets engine and need its current engine set.
- You need a Vault-specific integration, replication, or policy model that RunEnv does not document.
- You need a supported Vault-to-RunEnv migrator. That workflow does not exist today.
Choose RunEnv if
- Developers, QA, and coding agents need a project/environment workspace rather than a Vault cluster.
- You want `runenv run` and Agent Guard without giving agents a Vault token.
- You want Change Requests, environment diff, and Desktop compare in the same product.
RunEnv is not a Vault replica
RunEnv has overlapping ideas — encrypted storage, dynamic credentials, transit, namespaces — but it is not a drop-in replacement for a Vault cluster. Do not assume engine-for-engine parity.
- Use Vault when the organization standard is Vault’s policy and engine model.
- Use RunEnv when the pain is shared `.env` files, runtime injection, and agent actions without standing credentials.
- Keep both only when the boundaries are explicit.
What RunEnv can say about itself
The server decrypts values for authorized callers. That is envelope encryption with authorization, not a zero-knowledge vault. File delivery modes can write to disk. Those limits stay visible on this page on purpose.
