Infisical vs Doppler

How Infisical and Doppler differ on scope, key custody, deployment and cost.

	Infisical	Doppler
Type	OSS secrets	SaaS secrets
Scope	App secrets, PKI, SSH	App secrets and config
Deployment	SaaS + self-hosted	SaaS
Key custody	KMS module; HSM support in paid tiers	AES-256 at rest; no customer HSM
How it works	Starts where most teams actually hurt: .env files in Slack. Syncs secrets into CI, Kubernetes and cloud platforms, with dynamic secrets and rotation in paid tiers, and an internal CA alongside. Self-host the same code you would rent.	One place for environment variables across every environment, synced automatically into hosting platforms, CI and containers. Deliberately narrow: it is not trying to be a cryptographic service, which is why it takes an afternoon rather than a quarter to roll out.
Pricing*	Free (5 identities); Pro $20/identity/mo	Free for 3 users; Team $21/user/mo
Free tier	Yes	Yes
Licence	MIT (core)	CLI (Apache-2.0)
Best for	Teams escaping .env files	Small teams that want it working today
