What is Doppler?
Doppler is a secrets management platform that solves one of the most quietly dangerous problems in modern software: where to safely store and share the API keys, database passwords, tokens, and other credentials that applications need to run. Too often these secrets end up hardcoded in source code, copied into .env files, pasted into chat, or scattered across cloud consoles — any of which is a breach waiting to happen. Doppler centralises all of an organisation's secrets in one secure, encrypted place and delivers them to applications and team members safely, so credentials stop leaking through the cracks.
The platform organises secrets by project and environment (development, staging, production), so each part of your system gets exactly the credentials it should and nothing more. It syncs those secrets automatically to wherever they're needed — local development, CI/CD pipelines, cloud platforms, and container orchestrators — which means developers never have to manually copy a secret again, and rotating a compromised key is a single update that propagates everywhere instantly. Access controls determine who can see and change what, while detailed audit logs record every access and modification, giving security teams the visibility and accountability that compliance and good practice demand. Secret rotation and versioning further reduce the blast radius if something is ever exposed.
Doppler is built for development teams of every size that take security seriously, from startups establishing good habits early to larger engineering organisations managing thousands of secrets across many services. Its value is that it makes the secure path also the convenient path: developers get frictionless access to the credentials they need, while the organisation gets centralised control, easy rotation, and a clear audit trail. Given that leaked credentials are behind a large share of real-world breaches, a dedicated secrets manager like Doppler is one of the highest-leverage security investments a software team can make — protecting the keys to everything without slowing engineers down.

OncePad is free one-time secret and file sharing with no account. Your browser encrypts the secret. The link carries no key. You send the passphrase on a separate channel. It burns after one reveal, or after 24 hours if nobody opens it. Files up to 25 MB.
